III.Advantages of old craftsman wire drawing dies:
- Good wear resistance: Tungsten carbide possesses high wear resistance, which could guarantee long-term work of drawing within any drawn amount and ensure the size and precision of products.
- Excellent polishing: Carbide enjoys good polishing, and the die hole can be processed to the degree of mirror, thus ensuring high-quality of metal drawn surface.
- Small adhesion: In the drawing process, the drawing die keeps little adhesion with metal processed, thereby enhancing the durability of drawing die and making processed material acquire high-quality gloss finish for surface.
- Small friction coefficient: In the drawing process, smaller frictional resistance means less the power loss, thus enhancing overall efficiency.
- High coefficient of thermal conductivity: In the drawing process, the generated heat can be conducted away very well.
- Good corrosion resistance: This property is superior in the wet lubricated stretch, especially in the acidic lubricated stretch.
IV.Application of wire drawing dies:
- Steel wire and stainless steel wire
- Copper wire
- Alu wire and tungsten wire
- Various kinds of ferrous and non-ferrous metal wire
