WOCO's tungsten carbide cold heading dies are made from high quality raw powder, it obtains low impurity content and it is no crack. Processed by importing press machine and sintered by over pressure sintering furnace, it has regular type and little tolerance. They are widely used in ball & fastener industry.
WOCO cold heading die feature
We promise our cold heading dies are made of high purity tungsten powder(99.95％ raw materials) and crack will not happen. The strenght of the die core is more than 2200 n/mm3; Long service life:we take the unique formula and add wear-resisting material element into my tungsten carbide dies; Processing costs are lower; Wear and impact resistance; Stock for the fast moving styles; Precisely engineered ; the die core will not take off the moulds; Quick delivery: various models mold is complete, the production cycle fast, even if no inventory spot, 4 days production time of delivery.
