Polycrystalline Diamond wire drawing dies | ||||||||||

| α(ss)Entrance | The inlet area is polished so that the drawing fluid can circulate smoothly |
| α(sp)Approach | The lubrication area is finely polished, so that the wire can be easily excessive |
| α(rs)Reduction | The working area can reduce the drawing force, and the change-point contact is face-to-face angle drawing, which reduces friction and die wear. The deformed structure is more reasonable and stable. The upper line can be drawn smoothly when the incoming line becomes thicker or thinner. |
| d(k)Bearing | The fixed warp area can ensure the precise diameter, smoothness and out-of-roundness of the wire for a long time. |
| α(so)Back Relief | The safety angle can ensure that the wire is drawn without scratches, and the life expectancy tends to be longer. |
| α(sw)Exit | The deepening of the outlet can greatly support the tensile stress of the outlet. |
| The best material depends on the wire you draw and the quantity you draw. Contact us to help you choose the most economical solution and reduce the total cost of ownership of your drawing dies. | |
