Abstract
Molded article and process for forming a molded article. The process includes integrally bonding foamed thermoplastic sheet or a foamed thermoplastic insert to form a capped or inserted surface onto an expanding parison during a molding process. Air between the expanding parison and the foamed thermoplastic material is evacuated into and at least partially through the foamed cellular structure. Molded articles having soft foam surface characteristics may be formed without additional pre-molding or post-molding operations. The foamed thermoplastic material may include foamed thermoplastic elastomers, foamed thermoplastic vulcanizates, or foamed thermoplastic polyolefins as extruded profiles or sheets. The molding substrate may include HDPE, polypropylene, ABS, polycarbonate or nylon.
