Tungsten Steel Bars can be classified into tungsten steel bars for PCB, solid tungsten carbide bars, single hole tungsten steel bars, double hole tungsten steel bars, double spiral hole tungsten steel bars, triple spiral hole tungsten steel bars, etc. According to the molding process, it can be divided into extrusion molding and molding molding. The difference is that the extrusion rod has beautiful appearance and is easy to grind; The advantage of molding rod is that the density is relatively uniform, but it is not conducive to grinding.

1. Using low-pressure sintering technology, the quality is stable and reliable: the maximum sintering pressure can reach 100kg/F, which can effectively eliminate the internal pores of the alloy, and obtain a blank with high hardness, high strength and good densification. The advanced temperature control system can effectively reduce quality fluctuations.
2. With automatic pressure relief extrusion equipment, various types of bars can be produced: the pressure can be adjusted according to different requirements, which is beneficial to the production of different types of bars.
3. High-precision grinding of the bar material can achieve the mirror effect: using a CNC grinder, the polishing speed is the largest, and the damage layer can be quickly removed during polishing, and the surface finish can be improved to achieve the highest mirror effect.
Tungsten steel bars are kind of ultra-fine grained tungsten steel material. This tungsten steel rod has the characteristics of high hardness, good bending strength, wear resistance, not easy to collapse, and not easy to break. It is a special material for micro-drills, which is widely used in tungsten steel milling cutters, engraving knives and wear-resistant parts.
