Introduction
Sichuan Shengong Carbide Knives Co., Ltd. is a Chinese manufacturer of cemented carbide industrial knives and blades headquartered in the Southwest Airport Economic Development Zone in Shuangliu District, Chengdu, Sichuan Province. Founded in 1998, the company focuses on the research, development, and production of carbide-based cutting tools, with applications spanning packaging, new energy, metal processing, recycling, medical, food processing, and plastics-related converting operations.
The company is positioned as a specialized industrial knife maker rather than a broad plastics processor. Its relevance to the plastics industry lies mainly in the supply of slitting, trimming, and cutting knives used in converting lines, packaging machinery, foil and film slitting, and other precision-cutting applications adjacent to plastics manufacturing and packaging supply chains. According to company materials, it has built a portfolio of 200+ product types, more than 40 patent-related claims or patents by its own account, and exports a substantial share of output to overseas markets.
History and Development
Sichuan Shengong was established in 1998 in Chengdu and has since developed from a domestic industrial knife producer into an exporter serving multiple industrial markets. Company materials state that it has been engaged in tungsten carbide knife production for more than 20 years, with a gradual expansion from basic industrial blades into a wider range of precision cutting tools.
Key development milestones include:
- 1998: Company founded in Chengdu, Sichuan.
- 2000s onward: Expansion into export markets and broader industrial applications, with company materials reporting overseas sales to more than 40 countries and regions.
- Recent years: Recognition as a national high-tech enterprise and listing as a Sichuan “gazelle” enterprise, reflecting technology-oriented positioning in the province’s industrial ecosystem.
Public industry and exhibition listings also show the company as an active participant in the global industrial tooling and packaging machinery supply chain, including appearances on ChinaPlas-related exhibitor records.
Business Operations and Segments
The company’s business is centered on the manufacture and sale of industrial knives, circular blades, and custom cutting tools. Its operations appear organized around precision wear-resistant tooling rather than consumer products.
Major operational characteristics include:
- Manufacturing focus on tungsten carbide and cermet-based cutting tools.
- OEM/ODM-style customization, including products made to customer specifications and machine interfaces.
- Export orientation, with company sources indicating that more than 70% of products are sold overseas in some descriptions.
- Serving multiple downstream industries, which reduces dependence on any single end market.
The company’s business model is closely tied to equipment uptime and cutting performance, since customers in packaging, metal slitting, and converting operations require blades with high wear resistance, dimensional accuracy, and stable edge retention.
Products and Technologies
Sichuan Shengong’s product range includes a broad set of carbide blades and industrial knives, such as:
- Circular slitter knives
- Slitting and stripping knives
- Bottom knives for rewinding and slitting lines
- Three-hole blades
- Film slitting blades
- Corrugated board knives
- Shear and rotary blades
- Custom-shaped industrial blades
The company states that it has a complete production line covering WC-based cemented carbide and TiCN-based cermet materials, beginning from powder preparation through fine grinding. It also describes use of spray pressing equipment, high-density raw materials, mirror polishing, and precision finishing to support tight tolerances and surface quality.
Technically, these attributes matter because industrial blades used in high-speed converting lines must resist:
- Abrasive wear
- Edge chipping
- Thermal and mechanical stress
- Dimensional drift during continuous operation
Company materials specifically note that its corrugated-paper slitting circular knives have performance suited to high-speed slitting equipment. The product range is also designed for machinery from multiple international and domestic brands, including corrugated and slitting systems used in packaging production.

The company’s documented end markets include the following:
- Packaging and corrugated board converting
- New energy and lithium-battery-related manufacturing
- Metal processing and steel slitting
- Recycling and energy recovery
- Medical products
- Food processing
- Plastics and film converting
- Paper, printing, and tobacco-related cutting operations
Within the plastics value chain, the most relevant applications are in:
- Film slitting
- Packaging line cutting
- Converting machinery
- Foil and composite material trimming
- Precision slitting for polymer-based webs and laminates
This makes the company an upstream supplier to manufacturers that require durable cutting components to process flexible materials, including plastics, paper-plastic laminates, and packaging substrates.
Global Presence and Market Position
Sichuan Shengong is based in Chengdu and operates as an export-oriented manufacturer with sales channels for both domestic and overseas customers. Company materials say that a majority of output is exported and that the firm serves customers in more than 40 countries and regions.
Its market position is best understood as that of a specialized industrial knife manufacturer with a strong presence in carbide-based blades rather than a mass-market metalworking conglomerate. The company’s participation in international sourcing platforms and trade listings indicates integration into global B2B procurement networks serving packaging machinery, converting equipment, and industrial processing sectors.
Sustainability and Environmental Initiatives
Publicly available information on the company’s sustainability program is limited. The available materials emphasize product durability, long service life, and precision manufacturing, which can indirectly support resource efficiency by reducing blade replacement frequency and downtime.
At the same time, carbide-tool manufacturing is material- and energy-intensive, and the environmental profile depends on powder metallurgy, grinding, polishing, and waste handling practices. No detailed public disclosure in the provided sources describes emissions targets, lifecycle assessments, or formal circular-economy programs, so any assessment of sustainability performance should be treated cautiously.
