PROCESS FOR MANUFACTURING A MOLDED PLASTIC PIECE WITH EXTERIOR GRAIN SURFACE OF HIGHER QUALITY.

摘要

The present invention relates to a method of manufacturing a molded plastic part with a grained external surface, characterized in that it successively comprises the following steps: injection of a first thermoplastic polymer into a molding cavity delimited by a punch and a first die so as to constitute a rigid support (100); removing said first matrix and replacing the latter by a second matrix having a negative grained decorative pattern by direct laser incision and delimiting with said punch and said rigid support an overmolding cavity (200); injecting a second polymer into said overmolding cavity so as to constitute a skin of coating overmolded against said support and having a grained external surface reproducing said pattern (300); and - removing the second die and ejecting said molded piece (400).
