Abstract

943,167. Moulding processes. PRECISION METALSMITHS Inc. Jan. 12, 1962, No. 1261/62. Heading B3F. Soluble synthetic resin patterns 13 are secured to a wax or synthetic resin support 12, invested with refractory material 15 and removed from the shell by removing the support 12 to expose a portion 16 of the pattern assembly and thereafter allowing a solvent for the pattern material to contact at least the exposed portion of the pattern assembly for a time sufficient to dissolve or soften the pattern material to such an extent that expansion of the material when heated will not damage the shell, and finally heating the shell to volatilize any remaining pattern material. The pattern assembly is dip-coated and some coats may be applied after removal of the pattern. The pattern support is of wax or synthetic resin formed on a metal former 11 which is removed to allow the wax or resin to be melted or dissolved. The solvent may be for example methyl ethyl ketone or trichloroethylene.
