Abstract

The insert includes a thermoplastic mounting portion which is fused with the thermoplastic material of the body. The insert is maintained in a spaed position from the opening during the heating portion of the molding cycle and positioned within the opening while the thermoplastic material is still sufficiently hot to fuse with the thermoplastic mounting portion of the insert.
