Compression molding using insulating films |
摘要 |
Deformable insulating films are used as mold liners in a compression molding process. The film delays the initial cooling of the preheated thermoplastic charge. The film also serves as a plastic charge carrier and convection barrier during transport of the plastic charge from a heating unit into the compression molding press.
