ABSTRACT:
A simultaneous injection molding and patterning method, including the steps of providing a first mold and a mutually opposed second mold; interposing a decorative pattern sheet between the molds; moving a heating body from a non-heating position to a heating position so as to heat and soften a portion of the decorative pattern sheet positioned between the opposing molds. The heating position is arranged such that a heating surface of the heating body confronts the decorative pattern sheet while the sheet is positioned between the opposed molds, and the non-heating position is arranged such that the heating surface of the heating body is not parallel to the heating surface of the heating body when in the heating position. The first mold is then evacuated to bring the heated and softened decorative pattern sheet into contact with a cavity of the first mold, the molds are closed, and then molten resin is injected into the mold to form a patterned product including the decorative pattern sheet.
