Nano-coated copper wire mold:
Size range: 1.0~80mm.
The nano-coating drawing die is based on cemented carbide (YG-6) as the substrate, and uses chemical vapor deposition (CVD) to carry out nano-level diamond composite coating on the inner hole surface of the die, and the coating is precisely After grinding and polishing, a new mold is obtained. The nano-coating on the surface of the inner hole has the characteristics of strong adhesion and good wear resistance, and has the advantages of extremely high smoothness, low friction coefficient and easy grinding and polishing. In the process of wire drawing, the performance far exceeds the service life of traditional molds by 10 to 100 times. Excellent surface finish and low coefficient of friction keep the pore size unchanged for long-term drawing. Saving consumables and labor, high dimensional accuracy reduces the number of downtime inspections and mold changes, and improving production efficiency is an essential mold for copper wire drawing.
