UNDERSTANDING METAL FORMING PROCESSES: FORGING, DIE CASTING, METAL INJECTION MOLDING (MIM), AND POWDER METALLURGY

Metal forming technologies are the backbone of modern manufacturing. Different processes are suited to different materials, geometries, and performance requirements. In this article, we compare four common metal forming methods—forging, die casting, metal injection molding (MIM), and powder metallurgy—to help engineers, buyers, and manufacturer
