12. Jan. 2021 · Cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature. Both the production and manipulation of metals has long been associated with high temperatures. Since man moved beyond the use of naturally occurring materials like wood and stone, and ...
冷間加工（れいかんかこう、英語：cold forming）とは塑性変形を利用した加工方法。常温もしくは材料の再結晶温度未満で行なう加工である。主に金属材料で用いられるが、鋼の場合、通常は摂氏350-500度未満で行われる。
29. Jan. 2023 · Cold-working is one of the important methods of metal forming that help manufacturing industries produce a different variety of products. There are different methods of cold working like cold rolling, cold extrusion, cold drawing, sheering, and bending but the most commonly used method is sheering and cold drawing.
Cold forming has the effect of increasing the yield strength of steel, the increase being the consequence of cold working well into the strain-hardening range. This increase is in the zones where the material is deformed by bending or working. The yield stress can be assumed to have been increased by 15% or more for design purposes. The yield stress value of cold-formed steel is usually ...

Defremm S.p.a. is a specialist in cold forming wire in steel and aluminium, copper and stainless steel alloys, IATF 16949:2016 certified and a leader in digital transformation. Defremm manufactures special parts to customer drawings for a number of applications including automotive, and standard fasteners such as ...
Cold forming causes directional grain orientation, which can be controlled to produce desired directional strength properties. Also, work manufactured by cold forming can be created with more accurate geometric tolerances and a better surface finish. Since low temperature metal forming processes do not require the heating of the material, a large amount of energy can be saved and faster ...
