• Tungsten carbide cold heading dies can ensure that screws and nuts achieve extremely high dimensional accuracy and shape consistency, and the tolerance can be controlled within a very small range, meeting the application scenarios with high precision...

Design a special tungsten carbide cold forging mold according to the specific shape, size and precision requirements of special-shaped screws and nuts. The mold cavity should accurately match the product shape, including the threaded part (usually an approximate shape reserved for subsequent thread rolling or thread...

First, the raw materials required for the production of nuts, usually disc-shaped metal wires (such as carbon steel, stainless steel, etc.), are delivered to the starting station of the machine through an automatic feeding device. The feeding device can ensure that the wire enters the processing flow continuously, s...

• It is an tungsten carbide material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Common hard compounds include tungsten carbide (WC), titanium carbide (TiC), etc., and the bonding metal is generally cobalt (Co...

 Carbide rollers have high thermal conductivity and good heat dissipation effect. During the cold rolling process, the friction between the rollers and the steel bars will generate a lot of heat. Good thermal conductivity can quickly transfer the heat, reduce the temperature of the roller surface, reduce the th...

First, according to the specifications, size, shape and other requirements of the required nuts, the overall structure of the four-station tungsten carbide nut mold is designed, including the specific functions and shapes of each station. For example, some ...

The carbide mold itself has the characteristics of hardness and brittleness. If it is used for large-surface shrinkage and drawing, it is easy to cause the mold to break and scrap due to the stress it can withstand. Even the best mold will be damaged and fail under long-term work and high temperature. If the mold su...

1. Raw material preparation: • Powder selection: Select tungsten carbide powder and binder powder. The binder is usually cobalt powder (a small amount of other hard phases or alloy elements can also be added as required). The particle size, particle size...

YG15 and YGH30 cemented carbides have high hardness and can withstand high pressure during cold rolling without deformation. This helps to ensure that the rollers maintain good shape accuracy during long-term use, thereby ensuring the dimensional accuracy and surface quality of the cold-rolled products.

• High hardness and high strength: The hardness of cemented carbide material is much higher than that of ordinary steel, which makes the mold have strong wear resistance and deformation resistance, and can maintain good precision and stability during long...

Metallographic testing is a method for observing the metallographic microstructure of tungsten material products, involving a metallographic method for observing the microstructure of tungsten products by chemical corrosion. It includes grinding, grinding and polishing the surface of tungsten material products.Metal...

• Main metal content: For example, for tungsten carbide cobalt cemented carbide, it is necessary to ensure that the content of tungsten carbide and cobalt is within the specified range, because the ratio of these two main components directly affects the performance of cemented carbide.
