Luo Baihui: China's plastic molds are developing towards ultra-precision machining

Luo Baihui believes 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. Multi-color and multi-material plastic forming dies will also develop rapidly. This plastic mold shortens the production cycle of the product and will be developed and applied in different fields in the future.

Luo Baihui pointed out that with the increasing application of hot runner technology, the proportion of hot runner molds in plastic molds will gradually increase. Plastic molds using hot runner technology can improve the productivity and quality of the parts, and also save the raw materials of the parts. The application of this technology has developed rapidly in foreign countries. Domestic hot runner molds have also been produced, and some enterprises have reached about 30%, but in general, the ratio is still very low and needs to be developed.

Luo Baihui believes that the proportion of medium-pressure molds in the plastic 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.

Plastic mold-formed parts exhibit high precision, high complexity, high consistency, high productivity and low consumption. The processing and manufacturing methods of plastic molds have their unique creative value. Plastic molds largely determine the quality, efficiency and development capabilities of the product. Luo Baihui, an expert in the mold industry, pointed out that as China's plastic mold industry becomes larger and larger, the precision will be higher and higher.
