Domestic mold industry to accelerate the integration process in various fields

In recent years, the domestic mold exports increasing level of international competitiveness has improved . But mostly concentrated on middle and low areas , low mold technical level, low value-added, high-precision molds also part dependent on imports , so the domestic mold industry in various fields to strengthen integration.
China mold industry after decades of accumulated technology and in recent years to increase international exchanges , pay close attention to technological innovation in production technology have achieved significant breakthroughs in business with more competitive , the  PE Electrofusion Pipe Fitting industry expects 2015 sales value of China's mold will reach 350 billion yuan .
Throughout the development process, related industries and businesses need long-term perspective , the potential lower mind, pay close attention to new technologies, new technology research side , and gradually form a division of labor , there is collaboration in all areas of research and development pattern, introduced with proprietary mold products. Now China's mold industry through the introduction of foreign capital , absorb the advanced experience of foreign mold manufacturing , advanced technology and high-level talents , our mold design and manufacturing level has been greatly improved. More importantly , "five " the implementation of development policies and emerging strategic industries, regional development planning and policy to revitalize the equipment manufacturing industry will die industries are providing new growth point. With manufacturing in developed countries have to transfer to China , China's mold industry is facing a new round of development opportunities. Forecasts , and the internal and external drives Qi moving environment , to 2015, China's mold will reach 350 billion yuan sales value . China's mold industry is currently experiencing competitive pressures are mainly price advantage and technological superiority of developed countries to developing countries , need to know not only the development and progress of industrial molds China , Southeast Asia and Eastern European countries in recent years, the development of industrial molds are very fast , its advantages in terms of mold price obviously, this weakens the cost and price advantage of China 's mold industry has always been a certain extent . In addition, Western Europe, Japan and South Korea on the strength of the high-end market, but also to mold China mold industry is facing enormous challenges , " With the increasing domestic demand in China can be expected to die by 2013 China will have a larger growth industry , especially the automotive industry , has led to the rapid  chinese mould development of China's mold industry , promote the rapid transformation and upgrading of mold enterprise . " Luo Baihui mold experts believe , strengthen independent innovation in the industry change the growth mode , optimizing industrial structure , have a greater need high levels of mold machinery and equipment, providing a broad development space for the development of mold industry. Although China is the largest producer of the mold , the mold is not producing power. Our metal mold industry is constantly exploring the development of innovative technology, precision molds , has been able to independently produce plastic molds for mobile phone cameras , multi-cavity molds, and other small modulus gear ; rear axle gear box car die casting , escalators overall pedal casting molds and other large sophisticated die casting mold and die casting automotive engine casing also achieved good results. However , the overall market in China's mold sophisticated high-end mold is still relatively dependent on imports , mainly middle and low product is still expanding market development will take time. However , on this basis , a serious shortage of research funding , research is weak , there is no conducive to innovation in public technical support system. To narrow the gap , we must increase research and development, based on innovation, improve the quality sectors of the economy . At present, China's mold industry is entering a critical period of development. The development of the manufacturing sector in particular, the automotive industry , to promote the domestic mold market continues to expand, our foreign customers to purchase the number of mold growing international trend of China's mold manufacturing gradually shift is obvious . China Die Mold Industry Association forecast that domestic market continues to improve, China's mold industry will maintain a growth rate of around 20 %. 2013 Government continues to hand steady growth, thus stimulating investment growth accelerated again. It is predicted that China Investment Association , the 2013 investment will be more than 45 trillion yuan . In recent years , the domestic mold industry investment and construction in full swing, as an economic phenomenon , has attracted more and more attention and attention. Mold industry cluster to optimize the industrial structure, promote industrial upgrading and transformation of economic growth, improve the level of economic development , enhance regional economic competitiveness and prosperity party people have a very important strategic significance.
1:100 driving effect according to the argument , to the end of 2013 , Chinese investment can be more than 45 trillion yuan , then mold industry new investment will account for about 1% , then, the mold industry, the scale of investment will reach 450 billion yuan , which is one can foresee good prospects . As China's economy continues to develop, China 's manufacturing industry has also begun to develop Chinese characteristics mold , which industry experts put forward eight requirements: 1 , creativity , innovation and development . Necessary part of the development of innovative technology industry for China's mold industry is concerned , this is the main thing.
2, the supply and demand cooperation for the upgrade. At this stage, China's mold industry is a relatively large supply  plastic coupler fittings mould and demand instability problem of excess production of low-end products , high-end products rarely now more critical in the transformation and upgrading . 3 , a boutique brand quality . Many products on the domestic market gradually die mature stage, and increase brand awareness can better provide a broader market for the mold . 4 , to promote low carbon green growth . Pollution prevention, energy conservation is a prerequisite for the development of the industry. 5 , self- regulate insurance harmony. The quality of the industry is to enhance the basic product . 6 , organization building specialization. Improve the professional talent pool mold industry is the focus of future development . 7 , the industry coalition advocating standards. Industry alliances and technical cooperation development is an excellent mold transition implementation. 8, the exhibition business expand horizons. The exhibition was held to carry out other activities , whether domestic or international , has a great space for the exchange industry .

