Nepal’s manufacturing sector is undergoing an expansion, driven by structural growth in food packaging, post-consumer plastic recycling (primarily in Kathmandu, Pokhara, and the Terai industrial belt), and domestic paper converting mills. In these demanding environments, standard carbon steel and low-alloy tool blades wear down rapidly, causing frequent line stoppages, product deformation, and high tool replacement budgets.
The import of top-tier industrial knives has traditionally faced logistics and supply bottlenecks. Sichuan Shen Gong addresses this gap by offering direct-factory engineering and custom tungsten carbide blanks optimized specifically for Nepalese industrial machinery. By introducing sub-micron grain structures and specialized cobalt binders, our blades resist micro-chipping caused by contaminated recycled plastics and abrasive agricultural fibers.
How Sichuan Shen Gong combines sub-micron powder formulations and advanced sintering techniques to deliver superior cutting tool performance.
Our powder preparation utilizes 100% virgin tungsten carbide powder with grain sizes ranging from 0.2μm to 0.6μm. This fine dispersion provides a uniform matrix hardness up to 92.5 HRA, delivering exceptional abrasive wear protection against paper and synthetic polymers.
All carbide blanks are sintered inside computerized HIP furnaces operating at temperatures up to 1450°C and gas pressures up to 100 bar. This method eliminates microscopic void spaces and porosity, reducing the risk of sudden brittle fracture under high load.
Through precision multi-axis CNC grinding and diamond polishing, we achieve surface roughness (Ra) down to 0.02μm. This mirror-like surface finish significantly reduces friction, prevents adhesive buildup, and guarantees exceptionally clean cuts.

Technical guidance and commercial support information for procurement officers in Nepal.
Tungsten Carbide offers up to 10 times higher wear resistance and twice the Young's modulus compared to standard High-Speed Steel. Under high-speed or abrasive conditions—such as cutting recycled polymers or thick corrugated paperboard—carbide blades maintain their cutting edge significantly longer, reducing structural burrs and tool change stoppages.
We leverage robust trans-Himalayan shipping networks, transporting orders overland via the Lhasa-Tatopani or Rasuwagadhi border crossings directly to Kathmandu. For fast-track orders, we ship via air cargo from Chengdu (CTU) to Kathmandu (KTM) within 5 to 7 business days, providing complete customs clearances and certificates of compliance.
Yes. Our in-house research laboratory specializes in adjusting raw powder formulations. By varying the binder content (Cobalt or Nickel) from 6% to 15% and modifying the carbide grain sizing, we can tailor the properties for high-impact applications (like plastic recycling granulators) or high-wear applications (like thin film slitting).
Sichuan Shen Gong runs under an ISO 9001 certified quality control framework. Each batch of tungsten carbide undergoes strict metallurgical verification, ultrasonic crack detection, and coordinate measuring machine (CMM) dimensional checks prior to shipment.
