摘要：A method for manufacturing decorative features in situ in a base layer castplastic material includes the steps of providing a mold tool having a surface thereonwhich is recessed in the form of a desired decorative feature and includes a sharp breakline between the recess and the surrounding mold surface; depositing a covering ofthermoplastic material in the recess surface and heating the tool to melt the
thermoplastic material on the recess surface to form segments of plastic correspondingto the desired decorative feature; thereafter cooling the covering and stripping it fromthe mold by separating it at the sharp break line interface between the depositedmaterial on the recessed surface and a thin film membrane formed on the remainder ofthe mold surface so as to retain segments of material deposited in the recesses of themold tool; reheating the mold tool recess to partially remelt the retained segments andthereafter depositing a base layer of thermoplastic material across the surface of themold and reheating the mold to bond the retained segments to the base layer andcooling and stripping the mold to form a finished plastic shell having a decorative featureformed in situ therein.
