Gas assist injection molding is a low-pressure process utilizing nitrogen gas to apply uniform pressure throughout the molded plastic part.

By displacing molten plastic from thicker sections of the part toward areas in the cavity that are last to fill, nitrogen gas pressure creates channels within the part. Through the gas channels, pressure is transmitted evenly across the part eliminating warping, sink marks and internal stress.

As a result, reductions in clamp tonnage, cycle time and part weight are realized while the strength and rigidity of the part is increased.

Gas assist allows molders the freedom to design plastic parts without restrictions and limitation inherent to conventional molding.