Domestic mold industry system by significantly expanding the potential market is

The most important aspect is to support the development of national industry , and gradually practice coupled with enterprise reform , the front line of China's industry has a great help.
After years of industrial development, China mold manufacturing has made ​​certain achievements , such as the formation  2 inch pvc coupling mould of the car has "four " industrial system. Today, industrial production increasing demands for mold manufacturing also put forward higher requirements . China mold manufacturing is based on existing technology to accelerate research and development to meet market demand . China 's cheap labor cost advantage and overall good momentum of sustained and rapid economic development, China's mold industry to bring good development prospects , projected to 2018 , China became one of the world's largest mold manufacturing base.
Progress over the years in the mold industry , prompting the emergence of a large number of leading companies , such as automotive panel die there , " four people" , the mold industry has 95 companies were awarded the " China mold of key enterprises" ; in the industrial  plastic injection mould layout , China's mold industry is expanding to the mainland and north from the more developed Pearl River Delta, Yangtze River Delta region , there are some new mold production more concentrated areas. More importantly , China's mold industry is not only large , but also more abundant grade , large-scale , sophisticated, complex, long-life high-level representatives of the mold to mold the proportion reached 35% or more .
But the overall level of the mold industry is still lagging behind the international advanced level, mold output still can not meet the market demand mold , mold on the domestic market  electrofusion coupling mould to meet the rate of less than 80% , especially high levels of mold technology in high-end mold , to meet the rate of less than 60% .
Therefore , China's mold industry should vigorously develop advanced science and technology , widening the scope of application of technology in a timely manner will die of advanced technology into productivity to meet the growing demand of China's mold market and promote the rapid development of China's economy and growth .

The main categories of plastic molds

According to different molding methods can be divided into the corresponding requirements of the different process types of plastics processing molds , mainly injection mold , extrusion mold, plastic mold, high mold foamed polystyrene and the like. 1, plastic injection ( plastic ) molds it is mainly the production of thermoplastic products in the most common type of mold, plastic injection mold corresponding processing equipment is plastic injection molding , plastic injection molding machine in the  PE Electrofusion Pipe Fitting first heat heating barrel bottom melted and then push in the plunger or a screw injection molding machine , injection machine nozzle and the mold after the casting system into the mold cavity , and cooled and solidified plastic molded article obtained release .

