Carbide drawing dies
Tungsten carbide drawing dies are used in wire drawing industries for drawing of different materials like Mild Steel (M. S), High Carbon (H. C), Stainless Steel (S. S), Brass, Aluminum, etc. All major wire producers use tungsten carbide drawing dies. We can supply different dies, such as drawing die, punching die, extrusion die, cold heading die, which are fully finished or rough cored - cased or uncased, to meet client's exact requirements.
We make drawing pellets from W104 to W114, or Sxx series, or customized as per cutomer's drawing. Grade usually in K20 and K30.
tungsten carbide drawing nibs for the full range of wire drawing application: high-carbon wire, steel cord for rubber reinforcement, bead wire, welding wire, stainless wire and spring wire.
1). 100% virgin powder.
2). Can drawing copper, iron, steel, and other metals.
3). Can offer both blank and finishing with casting.
4). Also offer unstandard size according to customer's requirment.
1. Structure of dies:
The hole of the wire drawing dies is made up of four parts:
* Lubricating area of the entry: There's an arc to make the wires enter the workaround conveniently.
* Workaround: The metals come about plastic deformation while drawing, the cross section of the metals is compressed and reduced.
* Diameter fixed district: To guarantee the size and form accurate and even, lengthen the service life of the die.
* Wire outlet area: Wire outlet terminal can prevent scuffing and break-up when the machine is stopped.
2. Usage Time:
The whole set of dies can guarantee drawing 30, 000 tons of copper wires. It can reduce the copper powder in the course of drawing. The surface of finished wires is smooth without and defect. After the dies drawing copper wires of 30, 000 tons, it will not be damaged, but needs to safeguard, maintain, and Polish.
