Abstract
A process is provided for making a fluoroplastic molded-in insert without any supplementary production steps. A predetermined number of polytetrafluoroethylene bearers support a core material apart from the surface of a mold by a space equal to the desired thickness of a surfacing material to be formed on the surface of the core material. After disposing the bearers between a mold surface and the core material, hot-melt fluoroplastics are molded so as to combine the core material, the bearers and the hot-melt fluoroplastics into one unit. As a result, the core material is completely and simultaneously embedded when hot-melt fluoroplastics are molded.
