Abstract
PURPOSE: To produce efficiently a synthetic resin molded article having a metal- plated pattern in the central part on the outer surface thereof, by plating the molded article produced from an electrically conductive resin, through electrical contacts provided on a specified part.
CONSTITUTION: A synthetic resin which was made electrically conductive by incorporating carbon therewith, is injection molded. A concave part 1b is provided on the surface of the resulting molded article so that a desired pattern part 1a is formed in the central part and an outer circumference rib 1e is formed on the circumferencial part. On the reverse side, a base 1f2 is formed on an opposite side to the pattern part 1a and bosses 1f are formed on an opposite side to the concave part 1b. The concave part 1b is coated by using a mask, etc. to form a coating film 2. Then the molded article is striked by using said bosses 1f2, 1f as electrical contacts, and then is electroplated with copper or nickel to form a metal-plated layer 3 having a uniform thickness on the pattern 1a, the rib 1c and the side wall part 1d.
