China\'s mold industry should be to the high-end development

Author: ComeFrom:China Wikipedia Date:2016-06-15 20:12:45 Hits:1511
      At present, China's mold industry is becoming larger and larger, and the accuracy will be higher and higher. 10 years ago, the precision mold is generally 5 m, and now has reached 2 - 3 mu m. Soon, 1 m precision mold will be listed. With the miniaturization and precision of parts of the requirements of the increase, some mold processing accuracy of tolerance is required in the following 1 m, which requires the development of ultra precision machining.
       Experts believe that China's mold industry to further develop multi-functional composite mold, a set of multi die stamping parts in addition, responsible for lamination, tapping, riveting and locking assembly tasks. Through this kind of multi function mold production is no longer the bulk parts, but the bulk of components, such as contact with the bearing components, a variety of micro motor, electrical and instrumentation core components, etc.. Multi color and multi material plastic mold will also have a rapid development. This mold shorten the production cycle, in the future will be developed in different areas and applications.
       With the application of hot runner technology, the proportion of hot runner mold in plastic mold will be increased gradually. The mold with hot runner technology can improve the productivity and quality of parts, and can greatly save the raw materials of parts, the application of this technology in foreign countries has developed rapidly, it is very common. Domestic hot runner mold has also been produced, some enterprises has reached about 30%, but overall, the ratio is too low, should be developed. With the continuous improvement and development of plastic molding process, the development of gas assisted mold and the mold to adapt to high-pressure injection molding process will be developed by Sui Zhi.
      Relevant experts believe that the application of mold standard parts will become increasingly widespread, the application of die and mold standard parts can greatly affect the mold manufacturing cycle. Using the mold standard parts can not only shorten the mold manufacturing cycle, but also can improve the quality of the mold and reduce the manufacturing cost of the mold. At the same time, the prospect of rapid economic mold is very broad. Because people require the mold production cycle is shorter the better, so the development of rapid economic mold is more and more people's attention. For example, the development of a variety of superplastic materials to produce mold; with epoxy, polyester or in which filler metal, glass and other reinforced materials for the production of simple mold. This kind of mold manufacturing process is simple, the precision is easy to control, the shrinkage rate is small, the price is cheap, the life is higher. Can also be used to make cement plastic automobile panel die. The low melting point alloy mold, mold spray, electrical mold, casting, stack mold, ceramic mold and plastic optical modeling and use heat curing rubber rapid manufacturing mold and low cost etc. rapid economic mold will be further developed. Quick mold, quick change punch will also be growing. In addition, computer control and mechanical manual operation of the rapid die changing device, rapid test mode device technology will be developed and improved.
        Experts believe that the casting mold industry will continue to increase the proportion of. With products such as vehicles and motor to develop in the direction of lightweight, die-casting mold number and complexity of life will present more and more high requirements. With the development of plastic substitute steel, the development of plastic and the precision and complexity of the products, the proportion of plastic mold will be improved, and the accuracy and complexity will be increased accordingly.
