Abstract

PURPOSE: To facilitate the formation of dies for molding objects to be plated and their handling by forming the boundary grooves to be provided beforehand for the purpose of obtaining electrically insulated parts to a non-conductor material to be applied with chemical plating and electroplating, at specified width and depth of their opening parts.
CONSTITUTION: A knob body 1 made of rigid plastics of, for example, radios or the like is provided with a shaft connecting pipe 2 provided perpendicularly to the central part on the rear thereof. A plurality of boundary grooves 3 are provided on the rear side of the body 1 concentrically to the pipt 2. The bottom part of the grooves 3 is of a U shape in section and has roundness. The width W (mm) and depth D (mm) in the opening parts of the grooves 3 are D ≥(2W+0.1) and W is 0.1W1.2mm. The body 1 formed in this way is chemically plated as a pretreatment, but at this time, the soln. and water are hard to intrude into the grooves 3 and the bottom of the grooves form a circular non-plated belt-like part. Thence, electroplating is applied as a finish treatment on the body 1, but the connection of the chemical plating is discontinued between the body 1 and the pipe 2, and therefore no electroplating is applied on the pipe 2.
