China's plastic mould technology has gradually expanded the market
At present, plastic molds account for about 30% of the whole mold industry, and the proportion in the mould and export is as high as 50 ~ 70%. In recent years, plastic mold has developed rapidly in China. The application of plastic products is becoming more and more extensive, providing a very wide market for plastic mould.
In addition, China plastic mould in high technology driven and pillar industries driven application requirements, formed a huge industry chain, from upstream raw material industry and processing, testing equipment to the downstream machinery, automobiles, motorcycles, home appliances, electronic communication application and so on several big industry, building materials, plastic mold development vitality.
Meanwhile, the demand for plastics in construction, home appliances and automobiles is high. It is estimated that the auto and motorcycle industry alone needs more than 10 billion yuan of plastic molds each year, and the plastic moulds of plastic moulds are about 2.8 billion yuan each year.
, the overall of mould market is steadily upward, in die market of the future, the development of plastic mold speed will be higher than other mold, the proportion will gradually increase in the mold industry.
Development trend of plastic mould processing technology
(1) molding parts of increasingly large and parts of the high productivity requirements more than a mold cavity, the increasingly large mould, large-tonnage big mould can reach 100 tons, a die hundreds, thousands of cavity, the cavity mould processing equipment big worktable, increasing y z axis distance, bearing, high rigidity, high consistency.
(2) high hardness of die steel material, and the requirement of thermal stability and high reliability of die processing equipment.
(3) for complex cavity and multifunctional composite mould, as parts of complicated shape, must improve the level of mould design and manufacture of a variety of groove, a variety of material in a mold forming or assemble components of multifunctional composite mould, requires large amount of processing programming procedures, with comprehensive Gao Shenkong cavity cutting ability and high stability, improve the processing difficulty.
(4) the refinement of die processing makes the complexity and efficiency of the processing equipment more interesting. High speed milling has many advantages such as high machining hard material, smooth machining, small cutting force and small temperature distortion of workpiece, which make the mould enterprises pay more and more attention to high speed machining.
(5) high dynamic accuracy. The static performance of machine tool production enterprises can not reflect the actual machining situation when the die is processed in 3d surface. Of 3 d surface mold precision machining, puts forward the requirement of high precision dynamic performance, high speed and high precision but also in the machine tool of high rigidity, high thermal stability, high reliability, and quality control system of combination become possible.
Our country is the centre of the world's manufacturing, metal casting die &mold manufacturing power, after years of rapid development hardware casting mould industry in our country market to flourish, but high-end products on the market or defect is very big, whether it's quality, roughness, accuracy or structure is an international first-class products with short distance.
China's mold manufacturing industry has experienced years of development, the mold industry production cycle is higher than the international level, but the product level is relatively low. This is mainly due to the precision of casting mould, roughness, life and structure of the cavity surface. At present, the proportion of technical personnel of casting mould enterprise in our country is low, the level is low, and the product development is not emphasized, and the market is often in the passive position.
Along with our country economy keep growing, casting industry will maintain rapid growth and accelerate the development of casting mould manufacturing industry, casting mold market active, because our country mold production cost is low, with the improvement of the mold manufacturing technology and the improvement of quality. Not only can we reduce the import of mould, but also may gradually open the foreign market, mold export will have a great development.
