Abstract: A multi-material mold and method of making multi-material parts is disclosed. The mold comprises a core half having a first station and a second station, a slide, and a cavity half movable with respect to the core half between a first closed position wherein the at least one slide cooperates with the first station of the core half and the cavity half to define a first mold cavity adapted to form a portion of a part, and a second closed position wherein the portion of the part cooperates with the second station of the core half and the cavity half to define a second mold cavity. The slide is slidable between an extended position adapted to hold the portion of the part formed in the first mold cavity to the cavity half, and a retracted position adapted to permit the part to exit the mold. Optical surfaces can be placed on the core half.
