Abstract

PURPOSE: A decorative copper plate that is heated under specific conditions is immediately coated with a transparent synthetic resin melt extruded, thus producing a decorative copper plate coated with pinhole-free and thick film of synthetic resin.
CONSTITUTION: A decorative copper plate 1, such as a colored copper plate or copper-plated metal sheet, is continuously introduced into a furnace 2 kept to 120W 270°C and heated so as to satisfying equation Y 19W0.07X (Y is time heated in min; X is temperature of the furnace in °C). Then, the plate is immediately put in mold 5 connected with extruder 4 and a transparent synthetic resin 3 is extruded into mold 5 to coat the copper plate.
