Air Assist

Air Assist is a type of plastic injection molding service in China used to improve part quality, surface texture, and material usage. It is done by injecting highly pressurized nitrogen gas through the tool during the injection process. The result is less wear and tear on the tool and a smoother plastic part. We recommend this service when making plastic parts that are bigger or thinner than usual industry standards.
