China has gradually become a major hardware processing and exporting country in the world, and has become one of the world''s major hardware manufacturers, with a vast market and consumer potential, mold hardware is also an important part of China''s hardware industry, the "Twelfth Five-Year" period is China''s proper response The key period for the development of major changes in the environment at home and abroad and the acceleration of the goal of building a well-off society in an all-round way is also a crucial period for the healthy development of China''s mold manufacturing industry. Although there are many environmental uncertain factors at home and abroad, China''s economic development is still in the period of rapid growth. The comparative advantage of molds in the international mold market still exists, and the domestic mold market is expected to continue to be optimistic, and the development of the mold industry presents a general trend.
First, the accuracy of the mold is getting higher and higher. 10 years ago, the precision of precision molds was generally 5 microns, and now it has reached 2 to 3 microns, and soon 1 micron precision molds will be available. This requires super finishing.
Second, the mold is becoming larger and larger. This is caused by the "multiple cavities" developed by the increasing size and high productivity requirements of mold-formed parts.
Third, the multi-functional composite mold will be further developed. In addition to stamping and forming parts, the new multi-functional composite molds are also responsible for assembly tasks such as lamination, tapping, riveting and locking, and the performance requirements for steel are also increasing.
Fourth, the proportion of hot runner molds in plastic molds is gradually increasing. Since the molds using hot runner technology can improve the productivity and quality of the parts and greatly save the raw materials for production, the application of hot runner technology is developing rapidly in foreign countries. Many plastic molds produced by plastic mold factories use heat flow more than half. Road technology, some manufacturers use more than 80%, the effect is very obvious. Hot runner molds have also been produced in China, and some enterprises have increased their usage rate to 20% to 30%.
Fifth, with the continuous improvement and development of plastic molding processes, gas-assisted molds and molds suitable for high-pressure injection molding will develop. Such molds require good rigidity and high pressure resistance, especially the cavity of the precision mold should be quenched, the gate sealing property is good, and the mold temperature can be accurately controlled, so the performance requirements of the mold steel are very strict.
Sixth, the application of standard parts will become more and more extensive. Mold standardization and the application of mold standard parts will greatly affect the mold manufacturing cycle, and also improve the quality of the mold and reduce the cost of mold manufacturing. Therefore, the application of mold standard parts will be greatly developed during the "10th Five-Year Plan" period.
