A substrate is permanently bonded to a thermoplastic member by applying a sufficient degree of heat and pressure. Thermoplastic is notoriously non-receptive to even the most aggressive adhesives. As such, it has been extremely difficult to attach non-plastic components to thermoplastic products. To avoid this problem, the thermoplastic product is heated, on one side, to a temperature just below its melting point. A substrate, made of a material such as polyethylene, is placed against the non-heated side of the thermoplastic. As heat passes through the thermoplastic, it heats and eventually melts a portion of the substrate. Ideally pressure is applied to force the melted material against the substrate. The materials are then allowed to cool and harden, thus forming a permanent bond between them. Additional materials may be coupled to the substrate, as desired.
