Gas assist injection molding, as an innovative injection process, its core lies in the introduction of gas injection molding in the injection process. This technology injects compressed air or nitrogen into the mold cavity while injecting plastic melt through the gas assist injection molding machine, so that the plastic expands under gas pressure and clings to the mold surface, and finally forms an accurate product shape. This mechanism not only significantly improves the dimensional accuracy and quality of injection molded parts, but also effectively eliminates internal bubbles and gray glue, and improves the yield and product quality.