Manufacturing materials commonly used plastic mold steel modules, the material used mainly for carbon structural steel, carbon tool steel , alloy tool steel, high speed steel. Injection molding processing methods usually only suitable for hot plastic goods products production, injection molding process to produce a wide range of plastic products , from daily necessities of life to all kinds of complex mechanical , electrical appliances , vehicles and other parts are made of injection molding , it is the production of plastic products, the most widely used as a processing method . 2 , plastic compression molds
Including pressure injection molding and compression molding two structures mold type. They are mainly used for forming a class of thermosetting plastic mold , it corresponds to the device is a pressure molding machine. The plastic properties of the compression molding method , the mold is heated to a molding temperature ( generally 103 ° -108 °), and then compression-molding the powder into a good measure of the mold cavity and the loading chamber , closing the mold , heat and high pressure in the plastic viscous flow was softened , after a certain curing time setting, into a desired shape of the article . Pressure injection molding and compression molding except that End Cap mould  no separate loading chamber , before forming the first mold is closed , the room warms up in the feed of plastic viscous flow state was in the mold cavity pressure adjusting squeeze hardened molding. Compression molding of thermoplastic mold also used some special molten thermoplastic such as difficulty ( such as poly vinyl fluoride ) rough ( cold forming ) , high optical performance resin lenses , light foam nitrocellulose car steering wheel . Compression molds mainly by the cavity , chamber , guide mechanism , introduced parts, heating systems and other components. Pressure injection molds are widely used in packaging aspects of electrical components . Pressure plastic mold manufacturing and injection molds used basically the same material . 3 , plastic extrusion dies
Used to produce a continuous shape forming a kind of mold plastic products , also known as extrusion head, is widely used in processing pipe, bar, single wire, sheet, film , wire and cable coating , profiles , etc. . Corresponding production equipment plastic extruder, the principle is solid plastic is melted at a screw rotation of heating and pressurizing conditions of the extruder , plasticized by the particular shape of the die made ​​of the same cross-sectional shape of the die and continuous plastic products. Manufacturing materials are carbon steel, alloy tool , and some in the extrusion die components will need to wear resistant materials such as diamond studded . Extrusion process is generally applicable only thermoplastic engineering plastics products manufacturing , with injection molds and compression molds have obvious differences in the structure. 4 , plastic blow mold for molding plastic containers are hollow products ( such as beverage bottles , cosmetic containers and other packaging ) in a mold , in the form of blow molding process according 2 inch pvc coupling mould  to the principles of the main extrusion blow molding , injection blow molding, injection stretch blow molding ( commonly known as " injection stretch blow" ) , multi-layer blow molding, sheet blow molding. Blow molding hollow articles is usually referred to as a device corresponding to the plastic blow molding machine , blow molding is only applicable to the production of a thermoplastic product varieties . Blow mold structure is relatively simple, the materials used are manufactured mostly of carbon and more . 5 , plastic is plastic mold plastic plates, sheets of material forming a mold plastic products, some of the more simple , the principle is the use of a vacuum pump or compressed air method bloom forming method of the fixed die or punch in on plastic plates, sheets, in the case of heating and softening deformation posted on the desired mold cavity molding products , mainly for some daily necessities , food , toys and packaging products production. Plastic mold due to low pressure molding , mold material so multi-use aluminum or non-metallic materials , the structure is relatively simple. 6 , high foam polystyrene mold is the application of polystyrene ( consisting of polystyrene beads and foaming material ) forming a mold of various materials to the desired shape foam packaging materials. The principle is in the mold can be made of polystyrene can be molded into steam , including simple hand-operated hydraulic straight- mold and mold are two types of foam , is mainly used to produce industrial goods packaging products. Such mold material with aluminum, stainless steel, bronze and the like.

Mold can be reused - high speed slope mold

With our high-speed rail , high-speed , continuous water conservancy construction , such as high-speed slope mold plastic mold growing heterosexual , it 's kind of sizes have sprung up .
High-speed slope mold as a mold slope , its wide range of applications . For high-speed mold slope very stringent 2 inch pvc coupling mould  requirements specification , and I produced the high-speed slope mold with high brightness, strong toughness , not easily deformed and broken rate and other characteristics. We all know that high-speed mold slope is based on the size and specifications to determine the selection of plastic molds for large quantity production to improve the daily production volume , while plastic mold can be recycled , so you can save most of the resources. High-speed slope mold has good market prospects , oh.
We all know that when using the machinery must pay attention , otherwise there will be a lot of problems , Curb mold as well. So what precautions Curb mold it ?
Curb die in the course will always be PE Electrofusion Pipe Fitting  some problems , Curb mold plastic molds for the selection of raw materials , plastic mold easily oxidized in air oxidation easily become brittle plastic mold , plastic mold causes breakage rate improve , resulting in unnecessary trouble, while Curb mold can be recycled a hundred times , there may be deformed, so use will prevent mold next to prevent deformation. Plastic mold can be recycled after use , lower costs, reduce waste of resources.

