Latest Patents

Yiping Ma holds a patent for a method of improving the appearance of injection molding and foaming products. This method involves closing the moving mold and the fixed mold while applying a clamping force. A mold cavity is formed between the two molds, which is then inflated with high-pressure and high-temperature gas. The process continues until the air pressure in the mold cavity reaches between 2-25 MPa, with the gas temperature ranging from 60-200°C. Molten resin containing a foaming agent is injected into the mold cavity while maintaining the inflation of the gas. After the injection is complete, the inflation is stopped, and pressure is released by opening the mold.
