The use of Injection Molding forming technology components have certain adaptability, it requires relatively thin, also has a certain shape. Components has thickness and diameter like crankshaft, connecting rod is difficult to use mold stamping. Now the most can be used is using mold embryo, and then use cutting for Precision Machining.
The accuracy of the mold will be higher and higher. In the electronics, automotive, instrumentation, home appliances, 80%-90% parts are relying on mold forming, the shape of the mold or plastic mold determines the products shape, the same to the quality. With the economic and living standards rising, the number of cars also rise. China’s mold industry led the development of the automotive industry.