Mold industry focus the strategic restructuring

Standing in a global perspective , China's demand is a big country mold , mold is also a big country . However, to meet the economic development needs of the industry , you must import large quantities of high- mold products. Therefore , be sure to pay attention to the domestic mold industry strategic adjustment of product structure , improve market access threshold to avoid the low end of the homogenization phenomenon.
It is understood that sales of  Pipe Plug
  domestic mold industry as a whole has nearly 250 billion yuan . In recent years, the development of a new mold industry cluster development of the industry characteristics , the formation of Kunshan , precision mold production base industry clusters ;
However , due to the late start of China's mold industry technology , with the developed countries there is not a small gap. In recent years , China's mold industry through the introduction of  pipe reducing coupling mould foreign capital , absorbing the advanced experience of mold manufacturing , advanced technology and high-level talents , our mold design and manufacturing level has been greatly improved , the current development momentum of China's mold industry for the better , with the , the machine tool industry should pay attention to the new demands of its development , the two sides in order to achieve a win-win situation.
At this stage, given the importance of domestic machine tool industry is not in the mold industry equipment and domestic equipment market share in this market is low , the mold tool industry experts suggest should pay close attention to the development of mold industry , attention PE Electrofusion Pipe Fitting  to mold industry equipment market , should be long-term development starting from a strategic perspective to understand , and the full study and correct positioning of the market. Thus, the domestic mold industry in the future development , be sure to pay attention to the strategic adjustment of its product structure , so that the structure of the complex , high-precision high-grade die faster development .

Mold industry demand growth trend of differentiation

This year, affected by many factors, such as complex domestic and international environment, face greater downward pressure on industrial growth. In the main tone of steady growth, expanding domestic demand, various policies have been launched to promote the rapid and steady growth in investment, and promote the overall recovery in the mold industry, China's industrial economy is generally stable, steady progress in structural PE Electrofusion Pipe Fitting  adjustment, industrial growth is expected in 2013 more than 15 die % international environment is still full of complexity and uncertainty, shrinking external demand situation is difficult to significantly improved, and because of slower growth in factor inputs, reduced efficiency of industrial investment mold, mold industrial economic downward pressure is still large. Three die stimulating industrial growth demand trends differentiation, will present investment stabilized, soft consumer trends, exports slowing trend. Investment, the direction is clear and the lingering effects. Domestic construction boom emerged Mold City, Mould Industry Mould City real estate investment and investment growth showed an upward trend. Commercial real injection mould  estate bubble of the past few years the development of aspects of resource allocation, economic structure and income distribution have had a serious negative effect, so the current round of real estate regulation will exceed the previous cycle. Meanwhile, the real estate investment and export demand and other related real estate and mold manufacturing to industrial markets to high-end development, mold manufacturing investment growth could rise further this year compared. Investment expansion in the mold industry is likely to shift the focus of urban transportation and other infrastructure as well as LED, medical and other industries, thus promoting investment in infrastructure and social services increased investment. Moreover, taking into account the investment in fixed assets this year, the total investment in new projects and is currently picking up the cumulative growth rate maintained at a relatively high level since May this year, which bodes well for next year's fixed asset investment growth is likely not to some extent there will be a substantial decline in the case of virtual tired out, the investment continues to be an important force for steady growth.
Although large-scale infrastructure investments no longer exist, but to show steady growth taking into account the national macro-policy effectiveness, investment in infrastructure, construction and other city will die steadily, more likely in 2013 to stabilize the growth of mold industrial investment, estimated annual growth rate of industrial investment mold maintained at more than 30% of fixed asset investment growth will remain at around 20%. Consumption, endogenous firmer but growth is slowing down. Canceled by the vehicle purchase tax incentives, real estate purchase, the impact of restricting the number of car Yaohao factors such as policy control, since this year the growth rate of real consumption of Chinese residents remained at low volatility. Although prices continued slow growth, personal income tax policy to gradually adjust and continue to expand social protection surface and other factors will tend to lead to enhanced endogenous consumption, but to promote income distribution reform will take time, relying on the consumer to stimulate economic growth in the short-term model difficult to establish. Taken together, the overall growth in consumer demand will remain modest growth trend slightly soft trend, consumption growth is expected to remain at around 14.5%. Export growth will remain low. From the outside, the slow U.S. economic recovery will continue to support China's exports to the United States to  tapping tee electrofusion mould maintain moderate growth, and sustained decline in the European economy and the slowdown in emerging economies will affect the overall performance of China's exports; from the internal point of view, China's population structure changes in factor prices and environmental reforms, such as strengthening the supply-side changes will further push production costs for the mold industry competitiveness and exports have a significant negative effect. In addition to the above factors, taking into account the appreciation of the renminbi and rising protectionism in trade and other factors, external demand in the longer term will remain weak state, the future is not as a stabilizing force in supporting industrial growth. Think of mold industrial export growth will moderate growth, showed significant slowing trend, but the possibility of a further sharp decline in the smaller mold industry estimated annual export value growth remained at around 10%. On the whole, taking into account the stimulating effect, the base effect of macroeconomic policies and other factors, combined with our forecast model,
Due to the lack of high-end products, parts and components industry is seriously lagging behind the development of basic, structural overcapacity in the shipbuilding industry issues still outstanding, automobile consumption will remain subject to some constraints, own-brand cars structural overcapacity will continue. China's mold equipment industry growth will slow in the stabilization, which was slow in the raw materials industry overall stabilization of the situation. January to September this year, above-scale industrial added value increased raw material of 10.15%, the annual growth rate of industrial added value up is expected to remain at about 10%. With the slow recovery of the international economy and domestic economic stabilization and recovery, structural recovery in domestic demand growth, the export situation will be eased, production growth will be China's mold industry rebounded slightly. Eastern industrial production growth will continue to slow down, the Midwest will continue rapid growth. From a regional perspective, because the various regions in which the different development stages of industrialization, the growth rate showed a clear differentiation trend, namely the eastern industrial added value was in the low mold growth, central and western regions is growing rapidly, and this trend in 2013 will continue. Accelerate the construction of infrastructure, investment in fixed assets in central and western regions the power of strong first three quarters of 2012, the six central provinces were higher than the national growth rate of investment, including investment of 10 billion half of the provinces. Due to the central and western regions is in the middle of industrialization, investment-driven features are still evident, with greater growth potential and vast room for improvement is expected in 2013 in the central and western regions will die of industrial added value grew by 11.5% and 13%, respectively about.

