Method for structuring surface of deep-drawn three dimensional decoration molded part, involves deforming decoration molded part directly and indirectly in high-pressure molding process in molding tool by fluid pressurizing agent

摘要

The method involves deforming the decoration molded part directly and indirectly in high-pressure molding process in a molding tool by a fluid pressurizing agent. The decoration molded part is heated for hardening the coating or is radiated with ultraviolet-radiation. The outer contours and breakthroughs are cut or punched out along given contours before the back injection molding. The prefabricated, non-back injection molded decoration molded part is placed in the same tempered high-pressure deformation tool or in a patterned tempered tool. A pre-heated impression film is placed in the open tool, whose lower side has a desired surface structure. The pre-heated film is impressed on the surface of the decoration molding part by high pressurization with fluid pressurizing agent after closure of the tool.
