In the future, my country’s molds will present ten major development trends:
- 1: Moulds are becoming larger and larger. This is caused by the “one mold with multiple cavities” that requires the development of “one mold and multiple cavities” that require the development of high production efficiency and the increasing size of parts formed by molds.
- 2: The precision of the mold will become higher and higher. The precision of precision molds 10 years ago was generally 5 microns, and now it has reached 2-3 microns, and molds with a precision of 1 micron will be on the market soon. This requires super finishing. To
- 3: Multifunctional composite molds 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 requires higher and higher performance of steel. To
- 4: The proportion of hot runner molds in plastic molds will also gradually increase. Because molds using hot runner technology can improve the productivity and quality of parts, and can greatly save the raw materials produced, 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 my country, and the utilization rate of some enterprises has risen to 20%-30%. To
- 5: With the continuous improvement and development of plastic molding processes, gas-assisted molds and molds suitable for 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 strong. To
- 6: 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 a greater development during the “Tenth Five-Year Plan” period. To
- 7: The prospect of rapid economic molds 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, on the other hand, the pattern changes are ordinary, and the production cycle of the mold is required to be as short as possible. Therefore, the development of rapid economic molds will attract more and more people’s attention and attention. To
- 8: As products such as vehicles and motors move toward lightweight development, 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. To
- 9: 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 getting higher and higher. To
- 10: The technical content of molds will continue to improve, and the proportion of medium and high-end molds will continue to increase. This is also a change in the trend of the mold market caused by product structure adjustments
