Abstract

An injection-molded plastic part cooling tube has an extruded cylindrically shaped tube with an inside surface and an outside surface. An extruded cooling channel is disposed inside the cylindrically shaped tube, between the inside surface and the outside surface. A method for forming an injection-molded-plastic-part cooling tube includes the step of extruding a hollow aluminum tube having an inside surface, an outside surface, and at least one cooling channel in the hollow aluminum tube between the inside surface and the outside surface. Alternative cooling tubes include a tubular porous insert for vacuum forming molded articles.
