Why Choose Tungsten Carbide for Carbide Slitter Knives?

  1. Exceptional wear resistance & long life – Tungsten carbide stands up to abrasion far longer than standard steels, ensuring consistent slit edge quality and fewer replacements. 

  2. Precision edge & clean‑cut finish – Advanced grinding and polishing deliver mirror‑finish edges that reduce friction, minimize burrs and deliver optimal slit quality. 

  3. High hardness with toughness – Modern carbide grades combine hardness with impact resistance, making them well‑suited for high‑speed slitting of films, foils and composite materials. 

  4. Cost‑effective in high‑volume production – While upfront cost may be higher than conventional steel knives, the reduced downtime, extended service life and lower scrap rates deliver better total cost of ownership.

Custom Specifications & Sizes

We offer comprehensive customisation so you can match the exact requirements of your machine setup and material type:

  • Outer Diameter (OD), Inner Diameter (ID) and Blade Thickness – tailored to your machine model
  • Hole patterns (number of holes, hole diameter) or solid blades
  • Grades of tungsten carbide (grain‑size, cobalt binder %, hardness) selected based on material and process
  • Edge geometry, bevel type, coating or surface finish (optional TiN, mirror polish)
  • Rapid prototyping, drawing review and full mechanical drawings approval

Through this customisation, we ensure seamless integration of your blades into your processing line and maximise blade life while maintaining cut quality.

Quality Assurance & Service Support

Our manufacturing and quality control practices ensure that every carbide slitter knife meets stringent performance standards:

  • Premium virgin tungsten carbide material and controlled micro‑structure
  • Precision grinding, mirror‑finish edges and quality testing (hardness, flatness, surface roughness)
  • ISO‑certified workflows and full traceability from raw material to finished blade
  • Global shipping, quick‑turn custom manufacturing and technical support teams ready to advise on blade selection, maintenance and re‑grinding
  • After‑sales service: blade re‑sharpening, refurbishment and spare parts supply

How to Order & Get a Quote

  1. Send us your blade drawing (OD, ID, T, holes) or machine model and material type.
  2. Our engineering team reviews your requirements and suggests the optimal carbide grade, edge finish and economic solution.
  3. We provide a formal quotation including lead‑time, shipping terms and any customisation cost.
  4. Once approved, we manufacture, test and ship the blades. You receive packing list and QC report before dispatch.
  5. Support ‑ we help you monitor performance, schedule re‑grinding or replacement and optimise total cost of ownership.
