Abstract
A method of manufacturing an in-mold forming film with a metal surface provides a metal sheet layer having a coupling surface predetermining at least one etching area, and then applies an etching measure to the etching area at the coupling surface, such that recessed structures are formed inwardly on a surface of the etching area, and then injects a plastic material to the coupling surface of the metal sheet layer by an injection pressure after the metal sheet layer is etched, such that the plastic material is forced to cover the recessed structures in the etching area, and finally cures the plastic material to carry the metal sheet layer and form a tight connection relation between the cured plastic material and the recessed structures.
