METHOD FOR PRODUCING MOLD AND MOLD

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a mold which can produce the mold in a short time and improve the physical strength of the mold and the mold with its physical strength improved. SOLUTION: The method for producing the mold includes the first process in which a coating film material is made to collide against the surface of a master model 1 having an appearance equivalent to a molding with a carrier gas to form a coating film layer 2 and the second process in which the coating film layer 2 formed on the surface of the master model 1 is released from the master model 1 to obtain the mold. No electrocasting layer 3 is formed on the molding surface of the mold, and the mold is composed of only one metal layer. COPYRIGHT: (C)2009,JPO&INPIT
