Gas-Assist Injection Molding: When and Why to Use It

Gas-assist injection molding injects nitrogen gas into the mold during the injection cycle, creating hollow sections or applying pressure to reduce sink marks. Benefits include: reduced part weight (20-50% savings), elimination of sink marks on thick sections, improved dimensional stability, and shorter cooling times. Common applications: automotive handles, appliance panels, thick-wall structural components.
