1. The mold is becoming larger and larger. This is caused by the development of ", the multi cavity " of mould, because of the increasingly large size and high production efficiency of moulded parts.
2. 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 1 micron accuracy will be available soon. This requires ultra-finishing.
3. It is the multifunctional composite mold that 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 for steel are also increasing.
4. the proportion of hot runner molds in plastic molds has gradually increased. Since hot runner technology can improve the productivity and quality of the parts, and can greatly save the 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, some manufacturers use more than 80%, the effect is very obvious. Hot runner molds have also been produced in China, and the utilization rate of some enterprises has risen to 20% ~ 30%.
5. with the continuous improvement and development of plastic molding technology, gas-assisted molds and molds adapted to high-pressure injection molding and other processes will be developed with them. This type of mold requires good rigidity and high pressure resistance, especially the cavity of the precision mold should be quenched, the sealing of the gate is good, and the mold temperature can be accurately controlled.
6. Standard parts will be widely used. Mold standardization and the application of mold standard parts will greatly affect the mold manufacturing cycle, and improve the quality of mold and reduce the cost of mold manufacturing. Therefore, the application of mold standard parts will get a great development in the period of the tenth five-year plan.
7. 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 production method will account for more than 75% of industrial production. Therefore, on the one hand, the product use cycle is shortened, and on the other hand, the pattern changes frequently, and the shorter the production cycle of the mold, the better. Therefore, the development of rapid economic mold will attract more and more attention.
8. with the development of lightweight products such as vehicles and electric motors, the proportion of die-casting molds will continue to increase, and at the same time, the life and complexity of the die-casting molds will be increasingly demanded.
9. the process of replacing steel with plastic and wood has accelerated, and the proportion of plastic molds will continue to increase. At the same time, due to the increasing complexity and precision of mechanical parts, the requirements for plastic molds are also increasing.
10. The technical content of molds will continue to increase, and the proportion of medium and high-end molds will continue to increase. This is also the change in the mold market trend caused by product structure adjustment.
