Abstract
Abstract A process of molding a single-piece article by placing a resin body on a divider of a resin supply container containing different resins, fitting the resin supply container against a mold surface, engaging the resin body between the divider and the mold surface defining two discrete mold chambers, rotating the resin supply container and mold surface to contact the different resins against the mold surface, and heating the mold surface to simultaneously set the different resins and the resin body into a single-piece article.

Claim 1
Independent Claim
207 words
A method of making a molded product in a mold which is separable and includes a material containing mold part, a forming mold part, a partition means for dividing said material containing mold part into at least two different molding volumes, a groove means extending generally across at least one end of said partition means operative to accommodate a resin body, and a projection means on the inside of said forming mold part and cooperating with said groove means and said resin body to assist in providing said different molding volumes, comprising the steps of: placing said resin body in said groove means; placing moldable resin materials of different kinds into said molding volumes; heating said mold; placing said material containing mold part against said forming mold part to close said mold and to melt said resin body into said groove means by heat produced by said projection means to allow the entry of said projection means into said resin body; at least partially rotating said mold such that said different kinds of resin materials are placed against said forming mold part and whereby said different kinds of resin materials are bonded through said melted resin body; and separating said mold parts and removing said molded product.
