Abstract

The invention relates to a device for the production of bonded plastic/metal parts in the cavity of a modified injection-molding tool by a combination of metal-joining techniques and conventional injection-molding processes.

Claims

1. A device comprising one or more pressing dies 2 having a distal clinching portion, a cavity formed in a corresponding lower die of an injection molding tool 1, said injection molding tool having means accommodating individual metal sheets 4,5 having juxtaposed holes therein, said injection molding tool having an inlet for injected thermoplastic material, said metal sheets being clinched at the juxtaposed holes by the coaction of said one or more pressing dies and said lower die, said one or more pressing dies being retractable from the cavity of the injection molding tool in order to inject thermoplastic material into a mold formed at least by said one or more pressing dies and said lower die.