Microcomputers and mold industry

To efficiently use these tools must also have advanced CAD / CAM software platform, although the hardware, software and the machine itself, the high price and maintenance costs, but due to the use of these technologies, so that these companies can greatly shorten the manufacturing cycle of mold improve manufacturing quality and mold manufacturing capabilities, enhanced in the international market competitiveness. Computer manufacturing precision molds for customers telephone company  fittings mould package (of 7) plastic mold, all sophisticated, complex surface parts, the company uses in engineering workstations running UG secondary development of software and systems to quickly build the entire three-dimensional line deputy dies box model to generate toolpath file formed by post-processing of the NC machining CNC machine code. Quality die from contract signing to delivery, the entire cycle of less than three months, we can see that CAD / CAM technology in the mold manufacturing role of self-evident.
Use development of China's mold industry INTERNET past 10 years, China's mold industry is developing very rapidly, CAD / CAM technology, advanced mold processing equipment and new technology enterprise in many mold has been applied and spread, making the domestic mold design and manufacturing standards continue improved, although some mold on the quality, the domestic enterprises have close to the world advanced level, but our mold companies in production management, manufacturing cycle, quality control, and tapping tee electrofusion mould  other aspects of enterprise scale and efficiency compared with similar companies in developed countries, the gap is still evident.
Mold companies in the information era of global economic integration development, stressing the joint and access and use of information, or the country with the world's large companies conducted a competitive league, learn, and use of these company's experience and market development and grow their own, convert it to their own competitiveness. INTERNET create the necessary conditions and a favorable environment for mold companies to achieve the above purpose.

