FOUNDRY MOULDING

Introduced: September 1968

Classification Context

Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: CASTING; POWDER METALLURGY
Subclass:: FOUNDRY MOULDING

Description

B22C covers the equipment, processes, and techniques used to produce foundry moulds for metal casting. This includes mould making methods (such as sand moulding, shell moulding, and investment casting), mould materials preparation, pattern equipment, and apparatus for assembling and finishing moulds. The classification encompasses both manual and mechanized moulding operations, as well as related processes like mould drying, venting, and core making. Adjacent classes address metal casting itself (B22D) and specific casting techniques, while B22C focuses specifically on the mould fabrication stage that precedes the actual metal pouring.
