Shield Cutters (TBM) Cutter, Disc Cutting & Cutter Rings: Material: tungsten carbide: pressing and sintering by high-quality double-crystal carbide selected by our company, which could maintain good welding properties and wear resistance, as well as having a higher impact resistance. Steel body: made by high-quality raw materials - steel material. After the heat treatment process, the original high-quality steel material could be forged to high-performance equipment materials, with hardness up to 51-55HRC and impact toughness above 60J. This material has good ductility and hardness, and has effects of overcoming extreme conditions. Braze welding: welding techniques are introduced from Northern Europe, allowing the interpenetration of alloy and alloy composition in steel body, achieving high welding strength. Build-up welding: our company could use laser, plasma cladding, CO2 arc welding, argon arc welding, etc.

We use raw material of high-grade cleanliness in order to ensure the best sintering ability.Carbon tungsten and cobalt are mainly bought from European.This expensive but high-quality raw materials are the basis of our tools to achieve first-class quality.
In order to ensure the quality of products, we do not use recycled materials. As different uses require different quality of cemented carbide,
our products are designed to ensure both the degree of wearing resistance and the necessary rigidity.
Cutting Picks (Bits) & Holder material: made by high-quality raw materials - steel material

In the perspective of professionals, consistency crystal structure, minimal impurities and maximum cleanliness are signs of cemented carbide. While the users are interested in the product’s abrasion resistance and wear FIG.
Hardness
The mixing of the raw material powder and the size of crystalline particles determines the hardness of sintering tools. In the case of hardness fitting the processing tasks, the wearing degree is small.
Breaking strength
If the tool is broken, indicating poor quality of carbide or unfitting of tools. The highest quality products as well as our recommendation and help in the tool selection process could prevent the occurrence of this phenomenon.
Abrasion resistance
In addition of the high abrasion resistance, the cemented carbide should also have sufficient rigidity. Different uses require different hardness and rigidity performance.
Starting from raw material storage, to spray drying and pressing until sintering, quality control runs through the cemented carbide process. All details of the production process are optimized and monitored, and making further improvements if necessary. Practical experience always affects the improvement process.
Production Process
The compounding ratio of raw material is determined and humidification rolling is processed based on customer’s requirements to the cemented carbide quality. Under the effect of burning gas stream in the spray tower, flowing carbide powder can be formed. Then electronically pressing is conducted. When the cemented carbide powder is pressed into the so-called mushroom-shape, the density has reached 50% of the final density. In the vacuum oven and sintering equipment with sintering temperature over 1450℃, its superior characteristics are formed after sintered. This kind of professional knowledge and practical experience dependence processing technique creats the high-quality cemented carbide.
