ABSTRACT:
An apparatus for practicing a method for forming a 360 degree integral skin handle in a thermoplastic part for use in automotive trim products. The apparatus includes a mold with a recess therein and a plug being supported on the mold for movement into a position for closing the tube surface and into a demolding position for releasing the molded part. A heater device directs heat from a first source through the mold and from a second source through the plug to form a completely closed, curved, heated tube surface on which thermoplastic material is cast against the curved, heated tube surface to fuse and cure a layer of material thereon in the form of a tube skin segment which is releasable from the mold when the plug is removed.
