Abstract
A method for molding comprises: passing molding material through a nozzle, a nozzle inlet, and a sprue; diverting the flow of the molding material into a mold cavity with a spreader; and introducing the molding material to the mold cavity. The spreader can be part of the mold or of the nozzle. In one embodiment, the mold can comprise: a mold cavity; a sprue in fluid communication with the mold cavity, the sprue having a nozzle inlet and being adapted to receive fluid from an injection nozzle; and a spreader protruding from an interior surface of the mold cavity opposite the sprue. Alternatively, the nozzle can comprise: a bore disposed within the nozzle; an orifice disposed at an exit end of the nozzle, wherein the orifice is in fluid communication with the bore; and a spreader movably disposed through at least a portion of the bore, wherein at least a portion of the spreader is adapted to extend from the bore to a point external to the nozzle such that when fluid exits the orifice in a fluid flow direction, the spreader will alter at least a portion of the fluid flow direction.
