Built for lines that can’t stop

Printing and converting demand clean, dust-free cuts. Our custom blades for paper and printing are made to your exact diameter, bore, and bevel. We can reverse engineer the blade from your worn sample when the drawing is gone.

Why buyers in Paper & Printing choose HIBO

• Free sample — a working blade on your machine before you commit to 100 pcs.
• 24-hour quote — from the day we receive your drawing.
• 30-day lead — vs. the 35–45 days peers quote.
• Reverse-engineer — send the worn blade, get the drawing and a sample.

Typical applications

Printing rewinders, slitter-rewinders, corrugated and carton trimming, and label converting.

What wears first on a paper line

Paper is more abrasive than most people expect. Coated stocks carry clay and calcium carbonate; recycled fibre carries grit that never fully washes out. The edge does not simply go dull — it rounds over and micro-chips at the same time, and the first symptom is usually dust at the trim rather than a visible defect in the sheet.

On coated and gloss grades a second failure mode appears: coating binder and resin build up on the bevel. The edge underneath may still be sound, but the build-up changes the effective cutting angle and the trim width starts to wander over a long run.

How a paper blade fails — and what it tells you

• Dust at the trim edge. The edge has rounded. Usually abrasive wear rather than impact — the blade is simply at the end of its life.
• A shiny band or step on the bevel. Contact is only happening on part of the edge. Check seating and alignment before blaming the blade steel.
• Chips along one section only. Something is hitting the edge — a splice, a staple, a foreign object in the reel. Localized damage is almost never a material problem.
• Trim width drifting during a run. Build-up on the bevel, or the blade is not seated square.

Blades we supply for paper and printing

We work from your drawing, so this is a starting point rather than a catalogue. If your machine uses something that is not listed, send the worn blade and we will match it.

• Slitter-rewinder top and bottom knives — shear-cut pairs, set to your reel width.
• Sheeter and guillotine blades — long straight edges for cut-size lines.
• Trim and deckle knives — the narrow blades that set the finished width.
• Corrugated and carton trimming blades — heavier sections for board.
• Perforating and serrated edges — to your tooth pitch and depth.

Paper and printing blades — common questions

Can you match a blade when I have no drawing?

Yes. Send the worn blade — even a broken one — and we measure diameter, bore, thickness, bevel angle and tooth form, then send the drawing back for you to confirm before anything is made.

How long should a slitter blade last?

It depends on stock, filler content, running speed and how the blade is set. Any number we quote without seeing your line would be a guess, so we do not quote one. What we do instead is make the sample, let you run it, and compare wear against what you are using now.

Do you supply matched top and bottom pairs?

Yes. Shear-cut slitting only works if the pair is made together — clearance is a property of the set, not of each blade on its own. We make and mark them as a set.
