  • Method of making a heat transferable mold section
    Patent number: 3969175
    Abstract: A mold section is made by covering at least the surface of a cavity of a metallic substrate with a layer of plastic barrier material. A pattern is then placed on this so-covered surface. A compressive force and heat are applied to the metallic substrate and pattern causing the material of the layer to flow and then become bonded to the surface of the cavity while duplicating the surface and shape of the pattern.
