    Details:

    When nitrogen gas is injected into the hollow channel of a plastic part or a mold cavity, the endothermic reaction instantly chills the warmer polymer areas inside, so the part can smoothly eject from the mold in less time. High-pressure inert nitrogen gas can push the melt into the cavity for more complete mold filling as in “short shot” applications, or be used to quickly form the gas channel inside hollow parts such as handles, which we call “inner cooling.” Wall thicknesses of tubular-shaped parts are usually thick but homogeneous, and rapid cooling from the inside out can improve cycle times and help eliminate production bottlenecks.

    What Is Gas-Assisted Injection Molding

    In this process, the pressurized gas is injected into the mold cavity through a runner or other designed gas channels during the polymer filling phase. The gas cores out a network of hollow channels and drives the polymer melt to form a part. This process is primarily developed for hollow plastics, thin wall structure with ribs, separate internal void space or channels, etc.
