MULTI-LAYER POLYMER COMPONENT, APPARATUS AND METHOD

WIPO Patent Application WO2004094134

A3

A process and apparatus utilize a multi-layer material (101) and a section molding process in which a multi-layer length of material having a primary layer (110) and at least one additional layer (112) has a portion that is section molded through a zone heating method creating a molten zone (35) in at least the primary layer. The molten zone is aligned with a section mold to mold only that portion of the multi layer length of material. The section molded portion (20) cools forming a section molded feature. Although exemplary multi-layer components (101) are described herein, a variety of components may be produced utilizing the apparatus and method described by varying the shape of either the primary layer (110), the at least one additional layer (112), or the section molded component (20), or all.
