Established in 1998 in Chengdu, Sichuan, Shen Gong has spent over 25 years evolving from a specialized workshop into a global leader in cemented carbide industrial blades. As a national high-tech enterprise, we oversee the entire production chain—from RTP (Ready-to-Press) powder manufacturing to finished high-precision cutting tools.
Our commitment to excellence is backed by ISO9001 certification, ensuring that every aluminium cutting disc and slitting knife meets stringent international quality standards. We specialize in WC-based (Tungsten Carbide) and TiCN-based cermet technologies, providing a level of durability and precision that is unmatched in the industry.
The global demand for High-Quality Aluminium Cutting Discs has reached unprecedented levels, driven by the rapid expansion of the electric vehicle (EV) market, the renewable energy sector, and advanced aerospace manufacturing. Aluminium, known for its exceptional strength-to-weight ratio, has become the material of choice for engineers worldwide. However, slitting and cutting aluminium—especially thin foils and silicon steel sheets—requires specialized tools that can withstand high-speed friction while maintaining a burr-free edge.
In the current industrial scenario, the transition from traditional High-Speed Steel (HSS) to Cemented Carbide is the most significant trend. Carbide blades offer a service life that is up to 20 times longer than HSS, reducing downtime for factory tool changes and significantly lowering the total cost of ownership. For an Aluminium Cutting Disc Factory, the challenge lies in producing a blade that is hard enough to resist wear but tough enough to avoid chipping during high-impact industrial processes.
Global procurement teams in regions like Europe, North America, and Southeast Asia are increasingly looking for reliable Chinese factories like Shen Gong. The reason is twofold: first, the maturity of the Chinese tungsten supply chain allows for competitive pricing; second, the technological leap in Chinese manufacturing means that "Made in China" now equates to "Precision Engineered." Our blades for aluminium foil manufacturing are engineered to prevent material adhesion, a common problem when cutting non-ferrous metals where heat can cause the aluminium to "smear" onto the blade edge.
Furthermore, the Industry 4.0 revolution is reshaping how factories operate. Automation in the Li-ion battery production line, for instance, requires blades with mirror-finish edges. Any microscopic notch on a slitting knife could cause a short circuit in the battery cell. Shen Gong was the first in China to address this, developing precision slitting knives with zero-notch mirror finishes specifically for battery electrodes. This localized innovation has now become a global benchmark, used by major battery manufacturers in Germany, Japan, and the USA.
Sustainability is also a key driver. Shen Gong doesn’t just sell tools; we offer a Knives Recycling and re-sharpening service. By cherishing finite resources, we help our partners reduce their carbon footprint while maintaining a sharp edge in their production. This circular economy approach is what distinguishes a mere supplier from a strategic partner.
Production is carried out in accordance with the ISO quality system, effectively ensuring stability between batches. Simply provide your samples to us, we do the rest.

When searching for an Aluminium Cutting Disc Factory, reliability and consistency are paramount. At Shen Gong, we differentiate ourselves through our integrated manufacturing model. Unlike many competitors who outsource their raw materials, we produce our own WC-based cemented carbide RTP powder. This allows us to control the purity and grain size of the material from the molecular level, ensuring that every batch of knives has the exact same hardness and fracture toughness.
For semi-finish to finish machining of steel parts, we provide TiCN-based cermet cutting tools. These tools exhibit an exceptionally low affinity with ferrous metals, which translates to a superior surface finish that often eliminates the need for subsequent grinding processes. This technology is a game-changer for factories looking to streamline their production lines and reduce processing steps.
We recognize that an industrial knife used in a food processing plant in North America has different requirements than a corrugated cardboard factory in Southeast Asia. Our sales team is not just multilingual; they are technically trained to understand these localized application scenarios. Whether it is anti-adhesion treatments for packaging or dust suppression for paper slitting, we provide a customized solution rather than a one-size-fits-all product.
Every blade that leaves our factory undergoes a multi-stage inspection process. We utilize laser interferometers and digital microscopic analysis to verify edge straightness and symmetry. This level of scrutiny is why our products have successfully replaced high-end European and Japanese brands in some of the most demanding factories worldwide. Our mission—"Make Sharp Edge Always In Reach"—is a promise of quality that we have kept for over two decades.
