Abstract

A molding process includes forming a primary molded product having interlocking projections and holes in a primary mold. The product is transferred into a secondary mold having interlocking grooves and pins, and secured therein by the engagement of the projections and holes of the product with the grooves and pins, respectively, of the secondary mold. A secondary molded product containing the primary molded product as an insert is formed without having any undesirable displacement of the insert caused by the injection of a molding material at a high pressure. An appropriate molding apparatus is also disclosed.
