Abstract:

A process for insert molding at least a portion of a flexible webbing material within at least a portion of a plastic injection molded part produces a product having a plastic injection molded part with a contour formed by a front surface and a rear surface, and a flexible webbing material having at least a portion embedded within the injection molded plastic part, while a remaining portion of the flexible webbing material extends externally with respect to the injection molded plastic part. An injection molding die is provided for insert molding the portion of the flexible webbing material within at least a portion of the plastic injection molded part. The die defines a chamber for receiving molten plastic during an injection molding step. The chamber is defined by the die having a surface for forming the contour of a front surface of at least one part to be injection molded, and another portion of the chamber having a surface for forming the contour of a rear surface of the at least one part to be injection molded. The chamber is formed by at least two separable portions of the die moveable away from one another along a parting line.
