发明名称 USING A CONVENTIONAL FLAT DRAWING OR A FLAT MOSAIC STYLE PASTE-UP OF A DESIGN TO PRODUCE OPEN FACED CASTING MOLDS OR VACCUUM FORMING MOLDS
摘要 The invention relates to a method of using a flat two dimension drawing or a flat two dimensional mosaic style design and etching the drawing or design into the surface of a photoengraving plate, to a predetermined depth, in a positive or negative aspect; using the photoengraved plate and placing a centrally opened frame onto the surface of the photoengraved plate and casting into the area of the frame a pourable, non-thixotropic, silicone based compound, to produce a flexible membrane; using the membrane in conjunction with cast epoxy, polyester or acrylic based compounds to produce open faced casting molds or vacuum forming molds that reproduce the form and details of the drawing or design in a three dimensional form, in a positive or negative aspect, to be used in the production of massive castings or thin vacuum formed replicas of the drawing or design.
