Both casting and powder metallurgy are near-net-shape processes that use molds to shape raw materials into components.

Casting melts the metal to create the part, while powder metallurgy shapes the part at temperatures below the metal’s melting point.

Powder metallurgy uses metal powder as the raw material, while stamping uses flat metal sheets.

Powder metallurgy is suitable for high-volume manufacturing of complex-shaped parts, whereas stamping is faster for producing simple shapes in large quantities.

Powder metallurgy produces components through die compaction and sintering, while machining removes material from a solid block to achieve the desired shape.

Powder metallurgy is ideal for large quantities and complex, intricate features, whereas machining is better suited for precise dimensions and smaller batches.
