Deep Analysis: Ten Development Trends of Mould Hardware in China

China has gradually become a major hardware processing and exporting country in the world, and has become one of the major hardware producing countries in the world, with broad market and consumption potential. Mold hardware is also an important part of China's hardware industry. The "Twelfth Five-Year Plan" period is a crucial period for China to properly cope with major changes in the development environment at home and abroad and accelerate the goal of building a well-off society in an all-round way. It is also a crucial period for the healthy development of China's mold manufacturing industry. Although there are many uncertain factors at home and abroad, However, China's economic development is still in the period of rapid growth, the comparative advantage of China's 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 precision of the mold is getting higher and higher. Ten years ago, the precision of precision molds was generally 5 microns, but now it has reached 2~3 microns, and molds with 1 micron precision will be listed soon. This requires superfinishing.

Second, the mold is becoming larger and larger. This is caused by the development of "multi-cavity in one mold" due to the increasing size of parts molded by molds and the requirement of high production efficiency. Nanjing screw

Third, the multi-functional composite mold will be further developed. In addition to stamping parts, the new multifunctional compound die also undertakes assembly tasks such as laminating, tapping, riveting and locking, which requires higher and higher performance of steel.

Fourth, the proportion of hot runner mold in plastic mold is gradually increasing. Because the hot runner technology can improve the productivity and quality of parts and greatly save raw materials, the application of hot runner technology has developed rapidly in foreign countries. More than half of the plastic molds produced by many plastic mold factories use hot runner technology, and the utilization rate of some manufacturers reaches over 80%, with obvious effects. Hot runner molds have also been produced in China, and the utilization rate of some enterprises has risen to 20%~30%.

Fifth, with the continuous improvement and development of plastic molding technology, gas-assisted molds and molds suitable for high-pressure injection molding will develop accordingly. This kind of die requires good rigidity and high pressure resistance, especially the cavity of precision die should be quenched, the gate should be sealed well and the die temperature can be accurately controlled, so the performance of die steel is very strict.

Sixth, the application of standard parts will be more and more extensive. Mould standardization and the application of mould standard parts will greatly affect the mould manufacturing cycle, and can also improve the quality of mould and reduce the mould manufacturing cost. Therefore, the application of mold standard parts will be greatly developed during the Tenth Five-Year Plan period.
