Globally, the plastic pelletizing market is experiencing a paradigm shift. With increasing environmental regulations in the EU and North America, the demand for recycled polymer granules has skyrocketed. Pelletizing knives are the heart of this transformation, ensuring that waste plastic is efficiently converted into high-quality raw material.
Modern industrial systems have transitioned from traditional tool steel to Tungsten Carbide and TiCN-based cermet. These materials offer 10-20 times the wear resistance, which is crucial for underwater pelletizing systems where downtime can cost thousands of dollars per hour.
The global trend is moving towards fully automated granulation lines. This requires pelletizing knives with extreme geometric precision—often within micron-level tolerances—to ensure consistent pellet size and reduce the production of "fines" or "dust" that degrades batch quality.

Sichuan Shen Gong Carbide Knives Co., Ltd. was established in 1998. Located in southwest of China, Chengdu, Shen Gong is a national high-tech enterprise specializing in the research, development, manufacturing, and sales of cemented carbide industrial knives and blades for more than 20 years.
Shen Gong boasts complete production lines for WC-based cemented carbide and TiCN-based cermet, covering the entire process from RTP powder making to the finished product. Our ISO9001 certified facility ensures consistent batch quality for global clients.
Global enterprises are diversifying their supply chains. As a China-based factory, Shen Gong offers a robust alternative to high-priced European brands without compromising on metallurgical quality or precision.
Standard solutions often fail in specialized recycling applications. We provide OEM production based on specific chemical fiber or plastic compositions, adjusting carbide toughness and hardness to match the material's abrasiveness.
Modern procurement includes a "Green" mandate. Shen Gong addresses this by offering Knives Recycling and re-sharpening services, helping clients reduce waste and improve their ESG scores.
Integrated Production: From RTP (Ready-To-Press) powder to final mirror grinding, we control every step. This ensures metallurgical integrity that middleman suppliers cannot guarantee.
Cost-Efficiency: Located in Chengdu, the hub of China's carbide industry, we leverage local expertise and raw materials to provide premium quality at competitive pricing.
R&D Strength: Our team doesn't just make knives; they provide cutting solutions. We analyze material properties to prevent edge chipping in high-impact recycling environments.
Global Logistics: Strategic partnerships with global couriers ensure that your replacement blades arrive within days, reducing potential line downtime.
