Abstract
A method and apparatus for cold runner transfer molding. Insulating and/or cooling means are provided so that the mold runnerblock is kept sufficiently cool to prevent curing of the plastic molding compound therein. By the addition of a plunger near the gate of the mold, a quasi-continuous molding operation may be effected. Local preheating of the molding material at the gate locale may be used to liquefy a feedstock which has travelled through the cold-runners in powdered form.
