Shredder blades drive throughput, cut consistency, and downtime. We make custom/OEM knives for single-, dual-, four-shaft and granulator shredders, plus spacers for stable stacks.
Shredder blades for heavy-duty, contaminated feedstocks—steel grade, heat treatment, and edge geometry selected to resist chipping, handle shock loads, and maintain consistent cutting in shredding lines.
PET, HDPE, PP, mixed plastic waste
Mixed scrap feed and scrap processing lines
hardwood, residuals, off-cuts
volume reduction and heavy-duty shredding
Harder or more abrasive materials require higher wear resistance and, in some cases, carbide-tipped or coated options (e.g., fiber-filled plastics).
Single-, double-, and multi-shaft systems require different geometry and mounting specs (OD/ID/thickness, hole pattern, keyway, etc.).
Knife spacing (clearance) and cutting angle affect particle size, machine load, and stability.
Higher speed and mixed feedstock demand stronger materials and a planned sharpening/replacement schedule.
Lower initial cost may increase downtime, energy use, and replacement frequency. A properly selected knife set often reduces total operating cost.
We select materials and manufacturing routes based on real shredding conditions:
To extend knife life and reduce unplanned downtime, we provide:

Not recommended. Mixed-metal scrap is highly abrasive and may require higher wear resistance or carbide options to avoid rapid edge deterioration.
It depends on feedstock abrasiveness, contamination, shaft speed, and clearance setup. Share your runtime and wear photos—we’ll recommend a practical service interval.
We support OEM replacement by drawing, sample, or key dimensions (OD/ID/thickness, mounting pattern). Brand is helpful but not required.
Yes. We offer re-grinding programs, service kits, and guidance to reduce unplanned downtime.
