Our Manufacturing & Quality Assurance

We operate an advanced manufacturing facility with CNC grinding, surface grinding, induction hardening and laser measurement. Each knife undergoes dimensional inspection, edge finish verification and material composition testing. We stand behind our blades with a quality assurance program and global logistics support.

How to Order & Next Steps

  1. Provide your machine brand, model, blade OD/ID/thickness, material or existing OEM part number.
  2. Tell us your web material (film, foil, paper, non‑woven), speed, line width and any known issues (edge burr, dusting, slit defects).
  3. We will propose a specification, milling drawing and quote.
  4. Once approved, we manufacture, inspect and ship – with global delivery and support.
  5. For service and optimisation, we can schedule resharpening or blade replacement programmes.

Why Yishi Machinery Stands Out

  • Over 8 years experience in industrial blades and custom knife design. 
  • In‑house factory (3000 m²) and access to advanced tool‑steel and carbide materials.
  • Dedicated engineering team for blade optimisation, not just standard off‑the‑shelf supply.
  • Worldwide shipping and support for OEMs, distributors and end‑users.
