Gas-assisted injection molding technology injects high-pressure gas into the mold cavity to push the melt forward, delivering significant advantages in weight reduction, sink mark elimination, and internal stress reduction. However, this process demands extremely precise parameter matching, and several typical defects frequently occur in actual production.
