<p>PURPOSE:To obtain a resin-made mold having a high adhesive power between a thermosetting resin layer and a metallic back-up material and a superior durability by a method wherein a metallic material is used as the back-up material, a stress reduction resin layer is formed on the surface thereof, and thereon a thermosetting resin material is bonded. CONSTITUTION:In the construction of a resin-made mold, a metallic material is used as a back-up material, a stress reduction resin layer is formed on the surface thereof, and thereon a thermosetting resin material is bonded. The stress reduction material used in this invention is disposed between the thermosetting resin layer forming a molding surface and the metallic back-up material for the purpose of securely bonding the both to each other. If the thermosetting resin layer forming the molding surface is directly bonded to the metallic back-up material, a residual stress caused by a difference in linear expansion coefficient between the both occurs in the interface, thus resulting in a trouble, such as an occurrence of peeling. If the stress reduction material capable of effectively reducing the residual stress is provided on the interface, the adhesion can be improved to a great extent.</p> |
