Abstract

A process for simultaneously coating and forming a body. The process includes moving two mold halves into contact with one another; introducing an injection-molding material into the mold halves so that a molding is formed; evacuating the molding; admitting a gas into the molding; igniting a plasma in the molding so that a coating is deposited on the inner side of the molding; and moving the mold halves apart so that the molding drops out.
