Process for the manufacture of a trim piece by means of molding followed by thermo-forming

摘要

The purpose of this invention is a manufacturing process (100) of a trim (1) for an automobile using a forming mold (4). The process comprises the steps manufacturing (101) a substrate (2) comprising vents for the passage of air, depositing (103) of said substrate (2) against a first part of the forming mold (4), placing (104) a sheet (6) in the open forming mold (4) between the substrate (2) and a second part of the mold, and allowing air to aspirate (106) from the forming mold (4), in such a manner as to plate the sheet (6), on the one hand, against the forming mold (4) at the second part of the mold, and, on the other hand, against the substrate (2). This process further comprises an additional stage consisting in placing (107) a flat multilayer insert (8) against the surface of the second part of the mold, in such a manner that the sheet (6) comes to mold with the form of the insert once the forming mold (4) is closed.
