In gas-assisted injection molding the mold is partially filled with polymer, followed by a gas, which presses the polymer out to the surface of the mold, resulting in a hollow part. This process can be used for producing lighterweight parts, often with reduced cycle times as a result of less material to cool. Thickwalled parts can be produced with fewer surface imperfections, such as sink marks, but equipment costs will be higher. Figure 1.25 shows the gas-assist injection molding method.
