ABSTRACT:
A wall of a four-piece mold is made by machining cooling channels into one side of a steel backup member. The cooling channels are filled with wax which is then covered with conductive paint or tape. A layer of copper is now electroplated onto the side of the backup member with the cooling channels, and nickel and chromium are plated over the copper in succession. Upon completion of plating, the wax is removed from the cooling channels by melting the wax. Alternatively to machining the cooling channels into the backup member, strips of plastic are adhesively secured to the backup member prior to plating. The plastic strips, which have widths and heights equal to the desired widths and depths of the cooling channels, are placed on the backup member at the intended locations of the cooling channels. Copper is plated onto the backup member to the height of the strips which are then removed to form the cooling channels. The cooling channels are filled with wax and the process of making the mold wall is then completed as before.
