Abstract

The metal core is fed through a first die, and a layer of a compact thermoplastic is extruded around the metal. This extrusion is fed into a second die which forms the first thermoplastic in shape and extrudes a second thermoplastic material, which has an expanded consistency, onto the core. This produces a seal assembly without additional assembly operations, and allows a large variety of cross sectional forms to be produced with a strong bonding between the sections.
