  • Fully Custom
  • Expedited Production Processing

Precision-ground chemical fiber cutting blades from YISHI are engineered for high-volume synthetic fiber processing lines. Manufactured from D2 and SKD11 tool steels with vacuum heat treatment to HRC 58–62, these shear blades deliver consistent, clean cuts with minimal burring across polyester, nylon, acrylic, and polypropylene tows. Whether you operate staple fiber cutters, tow converters, or recycling shredders, our blades are available in a wide range of standard dimensions and can be fully customised to match your OEM specifications. With thickness tolerances of ±0.005mm and a choice of mounting slots or holes, YISHI blades help reduce downtime and fibre waste in continuous production.

3-Hole Razor Blades

The three-hole configuration is the standard mounting format for chemical fiber staple cutter blades. Three precision-ground through-holes locate the blade onto corresponding pins or bolts in the cutter rotor, enabling fast, repeatable blade changes with zero lateral drift.

Our 3-hole razor blades are available in the standard dimensions listed below and can be manufactured to your drawing for OEM compatibility with Neumag, Fleissner, and Barmag fiber cutters.

Frequently Asked Questions

  • What steel grade is best for cutting polyester fibers?

    For standard polyester fiber cutting, we recommend D2 (Cr12MoV) tool steel hardened to HRC 58–62. It offers an excellent balance of wear resistance and toughness. For high-volume, abrasive fibers such as recycled polyester with contaminants, we may suggest HSS M2 or tungsten carbide inserts for extended blade life.

  • Can you replicate blades from existing samples?

    Yes. Customers can send a used blade or a dimensioned drawing. We reverse-engineer critical features like slot placement, hole patterns, and bevel angles to produce a direct replacement. We also reference OEM manufacturer part numbers when available to confirm interchangeability.

  • What is the typical lead time for custom chemical fiber blades?

    Standard lead time is 15 working days from drawing approval. For repeat orders and stock sizes, we can often dispatch within 7 days. Express service is available for urgent requirements.

  • How do I determine the right bevel angle for my fiber?

    The bevel angle depends on fiber type and cutting speed. Soft, fine fibers typically require a sharper angle around 20–25°, while coarse or technical fibers like aramid need a more robust edge at 35–45°. Our engineers can recommend an angle based on your process parameters.

  • Do you offer re-sharpening services?

    Yes, we provide re-grinding services for our blades to original specifications, including thickness, parallelism, and edge sharpness. This can extend blade life by several cycles, reducing total cost of ownership.

  • What mounting configurations do you support?

    We support a wide range: plain (no holes or slots), through holes (circular), slotted holes (obround), counterbored holes, and end slots. Common patterns include single slot, double slot, and triple hole arrangements as shown in our standard size list. Custom patterns are accepted based on your drawing.
