SURFACE TREATMENT METHOD OF A MOLD AND A MOLDING TREATED BY THE SAME, CAPABLE OF IMPROVING THE DEMOLDABILITY BY FORMING A PROTRUSION

摘要

PURPOSE: A surface treatment method of a mold and a molding treated by the same are provided to prevent scratches on a surface of a workpiece and an abrasion of a mold by avoiding concentration of load on a part of the mold surface.;CONSTITUTION: A surface treatment method of a mold is as follows. A removal of a hardened layer or adjusting a surface roughness on a surface of a mold is operated by a first blasting. A micro unevenness is formed on the surface of the mold by a second blasting. A peak of a protrusion is flattened by a third blasting. Sprayed abrasives in the third blasting are slid along the surface of the mold.;COPYRIGHT KIPO 2012
