TC Drawing Dies

Tungsten Carbide wire dies have been widely used in wire drawing industry. Eastleads has been offering TC products to wire drawing and extrusion industry for 30 years. Nowadays, carbide dies are still widely used in many cost effective situations. At the same time, TC dies have the widest diameter range, which is the perfect consideration in rods application.
