PRODUCTION OF LAMINATE TYPE RESIN MOLDING

摘要

PURPOSE:To prevent the generation of burr on the joint surface between first and second resin moldings by making a protruded wall provided on the first resin molding abut against the inner wall of a concave of a mold when a resin fills for the second resin molding. CONSTITUTION:The second resin molding 22 as a unwinding control button is different in the color from the first resin molding 21. After the formation of the resin molding 21, it 21 is inserted to join a die 34 having concave 33 for forming the outer surface of the resin molding 22 with a die 27. The concave 33 is formed to be a tapered surface with the inner wall thereof expanding toward the opening. With the joint thereof, a protruded wall 26 formed on the resin molding 21 is pressed to the center of the resin molding 21 against the inner wall of the concave 33 of the die 34. Therefore, a space generated between the outer wall of the resin molding 21 and the inner wall of the concave 33 of the die 34 is closed thereby providing a control button of a high quality free of burrs, flaws and the like with a clear interface between both of the resin moldings.
