METHOD FOR PRODUCING PLATED MOLDED PRODUCT

摘要

A METHOD FOR PRODUCING A PLATED MOLDED PRODUCT IS PROVIDED, IN WHICH A SURFACE OF A MOLDED PRODUCT HAVING A THIN PORTION OBTAINED BY COINJECTION MOLDING OF RESIN IS SUBJECTED TO PLATING. A SURFACE OF A MOLDED PRODUCT HAVING A THIN PORTION OBTAINED BY HIGH-SPEED INJECTION MOLDING OF RESIN IS PLATED BY STEPS: ( A ) FORMING A METAL PLATING LAYER ON A SURFACE OF THE MOLDED PRODUCT BY ELECTROLESS PLATING; ( B ) FORMING A COPPER PLATING LAYER ON A SURFACE OF THE ELECTROLESS PLATING LAYER BY ELECTROPLATING; ( C ) FORMING A NICKEL LAYER ON A SURFACE OF THE COPPER PLATING LAYER BY ELECTROPLATING; AND ( D ) FORMING A CHROMIUM OR CHROMIUM ALLOY LAYER ON A SURFACE OF THE NICKEL LAYER BY ELECTROPLATING . EVEN FOR A MOLDED PRODUCT HAVING A THIN PORTION OBTAINED BY HIGH-SPEED INJECTION MOLDING, A PLATING WHICH RESISTS REMOVAL CAN BE OBTAINED. FURTHER, EVEN WHEN A PLATING IS FORMED ON A SATIN-FINISHED SURFACE, THE PLATING CAN REPRODUCE THE SATIN-FINISHED SURFACE.
