In recent years, with the rapid development of electronic information industry and information technology transformation , the prospect of a vast plastic mold market , the world's high-grade , precision plastic mold market is in short supply situation of traditional industries.
The weight of a single set of plastic mold manufacturing level has been greatly improved, the production of Coupler mould large plastic mold has reached more than 50t , the accuracy of precision plastic mold has reached 3cm, multi-cavity plastic molds capable of producing plastic mold cavity of a mold 7800 , high-speed extrusion molds capable of producing more than the speed of high-speed 4m/min plastic profile extrusion dies and coextrusion die lumen main sections . With the continuous improvement of the rapid development of the plastics industry and general engineering plastics in terms of intensity , scope of application of plastic products is also expanding , the amount of plastic products is on the rise . It is understood that China 's output of plastic products in 2012 nearly 60 million tons , and continues to tapping tee electrofusion mould grow process, we can see that domestic demand for China's plastic mold industry has a huge impetus.
In recent years, according to the International Association of mold , the mold industry associations to actively encourage member companies to update technology and equipment , to promote the technology and product innovation , and guide qualified enterprises from production processes to develop , expand sales of high value-added mold , injection mold manufacturing have a new large-scale expansion. Regional and national distribution of plastic processing industry is similar to the Pearl River Delta , Yangtze River Delta plastics processing industry forefront , Zhejiang, Jiangsu and Guangdong, the Shorter Pipe Clip proportion of the national output of plastic mold mold output value also accounted for 70 %. With the Chinese automotive, appliance, electronic communications , the rapid development of various building materials, is expected to die in the future market, accounting for the total amount of plastic mold will gradually increase the proportion of mold , and the growth rate will be faster than other mold.
The mold is used to shape the article tool that constitute various parts of different parts of the mold by a different composition. It is mainly formed by changing the physical state of the material to achieve the shape of the article processing. In blanking, forming stamping, forging, cold forging, extrusion, compression molding or injection molding powder metallurgy processing repression
