Gas Assist Injection Molding

<<   Project Examples  >>

Gas Assist Injection Molding technology utilizes the injection of high-pressure nitrogen gas into the molten plastic toward the final phases of the injection molding process. This nitrogen produces coring of the thick sections of the plastic part by displacing the molten material as the nitrogen enters the mold. Results are maximized with proper part designs for the particular application.
