Abstract
The plastic substrate portion of the part is formed by a first injection of plastic into a mold, so as to adhere to an overlying sheet of coverstock material. A portion of the coverstock is not initially adhered to the substrate. A second injection of plastic forms the undecorated portion of the part, and bonds to the substrate portion to form a unitary plastic panel. In the course of contacting the substrate portion, the plastic from the second injection folds and hides the non-adhered portion of the cover stock, thereby forming a neat, clean split line.
