CASTING; POWDER METALLURGY

Description

Class B22 covers manufacturing processes for creating metal and alloy components through casting and powder metallurgy techniques. Casting encompasses melting metals, forming them in molds, and solidifying them into desired shapes, including sand casting, die casting, investment casting, and continuous casting methods. Powder metallurgy involves compacting metal powders and sintering them to produce finished or semi-finished parts, enabling manufacture of complex geometries and composite materials with controlled properties. This class includes foundry equipment, mold preparation, heat treatment during casting, powder production, consolidation processes, and quality control methods specific to these manufacturing routes.
