ABSTRACT:
A process for metal plating shaped articles, such as cast or molded articles of synthetic resins, includes the steps of (a) diffusing or scattering numerous fine metal particles (or pieces) over the surface and outermost layer of the articles, (b) etching exposed surfaces of the metal particles, (c) performing thereafter metal plating, (d) and thereby solidly combining or joining the plating layer and the articles through the medium of the fine metal particles, whereby the resulting plated articles are extremely eminent in abrasion and shock resistance which is essentially useful for casting and molding patterns or core boxes.
