In the gas assist molding process, the plastic mat erial is melted and injected into the mold cavities via the conventional plastic injection molding process. Plastic material in contact with the mold walls begins to solidify first. As this happens, nitrogen gas is injected into the mold through strategically designed and placed gas channels, providing pressure that pushes the plastic material into the mold extremities.

Once the plastic cures, the nitrogen is vented and the gas assist injection molded plastic parts are removed from the mold. Gas assist injection molding process animation.

Advantages includes:

Less plastic material needed (material saving


Reduced part weight (in some cases up to 40%)

Decreased cycle time

Increased part strength and rigidity

Reduced warpage and distortion

Improved part appearance (eliminates sink marks and surface blemishes)

Reinforces ribbed parts

Increased design options for complex parts, reducing multiple part assemblies, and metal to plastic conversions
