At present, the plastic mold in the mold industry, which accounts for the proportion is about 30%, in the mold of import and export in the proportion as high as 50 ~ 70%. in recent years, China's rapid development of plastic mould. The increasingly widespread application of plastics, provides a very broad market for plastic mould.
In addition, China plastic mould in the promotion of high technology driven and pillar industry of application requirements, formed a huge industrial chain, from upstream raw materials industry and processing, testing equipment to the downstream machinery, automobile, motorcycle, household appliances, electronic communication, building material and so on several applications for industry, plastic mold the development of a life.
At the same time, construction, household appliances, automobile and other industries demand for plastics are great. According to estimates, only the automobile, motorcycle industry every year need plastic mold about 10000000000 yuan, there are also about 2800000000 yuan a year market TV plastic mould. Know, mold market is stable overall warming up, in the future market of the mold, plastic mold growth rate will be higher than other mold in the mold industry, the proportion will gradually increase.
The development trend of plastic mould processing technology
(1) the high productivity of molding parts increasingly large-scale and parts requirements of multi cavity mold, causing mold is large, large tonnage of large mould of up to 100 tons, a mold cavity, hundreds of thousands of cavity mold processing equipment, require large working table, increase the Y axis and Z axis travel, large bearing, high rigidity, high consistency.
(2) die steel mold processing requirements of high hardness, mold processing equipment has thermal stability, high reliability.
(3) of complex cavity and multi-functional composite mold, with complex shape of parts, must improve the level of mold design and manufacturing, multifunctional composite mould a plurality of groove, a variety of material forming or assembled into components in a mold, requires large amount of processing programming, has profound cavity machining ability and high stability, increase the difficulty of processing.
(4) fine mold processing of the composite, high efficiency machining equipment more attention. High speed milling can be processing high hard materials, machining, cutting force is small, the workpiece heating has many advantages of small deformation of the die enterprises pay more attention to the high speed machining.
(5) the high dynamic accuracy. Machine tool manufacturing enterprises introduce static performance in the mold three-dimensional surface machining, can not reflect the actual situation of processing. Three dimensional surface high precision mold processing, more proposed the accuracy performance of high dynamic requirements of high speed and high precision machine tool, but also in the high rigidity, thermal stability, high reliability and high quality control system can realize the matching.
China is the world's manufacturing center, manufacturing power hardware die casting industry, after years of rapid development of China's hardware to the casting mold industry market prosperity, but the market for high-end products or defects, regardless of quality, roughness, accuracy and structural aspects of an international first-class products has not short distance.
China mold manufacturing industry through years of development, the mold industry, the production cycle is higher than the international level, but the product level is relatively low. Luo Baihui thinks, this is mainly due to the casting mold precision, cavity surface roughness, life and structure etc.. At present, China's foundry mold enterprise technical personnel ratio low, levels were also lower, and do not attach importance to product development, often in a passive position in the market.
With China's sustained economic growth, casting industry will remain high growth and promote the development of casting mould manufacturing industry, casting mould market unusually active, because our country mould production cost is relatively low, with the perfection and quality of mould manufacturing technology
