INJECTOR FOR IN-MOLD COATING METHOD AND IN-MOLD COATING METHOD

摘要

PROBLEM TO BE SOLVED: To improve precision in treatment of an in-mold coating method by a method wherein injection pressure in an injector is raised, and a trace quantity can be measured. SOLUTION: A measuring cylinder 2 measuring coating flux is connected to an injection cylinder 1 equipped with a coating flux injection piston 3. The injection cylinder 1 and the measuring cylinder 2 are integrally constituted, which constitute an injector for in-mold coating method. Since the measuring cylinder 3 and the injection cylinder 1 are integrally mounted to the injector, the measured coating flux is accurately fed to the injection cylinder 1 without generating errors. Further, since the coating flux is injected by the injection piston 2, high pressure injection can be carried out.
