What is 'Cold Drawing'?
The transformation working of metal materials is usually categorized into 'hot working' and 'cold working'. Hot working is done in order to make material transformation simple at a range of high temperature while cold working is done to improve the hardness of materials at low temperature. Generally, cold drawing, a kind of cold working, is the operation that reduces the outside and inside diameters of pipes to diameters of dies through the dies hole and the plug hole respectively.
We Taejin will do our best to timely supply the products with the excellent mechanical properties by controlling the various shaping materials, the concentricity, the straightness and the surface roughness in the process of cold drawing so that we will meet the consumer's needs.
