ABSTRACT:
A method for forming a product having a substrate and an overmold material secured thereto, with the substrate having a shape substantially as set forth in a predetermined design, and further with the product being formed in a molding machine that erodes portions of the substrate during a step of injecting the overmold material into a molding cavity of the molding machine. The method includes the step of providing the substantially design-shaped substrate having a compensation member secured thereto. The method further includes the step of placing the substantially design-shaped substrate having the compensation member secured thereto into the molding cavity so that the compensation member is positioned in a path of flow of the overmold material during the step of injecting the overmold material into the molding cavity. Moreover, the method includes the step of injecting the overmold material into the molding cavity so that the flow of the overmold material contacts and erodes the compensation member so as to form the product having the substantially design-shaped substrate and the overmold material secured thereto.