Link mold production technology and research

Taking a car engine connecting rod example, the technical requirements are: ( 1 ) quenching , HB220 ¯ 270. ( 2 ) did not note the draft angle 3 ° ~ 5 °, did not note fillet R2 ~ R5; (3) the direction of the metal structure of the fiber longitudinal section along the centerline and should match the rod shape , not a disorder and intermittent , allowed to have pores, cracks , folds , bubbles , delamination , inclusion , and other  plastic injection mould non-metallic inclusions and other defects. ( 4 ) does not machined surfaces should be smooth, not allowed to have cracks , folds , scars , and metal oxide is not full and other defects. Residual fly 5 ) parting edge ≤ 0.8mm, allowing total ≤ 3, the width of ≤ 5mm, ≤ pit depth or ground traces 1mm defect repair , but not in the position of the same cross section . ( 6 ) shall be subject to inspection rod . ( 7 ) does not allow forging defects repaired by welding . ( 8 ) the difference in weight of each batch of forging ≤ 3%.
Car engine connecting rod materials are: ( 1 ) quenched and tempered steel , such as 42CrMo, 35CrMo, 45 , etc. ; ( 2 ) non- quenched and tempered steel , such as C70S6 ( one kind of cracking material ) , etc., the surface after the procedure is no longer machining , the surface quality requirements , and this requires a further increase trend. Further, in order to enable smooth operation of the engine to reduce engine noise and power consumption , high tolerance requirements rod weight , generally less than 5% , this requirement also tends to be improved further . These requirements are very high for forging process for manufacturers of production technology is a challenge , not the conventional production process in general forging , otherwise there will be a lot of substandard goods . Car engine connecting rod and die forging process heating equipment: medium frequency induction furnace, oil furnace . Forging equipment: hot forging press , friction press , high-energy screw press , electro-hydraulic forging hammer .
Mold insert commonly used type and is a two- cavity mold that has a beginning and end forging forging two pairs on a mold cavity , generally  2 inch pvc coupling mould use the open slot with a flash form guide for the locking type or guide pins and bushings mold material class H13 tool steel , using conventional heat treatment , hardness HRC40 ~ 47, die life of about 3000 . The above process and die type commonly used in the current general manufacturers , production technology is more mature and stable, but the rod forging quality in general, it is necessary to be improved. Improve the technical requirements of the production of raw materials found in some raw material manufacturers rod car engine does not fully understand the material requirements , treat it as a general view of the thermal processing of steel , there are many problems caused by raw bar, resulting in the bulk of the waste generated .
Therefore, the proposed increase in raw materials inclusions grade requirements in the standard , the inclusion level not higher than 2 , in order to effectively improve the surface and internal quality.
Car engine connecting rod is generally little change in cross-sectional area , can employ cross wedge rolling billet , while the use of roll forging billet billet system will increase the time and the need to increase the mechanical hand and roll forging machine, so that the operation becomes complicated , reduces productivity improved rejection rate. Forging preform rod car engine uses a rotating outer wedge rolling , cross rolling process this principle is to heat billets placed two co-rotating rolls , making the rough turning and molding surface along the corresponding the reduced diameter and extension. Cross wedge rolling billet with high efficiency , saving raw materials and equipment manufacturing and easy . Meanwhile, the rolling line inside the contour line and the part of the flow , thereby improving the mechanical properties of the product . Currently cross wedge rolling billet technology is a mature technology , such as the Beijing Institute of Electrical and other domestic units can be supplied from process analysis, design and manufacture  tapping tee electrofusion mould of equipment to mold a set of technical services to meet the requirements of manufacturers of forging . Many forging equipment available for car engine connecting rod , how to choose depends on the equipment cost and the amount of investment , hot forging press is generally used in more imports expensive, but its movement works slider crank linkage structure principle , a fixed bottom dead center position , while forging forming, mold drop height is fixed, thus forging a high degree of tolerance, so forgings weight tolerance , good product quality. If large choice of investment . The basic choice of domestic friction press , low prices, its motion principle of rotary motion of the flywheel is converted to screw by screw nut up and down movement , the drop height is not fixed mold and blow energy is not accurate and well -oriented performance , resulting in forging height tolerance big , wrong move , so forging weight tolerance , poor product quality, and therefore , should not be optional .

International Mould capital growth in China , although brought capital, technology and advanced equipment, but also to the Chinese domestic mold manufacturers brought pressure intensified market competition. Backward relative to the domestic mold manufacturing level , transnational Mould Group not only has abundant capital , advanced technology , quality equipment and the successful experience accumulated over the years of mold , but by virtue of the employment of China 's relatively low labor cost advantage of the resources in the domestic market mold competition ahead of many domestic mold companies . The private enterprise because of the limitations inherent in , lead to competition in the low-end market in general appear mold mold price war , many mold companies to receive orders at prices below cost to process the mold , low prices brought low quality aggravated disorderly competition in the market and the mold mold materials market , has seriously affected the survival of some mold , which is worthy of our attention in the industry 's business .
It is understood that the EU is the world's largest solar market , the annual energy consumption of the world's solar capacity Bridge Bend mould  6 percent. Most of our country's dependence on exports of photovoltaic products , the annual production capacity of 7 Chengdu sold to the European market. However , since the financial crisis, the world economic recovery has stagnated , countries have emerged in the photovoltaic industry business difficulties , bankruptcy and so on. To snatch the EU market , the countries in the European PV companies playing a fierce price war , German companies have a full range to narrow the price gap with Chinese enterprises, making the price advantage of Chinese PV products gradually lost . Moreover, the Chinese PV companies to kick the European market, due to the importance of the EU market , Chinese PV companies feel the unprecedented crisis. Since then, the government sought to prevent European companies have filed actions .

