Abstract
After a thermoplastic synthetic resin has been injection molded onto a transfer plate in a thermoplastic injection mold, the transfer plate is shifted into a silicone injection mold maintained at a high temperature and a silicone member is injection molded onto the thermoplastic member. The heat transfer to the thermoplastic body is minimized by, for example, providing insulating material between heated portions of the mold system and other portions thereof and/or by maintaining air gaps from which the silicone is excluded between the thermoplastic member and heated portions of the silicone injection mold.
