Kylmämuotoilun

Kylmämuotoilu refers to a metalworking process where metal is shaped at or near room temperature without significant heating. This contrasts with hot forming, where metal is heated to a malleable state. Kylmämuotoilu relies on the application of external forces to deform the metal's shape, often involving processes like rolling, drawing, extrusion, stamping, and forging.

The primary advantage of kylmämuotoilu is that it generally results in a stronger and harder material due to strain hardening. This process can also achieve higher dimensional accuracy and better surface finish compared to hot forming. However, it requires more force and can introduce residual stresses into the material. The ductility of the metal is reduced during kylmämuotoilu, making it more brittle. Common applications include the production of wires, sheets, tubes, screws, and various automotive and aerospace components where strength and precision are critical. The specific method chosen depends on the desired shape, the type of metal, and the required tolerances.
