Gas-assisted injection molding is a new type of plastic injection molding that has emerged since the 1990s. It uses high-pressure inert gas to push the melt to fill the cavity, and through gas pressure maintenance, a hollow section is formed inside the thick wall of the plastic part, which can reduce the clamping force, improve production efficiency, and eliminate shrinkage marks on the surface of the plastic part. It is for plastic parts with uneven wall thickness that cannot be injected once, and for the processing of plastic products such as automobiles and home appliances. It has opened up a new application field and is known as an epoch-making revolutionary technology in the Gas-assist Injection Molding process.
