Abstract:
A method for making a thin wall component comprise: locating a film (40) in a mold cavity of a mold, wherein the mold cavity has an initial mold thickness, wherein the film comprises a base layer (41) and a pattern layer (42); injecting a molding material (60) into the mold cavity such that the molding material contacts the pattern layer, wherein the molding material comprises a polymeric material and a filler; compressing the mold to a final mold thickness that is less than the initial mold thickness, to form a molded product, wherein the pattern layer forms a surface of the molded product; and removing the molded product from the mold. A molded product formed by the method. The method produce a thin walled component without warpage, inner stresses, poor surface quality, or washout defects.
