Abstract: PROBLEM TO BE SOLVED: To manufacture a composite article subjected to texture finish resistant to damage by casting work at a low cost using a polymer casting mold having a casting surface. SOLUTION: In a casting process using a texture interface layer 20 for separating the surface of the casting mold 10 from the surface of the composite article 12 manufactured using the casting mold 10, a solution is deposited on the surface 18 of the casting mold 10 in order to form the interface layer 20. The surface of the interface layer provided on the opposite side of the casting mold is formed into a textured surface. Next, the texture of the interface layer 20 is transferred to the surface of the composite article 12 manufactured by the casting mold 10. After the casting mold 10 is detached, the interface layer 20 is bonded to the composite article 12 as a protective coating. Since the textured surface provided on the under side of the article 12 is exposed, the interface layer 20 can be easily removed from the article 12.

Abstract: A molding process that uses a textured interfacial layer to isolate the surface of a mold (10) from the surface of a composite article produced with the mold (10). A solution (20) is deposited on the mold surface (18) to form the interfacial layer, whose surface (22) opposite the mold (10) is textured. The texture of the interfacial layer is then transferred to the surface of the composite article produced with the mold (10). After demolding, the interfacial layer adheres to the article as a protective coating, but can be readily removed from the article to expose an underlying textured surface of the article.
