Knife factory & supplier — plastic recycling, shredding, wood
Crusher, shredder & chipper knives — from our factory to your line
We manufacture and supply replacement industrial blades for plastic recycling plants, small wood yards, traders, and parts shops. Send photos or a drawing—we tell you if we can match it and when it can ship.
Samples in the photos are from our workshop floor. Pick a close shape in the catalog, then message us with ruler photos—first-time import is fine.
Factory & catalog samples
How a real knife factory backs small buyers
We work with plants and dealers who care about uptime and margin—not glossy brochures.
Manufacturer, not a trading maze
You talk to people who know grinding and heat treatment. One thread for sizes, steel, and commercial terms—no endless forwarding.
Exporter paperwork in plain words
Invoice, packing list, and HS heading for steel knives stated up front. If you never imported from China, we explain the usual steps so your customs broker is not guessing.
Honest limits
If a photo is too blurry to guarantee fit, we say so. If lead time stretches because of heat-treat queue, we say that too—before you pay, not after.

Plastic recycling: crusher & granulator knives dull too fast?
Common on small recycling lines and trading stock: knives wear out in days, screens block, or the motor labors—usually steel, edge, or gap—not “operator error” only.
See how we handle this →Shredder stopped or chewing slowly—rotor knives & hooks
Metal in bales, cheap replacement hooks, or wrong hardness: the shredder runs but downstream washing or granulating pays the price.
See how we handle this →Wood chipper: chips too big, knife flies dull, counter knife gap wrong
Sawmills, biomass yards, and small wood plants: chipper knife and counter knife/anvil pairing is ordinary maintenance—but wrong bolts or thickness stops production.
