Cold forming and cold heading shape fasteners and small metal parts at room temperature using high-pressure dies, work-hardening the material rather than melting or heating it. It’s the dominant process for high-volume bolts, rivets, and similar hardware.
This is a tooling-intensive, very-high-volume process — it only pays off once part counts run into the hundreds of thousands, where the die cost amortizes to near nothing per part.
Related terms: cold heading, multi-station forming, work hardening, die design for cold forming, wire and rod stock preparation, grain flow orientation, fastener thread rolling, progressive die tooling, material yield optimization
