Abstract
A multi-injection molded body made of at least a first and a second resin is molded, an undercut is formed generally by pressing a part of the surface about an aperture opening formed in a first molded body made of the first resin to project interior side wall faces of the aperture inward, and injecting a second resin to mold a second molded body in the aperture. The multi-injection molded body thus formed has an undercut in the aperture, so that the second molded body is tightly fixed to the first molded body. A multi-injection molding machine for producing the first and second molded bodies is also provided.
