experts recently in an interview analysis, China’s mold industry will be large, sophisticated, complex, high efficiency, long life and multi-direction.

At present, the electronics, automobile, electrical machinery, electrical appliances, instruments, meters, home appliances, communications and military products, 60% -80% of the parts depend on the mold shape. Molding of the workpiece with demonstrated high accuracy, high complexity, high consistency, high productivity and low consumption, other manufacturing methods can not match. Mold to a large extent determines the product quality, efficiency, and development capabilities.

Experts believe that China’s mold industry will become increasingly large, and the accuracy will be getting higher and higher. 10 years ago, the accuracy of precision molds generally 5μm, now stands at 2-3μm. Soon, 1μm precision molds will be available. With the miniaturization of components and precision requirements increase, and some mold machining precision tolerance requires the following in the 1μm, which requires the development of super-finishing.

Experts believe that China’s mold industry to further develop multi-functional composite die, a set of multi-die press forming parts in addition, also responsible for layers, tapping, riveting, and assembly tasks such as locking. Through this multi-functional out of the mold is no longer produced bulk parts, but the bulk of the components, such as contact with the bearing components, a variety of small motors, electrical and instrumentation of the core components. Multi-color and multi-material plastic molding mold will also have rapid development. This reduces the production mold cycle, the future will be developed in different areas and applications.

With the growing popularization and application of hot runner technology, hot runner molds in the plastic mold will gradually increase the proportion. Use of hot runner technology, the mold can improve productivity and quality of workpiece, and can greatly save workpieces of raw materials, the application of this technology has developed very rapidly in foreign countries has been very common. Domestic hot runner mold has also been produced, some enterprises has reached about 30%, but, in general, the ratio is too low, yet to be developed. With the plastic molding process of continuous improvement and development of mold and adapt to the high-pressure gas-assisted injection molding process will follow the development of mold.

Relevant experts believe that mold standard parts of the applications will be increasingly wide range of standard die and mold standard parts of the applications can greatly affect the mold manufacturing cycle. The use of mold standard parts can not only shorten the mold manufacturing cycle, but also to improve quality and reduce mold mold manufacturing costs. At the same time, rapid economic mold enjoy broad prospects. Because people asked mold production cycle as short as possible, so development of rapid economic die has drawn increasing attention. Such as the development of various superplastic materials, to produce mold; use epoxy, polyester, or in which the filling of metal, glass and other materials to enhance production of simple mold. Such mold manufacturing process is simple, precision, easy to control, less shrinkage, low price, a higher life expectancy. Can also be made with cement plastic auto panel dies. , The low melting point alloy mold, mold spray, electric molds, precision molds, stack mold, Plastic mold ceramic modeling and the use of light and heat curing rubber molds and other low-cost, rapid manufacturing will be further development of rapid economic mold. Quick-change die frame, quick-change red top will also be growing. Another use of computer control and mechanical hand-operated quick change die equipment, rapid test-mode device technology will be developed and improved.

experts believe that die-casting mold industry, the ratio will continue to increase. As the vehicles and lightweight motor and other products to develop in the direction of the die-casting mold number and complexity of life will make increasing demands. Along with the plastic on behalf of the steel, plastic and wooden parts of the development and product precision and complexity of the continuous improvement, the proportion of plastic mold will continue to improve its accuracy and complexity will also be along with a corresponding increase.
