ABSTRACT:
A method is provided for producing a molded composite form comprising a substrate bonded to a thermoplastic element whereby the thermoplastic element, either separate from or together with the substrate, is heated to a first temperature sufficient to soften prior to placement in a mold with the substrate. The thermoplastic element and substrate are then comolded in a cool mold whereby the composite is cooled and shaped into a predetermined configuration in one operation.
