This process involves the injection of plastic into a mould cavity, as with all other injection moulding processes. However, as part of the injection cycle, gas is injected into the cavity at specific points to create voids in the moulding without the use of inserts or cores.

Gas Assisted Injection Moulding can produce internal cavities and eliminate sinking - without the need for complex cores.

This therefore has a significant benefit over "Conventional Injection Moulding" as the mould surface can be uncomplicated in terms of its geometry yet still produce highly complicated internal structures inside an injection moulded component. Nitrogen gas is typically injected during the moulding cycle.
