Cold drawing is the process of deforming a flat metal plate into the shape of a side wall. Drawing usually refers to deep drawing, drawing to a depth of more than half its diameter. SDWST offers a variety of cold work steel options to achieve low-cost, high-efficiency production goals and optimal work efficiency.

The choice of mold material is crucial. Due to the sliding contact between the alternating mechanical load and the processed material and the mold surface, the mold surface is gradually damaged. Sooner or later, mold damage will lead to quality problems in the molded parts (outside of dimensional tolerances or poor surface quality). As a result, the only option is to replace the mold (complete failure) and regrind or polish it. Our industry experience shows that wear, chipping, plastic deformation, cracking and adhesive napping are the most common failure modes.

Maintenance means interruption of production and loss of productivity. It is crucial to choose mold steel that can effectively resist various failure mechanisms, so as to improve production efficiency and economic benefits. Selection of an appropriate mold steel should take into account the mold's ability to resist relevant failure mechanisms. In view of this, we emphasize the importance of evaluating the overall mold economics when selecting the appropriate mold steel.
