EXTRUSION MOLDING METHOD FOR BRIGHT MOLDING AND REINFORCING BRIGHT FILM APPLIED ON OUTER APPEARANCE SECTION OF THE MOLDING

摘要

PURPOSE:To prevent the blurring of a bright film on an extrusion molded bright molding by using a reinforcing bright film composed of a film for reinforcement stuck and laminated on the outer surface of the bright film. CONSTITUTION:A film 6 for reinforcement of comparatively large strength such as a PE(polyethylene terephthalate) or the like is stuck on the outer face of a bright film 4, or laminating reinforcing bright film 4A is used to extrusion mold a bright molding. At that time, a reinforcing bright film 4A manufactured separately can be used. The film can be manufactured in the preliminary process of extrusion molding by means of a mold or the inner side of the same mold. The material and thickness of the film for reinforcement are set in compliance with the actual conditions. The thickness of the reinforced film 6 is roughly 12-17mum, while the whole thickness of the reinforced bright film 4A is approximately 300mum.
