Tungsten Carbide Tube Drawing Die

Tungsten carbide tube drawing die uses tungsten carbide as mandrel and outer inlaid steel, which plays an important in drawing copper and steel tube. It has higher requirement to surface roughness, generally polished to mirror and no cracks and other defects. Common grades are YG6, YG6X, YRL 10, YG8, YG15, etc. It uses tungsten carbide as mandrel, which has high hardness, toughness, low friction coefficient, excellent wear and corrosion resistance and mainly used for drawing copper, steel and other metal tubes. There are some specifications of tube drawing die as follow:

In addition, it should be notice that when we are using tungsten carbide tube drawing die:
1. Equipment select: According to the drawing material and equipment, allocate the compression ratio of each tube to determine the angle of the workspace;
2. Pre-treatment: such as cleaning, descaling, annealing, phosphate, etc., to ensure cleanliness of materials;
3. Drawing agents: choose proper drawing agents (lubricant, oil) to cool the tube drawing die;
4. Aging and replacing: Avoid the abuse of the tube drawing die and timely replace the mold.
