Abstract

Mold pins for use in a mold matrix, as used in the production of electroforms, are provided with means to alter the longitudinal axis of the pins relative to that of adjacent pins so that the longitudinal axis of the pins are tapered with respect to one another towards the operative ends of the pins. In one embodiment of the invention a dowel is inserted into a sidewall of the pin and extends normal thereto to space the pin from an adjacent one. In another embodiment, a spacing member of a desired thickness is applied to the shank of the pin at a location remote from the operative end thereof.
