METHOD FOR PRODUCING COVER MEMBER FOR ELECTROMAGNETIC WAVE SHIELD AND COVER MEMBER FOR ELECTROMAGNETIC WAVE SHIELD

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a cover member for electromagnetic wave shield which can execute injection molding of a cover part having a thickness of 0.2 mm or less by preventing the generation of defective appearance, and to provide a cover member for the electromagnetic wave shield which has the cover part thickness of 0.2 mm or less and can be produced at a high yield. SOLUTION: In the production method for producing the cover member 1 for electromagnetic wave shield to be produced by forming a metal layer 6 on the surface of the cover part 3 of the injection molded product 2 which is equipped with an electronic part housing section 5 and the cover part 3 for covering the electronic part housing section 5, the injection molding machine is set to less than 294 MPa (3000 kgf/cm2) for the injection pressure and set to 500 mm/second or more for the injection speed to injection mold the cover part 3 having a thickness of 0.2 mm or less.
