At present, China's plastic mold industry is becoming larger and larger, and the precision will be higher and higher. 10 years ago, the precision of precision plastic molds was generally 5μm, and now it has reached 2-3μm. Soon, a 1μm precision mold will be available. With the miniaturization of parts and the improvement of precision requirements, the machining tolerances of some molds are required to be less than 1 μm, which requires the development of super finishing.

Experts believe that China's plastic mold industry should further develop multi-functional composite molds. In addition to stamping and forming parts, a multi-functional mold is also responsible for assembly tasks such as lamination, tapping, riveting and locking. This versatile mold is no longer a batch of parts, but a batch of components, such as components of the contacts and bearings, various tiny motors, electrical components and iron core components of the instrument. Multi-color and multi-material plastic forming dies will also develop rapidly. This type of mold shortens the production cycle of the product and will be developed and applied in different fields in the future.

With the increasing application of hot runner technology, the proportion of hot runner molds in plastic molds will gradually increase. Molds using hot runner technology can improve the productivity and quality of the parts, and can greatly save the raw materials of the parts. The application of this technology has developed rapidly in foreign countries and is very common. Domestic hot runner molds have also been produced, and some enterprises have reached about 30%, but in general, the proportion is too low and needs to be developed. With the continuous improvement and development of the plastic molding process, gas-assisted molds and molds adapted to the high-pressure injection molding process will develop.

Relevant experts believe that the application of mold standard parts will become more and more extensive, and the standardization of molds and the application of mold standard parts can greatly affect the mold manufacturing cycle. The use of mold standard parts not only shortens the mold manufacturing cycle, but also improves mold quality and reduces mold manufacturing costs. At the same time, the prospect of fast economic molds is very broad. Since people require molds to have a shorter production cycle, the development of fast and economical molds has attracted more and more attention. For example, various superplastic materials are developed to make molds; simple molds are made of epoxy, polyester or fillers such as metal and glass. This type of mold has a simple manufacturing process, easy control, low shrinkage, low price and high life. Automobile cover moulds can also be made from cement plastic. Medium and low melting point alloy molds, spray molding dies, electroforming dies, precision casting dies, laminating dies, ceramic blister dies and light styling, and the use of heat-hardened rubber to quickly manufacture low-cost molds and other fast economic molds will be further developed. Fast changeover frames, quick-change punches, etc. will also grow. In addition, the rapid die change device and rapid test mode device technology using computer control and robot operation will also be developed and improved.

Experts believe that the proportion of medium-pressure molds in the mold industry will continue to increase. With the development of lightweight products such as vehicles and motors, there is an increasing demand for the number, life and complexity of die-casting molds. With the development of plastic-based steel, plastic-based wood and the precision and complexity of product parts, the proportion of plastic molds will continue to increase, and the accuracy and complexity will increase accordingly.
