MULTI-INJECTION MOLDED BODY, A METHOD OF MOLDING FOR THE SAME, AND A MULTI-INJECTION MOLDING MACHINE

摘要

In the present invention, when a multi-injection molded body made of at least a first and a second resins is molded, catching means is formed by wall of a concave section of a first molded body with steps of forming the undercut section in the concave section by pressing the rim of concave section formed in the first molded body made of the first resin to project the wall faces of the concave section toward inside thereof, and injecting the second resin to mold a second molded body in the concave section. The multi-injection molded body has catching means in the concave section, so that the second molded body is tightly fixed to the first molded body.
