Abstract
An injection molding machine of the present invention includes a first mold half having one of at least one mold cavity and at least one mold core and a rotatable turret block rotatable on an axis for rotating a plurality of movable mold halves thereof into alignment with the first mold half. Each of the movable mold halves include one of at least one mold cavity and at least one mold core matable with the first mold half for forming a mold for molding a molded article. The rotatable turret block is further for clamping the movable mold halves and the first mold half together. The machine further includes a mechanism for moving the rotatable turret block relative the first mold half, a first injector for injecting melt into the at least one mold cavity, to form an injected article and a second injector for injecting melt into the at least one mold cavity over the injected article to form an injected article having at least two layers.
