Standard sizes we commonly produce
Every blade is made to your drawing, but these are the ranges we run routinely. Use them to check fit before you send a request—custom dimensions outside this range are still welcome.
| Parameter | Typical range | Notes |
|---|---|---|
| Length | 40–4000mm | Longer sizes on request |
| Width | 40–800 mm | Square and rectangular profiles |
| Thickness | 8–400 mm | Single or multi-hole plates |
| Bore / mounting hole | Ø8–Ø100 mm | Countersunk or straight |
| Hardness | HRC 52–62 | Set to feedstock and impact level |
| Weight (per blade) | 0.2–300 kg | Depends on geometry |
| Dimensional tolerance | ±0.02 mm | On reviewed critical dimensions |
| Edge angle | 30°–90° | Selected for the cutting application |
Typical values are for reference. Final dimensions and tolerances are confirmed against the approved drawing.
Choose your blade steel by feedstock
Tell us what you are shredding and we will match steel grade, hardness and heat treatment to the operating conditions.
| Feedstock | Suggested steel | Hardness | Priority |
|---|---|---|---|
| Rigid and film plastics | D2 / SKD11 / Cr12MoV | HRC 58–62 | Wear resistance |
| Wood, pallets and branches | SKD11 / 9CrSi | HRC 56–60 | Edge retention |
| Tyres and rubber | DC53 / SKD11 | HRC 56–60 | Toughness and wear |
| Metal and e-waste | H13 / application alloy | HRC 52–56 | Impact toughness |
| Paper, cardboard and textile | D2 / 9CrSi | HRC 58–60 | Clean fine cut |
| Municipal solid waste | Application-specific alloy | HRC 54–58 | Mixed and abrasive feedstock |
Final steel and hardness are confirmed after technical review of feedstock, contamination, impact and required service life.
Send your machine model, we match the blade

Capability & quality assurance
A replacement-parts supplier is only as good as its consistency. These controls stand behind every approved order.
Reviewed critical-dimension capability
Production area
Export countries
Spectrometer check
Steel composition verified against the specified grade before machining.
Rockwell testing
Post heat-treatment hardness confirmed to the approved target HRC.
Dimensional inspection
Critical dimensions and edge finish checked against the approved drawing.
Capabilities and documentation are confirmed according to the product, drawing and order requirements.
Sampling, MOQ & logistics
Practical details buyers ask before quoting, explained before you place an order.
Trial order available
Sample and small trial quantities are available so fit and wear life can be validated before volume production.
Flexible minimum
Low quantities are supported on standard geometries; special profiles are reviewed case by case.
Confirmed on order
Typical production is 15–30 days after drawing, material, quantity and commercial terms are approved.
EXW / FOB · anti-rust packing
Common Incoterms are supported. Blades are protected against rust and packed for export.

Frequently asked questions
Can you manufacture blades from our drawing?
Yes. We accept PDF, DXF, DWG, STEP files and physical samples.
Can you identify a blade from the machine model?
Yes. Send the machine brand, model, original part number and clear photos for review.
Which blade materials are available?
Common options include D2, SKD11, DC53, HSS and application-specific alloy steels.
How do you recommend hardness?
Hardness is selected according to feedstock, impact load, wear conditions and required toughness.
What dimensional tolerance can you achieve?
Critical dimensions can typically be controlled up to ±0.02 mm, subject to blade size and drawing review.
Can you supply a trial quantity?
Yes. Prototype and small trial batches are available before volume production.
What is the normal lead time?
Typical production takes 15–30 days after drawing and order confirmation.
How is product quality inspected?
We verify material, hardness, dimensions, surface condition, cutting edge and final quantity before release.
Do you manufacture official OEM parts?
No. WALI supplies independently manufactured compatible replacement blades and does not imply official affiliation.
How should we request a quotation?
Send the drawing or dimensions, material, quantity, machine model and required delivery date.
Match your drawing.
Include blade dimensions, material, quantity, machine brand/model and target delivery date.
