China plastic mold industry, the direction of development - Ultra-precision machining
Plastic mold forming workpiece to demonstrate its high accuracy, high complexity, high consistency, high productivity and low consumption, plastic mold manufacturing method has its own unique value creation. Plastic mold to a large extent determines the product quality, efficiency, and development capabilities.
Some industry experts believe that with the plastic mold industry in China increasingly large-scale, precision, will also 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 plastic mold machining precision tolerance requires the following in the 1μm, which requires the development of ultra-precision machining.
Experts believe that China's plastic 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. Multi-color and multi-material plastic molding mold will also have rapid development. The plastic mold shorter production cycle, in the future will be developed in different fields and applications.
China Plastic Mold with hot runner technology, the growing network to promote the application of hot runner molds in the plastic mold will gradually increase the proportion. Plastic mold with hot runner technology can improve productivity and quality of the workpiece, and the workpieces can also save raw materials, the technology used in foreign countries has developed rapidly. Domestic hot runner mold has also been produced, there are some companies has reached about 30%, but from the overall point of view, the ratio is still low, yet to be developed.
Experts believe that China's net plastic mold, plastic mold 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 continuous improvement, the proportion of plastic mold will continue to improve its accuracy and complexity will also be along with a corresponding increase.
