Tungsten Carbide Anvil & Cylinder for Synthetic Diamond
T&D supplies dies, punches, anvils, and backup blocks tailored to your exact dimensional needs. Our products are designed to withstand pressures of up to one million psi, pushing the boundaries of mechanical properties in tungsten carbide materials.
Cemented Carbide Anvil and Cylinder for Synthetic Diamond Manufacturing
Widely utilized in the artificial diamond powder industry, our anvils and cylinders perform seamlessly under 60,000Mpa pressure conditions. We can assure each product is crafted to the highest quality standards, available in both finished and as-sintered options. Leveraging advanced pressing, sintering technology, and HIP, our manufacturing process eliminates any flaws such as pores and cracks.
At T&D, we specialize in accommodating custom requests, offering customized grades and sizes to match your specific requirements and usage conditions.
