Method of making plastic articles with a substantially enveloped core

Claim 1

A method of producing an article having a cast plastic body which substantially and equally envelops a core comprising the steps of: a. providing a mold having a base and wall b. providing a core having spacing elements on the underside and an undercut about its periphery edge c. positioning said core upon said base and spaced from said mold wall with the undercut edge facing said base d. introducing into said mold in a quantity sufficient to cover the upper core face and periphery edge, at least one layer of core masking material, said material being polymerizable and gellable liquid mixture having at least one amount of at least one kind of orientable media added thereto e. dispersing and orienting said orientable media by agitating said liquid mixture at least partially downward from the upper liquid surface to achieve a desired pattern f. suspending said dispersing and orienting operation when the increase in viscosity of said liquid indicates that the gel stage is reached, permiTting the pattern to remain fixed in the resin g. permitting said core masking material to harden, and h. removing the finished article from the mold.
