DEFINITION

Classification: 164/6

(under subclass 1) Process which includes the step of producing by shaping (1) a mold, pattern or core device either as a, per se, operation by a method within the definition of this class or (2) in combination with a step of employing said mold or core device in the production of a cast product by a process classifiable in this class in which latter instance the mold or core device may be formed by methods provided elsewhere.

(1) Note. Also included herein is the shaping of a mold to be used in nonmetal molding of fluent or flowable materials if such shaping is performed on fluent metallic material.
