ABSTRACT:
High melting point metallic, e.g., steel mold members are facilely and inexpensively produced by depositing, e.g., flame-spraying, droplets of a melt of a metal having a high melting point onto the front face surface of an elastomeric silicone mold pattern, said elastomeric silicone containing from 20 to 90% by weight of finely divided particulates of at least one refractory filler, and thereafter permitting said melt to solidify.
