Carbide rods are mainly used to make drills, end mills, and reamers. It can also be used to make cutting, punching and measuring tools. Tungsten carbide rods have stable mechanical properties, high wear resistance, impact resistance, and are easy to weld. They are widely used in the production and processing industry to make the required tools, such as: micro drill bits in the PCB industry, electrode rods in the optoelectronic communication industry , Mechanical processing industry tungsten steel drill bits, drill handles, push rods, wear-resistant precision parts.
Features of Langsun Carbide's Carbide Rods:
1. It has high strength and high hardness.
2. Good wear resistance, high bending strength.
3. Good chemical stability, corrosion resistance, low thermal expansion coefficient.
4. Vacuum high-temperature and high-pressure sintering reduces internal voids and greatly improves product performance.
5. Use scientific and advanced production equipment for standardized production to ensure quality.
6. Manufactured from 100% pure raw materials.
Production process of cemented carbide rod:
1. High-purity raw materials are used to reduce and produce high-purity tungsten powder
2. Choose different molds for pressing according to different purposes
3. Low pressure sintering to make blank
4. Fine grinding and polishing (this step is not required if the customer needs a blank)
