China has gradually become a major hardware processing country and a major export country in the world, and has become one of the world’s major hardware production countries. It has a broad market and consumption potential. Mold hardware is also an important part of China’s hardware industry. The "Twelfth Five-Year" period is China’s proper response. The critical period for major changes in the development environment at home and abroad and for accelerating the realization of the goal of building a well-off society in an all-round way is also a critical period for the healthy development of China’s mold manufacturing industry. Although there are many environmental uncertainties at home and abroad, China’s economic development is still in a period of rapid growth. The comparative advantages of molds in the international mold market still exist, and the domestic mold market is expected to continue to be optimistic, and the mold industry is showing 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, and now it has reached 2 to 3 microns, and molds with a precision of 1 micron will be on the market soon. This requires super finishing.

The second is that the mold is becoming larger and larger. This is caused by the development of "one mold with multiple cavities" due to the increasing size of mold parts and high production efficiency requirements.

The third is that the multi-functional composite mold will be further developed. In addition to stamping and forming parts, the new multi-functional composite mold also undertakes assembly tasks such as lamination, tapping, riveting and locking, and the performance requirements of steel are also getting higher and higher.

Fourth is the gradual increase in the proportion of hot runner molds in plastic molds. Because molds using hot runner technology can improve the productivity and quality of parts, and can 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 heat flow Dao technology, the utilization rate of some manufacturers has reached more than 80%, and the effect is very obvious. Hot runner molds have also been produced in my country, 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 that adapt to high-pressure injection molding processes will develop accordingly. This type of mold requires good rigidity and high pressure resistance, especially the precision mold cavity should be quenched, the gate sealing 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 increasingly widespread. The application of mold standardization and mold standard parts will greatly affect the mold manufacturing cycle, and can also improve the quality of the mold and reduce the cost of mold manufacturing. Therefore, the application of mold standard parts will surely get greater development during the "Tenth Five-Year Plan" period.

Seven is the prospect of rapid economic mold is very broad. Now is the era of multi-variety and small-batch production. In the 21st century, this mode of production will account for more than 75% of industrial production. Therefore, on the one hand, the product life cycle is shortened, and on the other hand, the pattern changes frequently, and the mold production cycle is required to be as short as possible. Therefore, the development of rapid economic molds will attract more and more attention.

Eighth, with the development of lightweight products such as vehicles and motors, the proportion of die-casting molds will continue to increase, and at the same time, higher and higher requirements for the life and complexity of die-casting molds will be put forward.

Ninth, mold technology content will continue to increase, and the proportion of medium and high-end molds will continue to increase. This is also a change in the mold market trend caused by product structure adjustments.

10 The process of replacing steel with plastic and wood with plastic is further accelerated, and the proportion of plastic molds will continue to increase. At the same time, due to the continuous improvement of the complexity and precision of mechanical parts, the requirements for plastic molds are also getting higher and higher.