China mold standardized high-end intelligent development

Standard mold is an important part of the mold , the mold base . It shorten mold design and manufacturing cycles, reduce mold production costs and improve the quality of mold have a very important technical and economic sense . Proven experience of foreign industrial countries , specialized production and commercialization of supply standard mold , which greatly promoted the development of mold industry. According to the International Association Secretary-General Luo Baihui mold , widely used standard parts can shorten the design and manufacturing cycle of 25-40 % ; social work because the user can save homemade standard parts caused by the reduction in raw material and energy waste ; may die CAD / CAM applications , such as the foundation of modern technology ; can significantly improve manufacturing accuracy and performance of the mold. Standard parts are usually made ​​using specialized production than its standard position with the precision and accuracy  will increase by at least an order of magnitude , and to ensure interchangeability and improve the life of the mold , thus contributing to the injection moulds conomic system within the industry , as well as the industrial structure and operating mechanism production management reform , to achieve specialization and large-scale production , and promote the formation and development of standard mold commodity markets. You can say no standard mold of specialization and commercialization , there is no modern mold industry. In recent years, with the rapid development of China's mold industry , standardization, specialization and commercialization mold parts , has a high level , has made considerable progress. Since the establishment of the National Standardization Technical Committee mold 1983, experts on mold standard formulation, revision and review of 90 published a number of criteria , including 22 standard die , plastic mold standard more than 20 items. The release of these standards , implementation, promote technological progress and the development of mold industry , resulting in a significant social and economic benefits . Research , development and production of standard parts are molded depth unfold , both product types , varieties, specifications, or technical level of product performance and quality has improved injection moulding significantly. Luo Hui said that the current level of standardization and application of the mold is still relatively low , less than 30% optimistic estimate , compared with foreign industrial countries ( 70-80 % ) , there is a big gap . Although manufacturers are now producing sales increases every year , but most are small-scale , outdated equipment , backward technology, high cost and low efficiency . Only ordinary SME standard die and mold plastic mold, guide post , guide sleeve, putter, die springs, pneumatic components and other products, a high degree of commercialization , can basically meet the domestic market demand , and some exports . While those with high technological content , advanced structure, excellent performance , high quality, convenient replacement products with personalized, such as ball -locking quick punch and a fixed plate , solid lubrication guides and guide sleeve, wedge body and its parts , high-grade plastic mold standard parts and nitrogen in the main spring and so little domestic manufacturers , and because of lack of funds, technology projects difficult to implement , low productivity , long lead times, supply and demand have become increasingly prominent. Therefore , each year still need to import a considerable amount of mold standard parts from abroad , which accounted for about 3-8 % in the mold of imports. Domestic standard mold in technical standards, technology development, product quality and other aspects , there are still many problems. Such as product standards confusion, less functional elements and low technology content , applicability poor ; small technological efforts , outdated equipment , backward technology, low level of professionalism , product quality is unstable ; lack of professional personnel, poor management, low productivity long lead times ; production and sales outlets are unevenly distributed, operating fewer varieties and specifications , inadequate supply ; certain units in order to compete for the market , do not speak quality , shoddy, shoddy goods flooding the market. There regardless of the cost , the price of blind , disrupt the market phenomenon, is the need to carefully study , Cheng to be solved . Automobile and motorcycle industry is the largest market for mold , household appliances, electronic communications, construction equipment , instrumentation, plastics and rubber industries have considerable mold market . From the perspective of long-term development , China's mold industry will accompany the advent of the knowledge economy era while undergoing profound change, typifying the mold structure , standardized components , standardized supply of specialized production and commercialization , but also the future development an inevitable trend. With the application of the standard mold increasingly widespread in the future market economy standard mold will become a very active but the rapid development of products , Luo Baihui convinced that the development prospects of the standard mold industry is very optimistic and beautiful .
