Insert manufacturing method for realizing rigid plastic piece of pattern and/or information support device, involves separating metal stamper obtained by galvanizing modified support delivering insert

摘要

The method involves fixing a lenticular portion (41) of a plastic film (42) on a support to deliver a modified support. A film of a metal is deposited on the modified support to superficially harden the plastic film. The modified support is galvanized in an electrolytic bath to realize the successive deposit of another metal. A metal stamper (43) obtained by galvanizing the modified support delivering an insert is separated, where the insert is positioned within a die cavity of a mold in which the thermoplastic polymer based material is injected. Independent claims are also included for the following: (1) a method for manufacturing a rigid plastic piece (2) a rigid plastic piece comprising a portion with a set of concentric annular sections (3) a pattern and/or information support device comprising a plastic piece.
