METHOD OF PRODUCING SYNTHETIC RESIN STAMP

摘要

A method of producing a synthetic resin stamp includes the steps of mixing 35 to 45 weight % of a polyethylene resin, 11 to 22 weight % of a thermoplastic elastomer, 35 to 45 weight % of a filling material, 2 to 7 weight % of a cross-linking agent, and 2 to 7 weight % of a foaming agent to obtain a molding material; placing the molding material in a molding die; performing a direct pressure molding at 160° C. to 190° C. for 3 to 10 minutes for performing a cross-linking reaction and a foaming reaction to obtain a foamed molded member formed of foam cells; slicing the foamed molded member to obtain a sliced member; and performing a laser engraving process on a surface of the sliced member to obtain the synthetic resin stamp.
