More Detail Information About Tungsten Carbide Punching Dies 

The carbide dies have excellent concentricity, parallelism, perpendicularity, The carbide punch manufactured by XYMJ has excellent performance,  outside diameter, inner diameter, the height of which, are all accurate grinding, tolerance within 0.01mm, mainly used for piercing by machinery manufacture & hardware, the finished holes are free of burrs and own precise size.

Customized products can be supplied according to specific details. Complete interchangeability of our carbide dies components is guaranteed.

Factors To Consider For Designing Carbide Dies
1. It must have a high yield, good structural shape with high dimensional accuracy.
2. If necessary, all the bottom and upper of the carbide dies should use tungsten carbide through the analysis of the most worn parts. In some cases, you can adopt tool steel and tungsten carbide in combination under the situation that has punch difficulty processing or fixed in order that the mould manufacturing and application must be the most reasonable and economical. 
3.Under the allowed processing conditions of tungsten carbide die, the mosaic structure is more economical, easy to process and repair.
