Abstract

A mold for stepwise molding, using two different plastics, signage composed of a plurality of symbols surrounded by a continuous matrix including a first mold member having a first cavity defining surface including at least one first gate for admitting a first plastic, and a second mold member movable with respect to the first mold member having a second cavity defining surface confronting the first cavity defining surface. The cavity defining surfaces are spaced from each other by a predetermined distance to define a first cavity receiving the first plastic. The second mold includes lateral surfaces defining at least some of the plurality of symbols. At least one second gate is provided in the first mold member, each second gate admitting a second plastic only when a second cavity is defined so that at least a portion of the lateral surfaces defining at least some of said plurality of symbols are retained in position as the second plastic is injected.
