Abstract
Apparatus and a process for manufacturing plastic shells having decorative features thereon includes a method for casting thermoplastic material against a heated mold by use of a combination mask and container unit (hereinafter referred to as the combination unit) that is joined to a known heated mold to deposit a first semi-cured deposit on the mold from supplies of material in the combination mask and container; the mask is configured to have a plurality of wire reinforced foot portions with sealing edges configured to be aligned with the sharp edges of recesses in the mold surface defining the decorative feature; when the combination unit is inverted it casts material only on the recesses to form a semi-fused deposit of a first color. The combination unit is separated from the mold which is then processed to a higher fusion temperature and a base layer of contrasting thermoplastic material is cast thereon to be bonded to the recess material prior to cooling and stripping the mold.
