China's mold industry to further develop multi-function composite molds -

China's mold industry to large, sophisticated, complex, high performance, long life, and multi-functional direction. At present, electronics, automotive, electrical, appliances, equipment, instruments, home appliances, communications and military products, 60%-cent part, relies on the molding. Mould forming parts of the high-precision, high complexity, high uniformity, high productivity and low consumption, is unmatched by other manufacturing methods. Mold is to a large extent determine the quality of the product and the benefits and development capabilities.

China's mold industry increasingly large, and accuracy will be getting higher and higher. 10 years ago, the precision tooling precision is normally 5 μ m, has now reached 1 μ m. As part of micro and precision requirements increase, some Mold Machining accuracy tolerances required in the 1 μ m, this will strive for the development of super finishing.

China's mold industry to further develop multi-function composite mould, a multifunctional addition stamping parts, mold, also carried stacks of pressure, tapping, riveting and Assembly tasks, such as locking. This versatile die are no longer mass produced parts, but groups of components, such as contact and support components, micro motor, electrical equipments and meters of core components. Multiple colors and materials plastic forming mold will have a faster development. This mold shortens the production cycle of the product, will be developed and applied in various fields in the future.

With the increasing application of hot runner technology, hot runner mould plastic mould's share will gradually increase. Adopt hot runner technology of die and mold can improve the productivity and quality of products, and can greatly save parts of the raw materials, the application of this technology in development abroad, has been widespread. Domestic hot runner molds are manufactured, some enterprises has reached about 30%, but overall, the ratio is too low, needs to be developed. With the continuous improvement and development of plastic forming technology, gas assisted moulds and high pressure injection forming technology of mould will develop.
