North Korea’s industrial landscape is increasingly focused on the modernization of its metallurgical and heavy industry clusters. From the Kim Chaek Iron and Steel Complex to the Chollima Steel Complex, the demand for precision cutting tools that can withstand high-volume processing of silicon steel, carbon steel, and non-ferrous alloys is at an all-time high. In this context, "Metal Sheet Knives" are not merely consumables; they are critical components in the supply chain of infrastructure development.
As the region looks toward optimizing its self-sufficiency in manufacturing, the adoption of Tungsten Carbide (WC) and TiCN-based Cermet tools represents a significant technological leap. These materials offer the hardness required to maintain edge integrity over thousands of cycles, reducing the downtime that traditionally plagues older machinery using standard HSS (High-Speed Steel).
Sichuan Shen Gong Carbide Knives Co., Ltd. stands as a titan in the cemented carbide industry. Located in Chengdu, the high-tech heart of Southwest China, we have dedicated over two decades to the research, development, and vertical integration of industrial cutting solutions.
Our unique advantage lies in our Full-Process Control: from RTP (Ready-To-Press) powder formulation to vacuum sintering and precision CNC grinding. This ensures that every blade exported to global markets—including the demanding industrial sectors of North Korea—meets stringent ISO9001 standards for stability and performance.

In the North Korean heavy industry sector, where raw materials like iron ore and coal are abundant, the local production of sheet metal requires knives that can endure extreme heat and friction. SHEN GONG offers a multi-tier technical roadmap to address these challenges:
Ideal for general slitting of steel coils. Our WC-based knives feature a sub-micron grain structure that balances toughness (preventing chipping) with extreme hardness (preventing wear). This is essential for the heavy-gauge metal sheets used in North Korea's railway and shipbuilding industries.
For semi-finish to finish machining, our Cermet tools provide a very low affinity with ferrous metals. This prevents "Built-Up Edge" (BUE) and results in a mirror-like finish on the cut surface, critical for manufacturing precision components in the Pyongyang electronics or automotive sectors.
Our proprietary ETaC-3 coating technology reduces the coefficient of friction, allowing for high-speed slitting without the need for excessive lubrication, thereby increasing efficiency and reducing operational costs in local North Korea factories.
High-toughness blades for North Korea's growing industrial waste management and rubber recycling plants.
Precision coil slitting for motor manufacturing and silicon steel sheet production in local heavy complexes.
World-leading corrugated slitter scorer knives for packaging plants supporting domestic logistics.
Specialized slitting knives for Li-ion battery electrodes, supporting energy independence projects.
Operating in a complex global market requires more than just high-quality products; it requires Reliability and Compliance. SHEN GONG’s logistics and sales teams are experienced in the nuances of international trade, ensuring that documentation, quality certifications, and delivery timelines are met with precision.
Our CNC machining capabilities allow us to achieve tolerances that are virtually unmatched in the region, ensuring that North Korea’s industrial machinery operates at peak performance without vibration or edge misalignment.
Our sales team provides 24-hour response cycles, offering technical consultation in multiple languages to bridge the gap between engineering requirements and final production.
Depending on the material being cut (e.g., silicon steel vs. aluminum), a Shen Gong carbide knife typically lasts 10-20 times longer than traditional HSS blades. This significantly reduces the frequency of tool changes in continuous production lines common in North Korea’s industrial zones.
We use a mirror-grinding process that achieves a notch-free edge visible only under 200x magnification. This prevents material buildup and ensures clean, burr-free edges on foils as thin as 6 microns.
Yes. Our OEM service is specifically designed to accommodate legacy machines. By providing a technical drawing or a physical sample, we can replicate or improve upon the original blade specifications using modern carbide materials.
