Method of making moulds of a high melting point metal by spraying said metal onto a filled silicone-rubber former

摘要

The present invention relates to a metal mold manufacturing process by spraying molten metal on a shaped elastomeric silicone, characterized in that the silicone elastomer contains from 20 to 90% by weight of fine particles of at least one refractory filler and in that said metal is a high melting point metal (10).; Use as a mold for plastic molding objects or as punch or matrix of a press shell high melting point metal obtained by the method of the invention.
