kylmätyökaluteräsperheitä

kylmätyökalu is a Finnish term that translates to "cold tool" or "cold working tool." It refers to tools and methods used in metalworking and manufacturing that shape metal at or near room temperature, without the application of significant heat. This contrasts with hot working, which involves heating the metal to a malleable state before deformation.

Common cold working processes include drawing, stamping, bending, rolling, and forging (when performed cold). These techniques rely on applying mechanical force to the metal to achieve the desired shape. The advantages of cold working include achieving tighter tolerances, better surface finish, and increased material strength due to work hardening. However, it requires more force than hot working and can introduce residual stresses.

Examples of kylmätyökalu include dies, punches, rollers, and presses used in various industries such as automotive, aerospace, and consumer goods manufacturing. The selection of specific cold working tools and processes depends on the material properties, the complexity of the desired shape, and the required production volume. The precision and efficiency offered by cold working methods make them indispensable for producing many everyday metal components.
