Circular slitter blades built to your spec

Our custom circular slitter blades are made to your exact outside diameter, bore, thickness, and bevel. Whether you run flexible film, aluminium foil, paper, or light-gauge metal, we match the edge geometry your line needs — and we can reverse engineer the blade from your worn sample if the drawing is gone.

Materials we cut from

• D2 / SKD11 — high-wear tool steel for long slitting runs.
• HSS — heat-resistant edges for higher surface speeds.
• Stainless — food- and pharma-grade lines.
• Solid carbide — maximum edge life on abrasive webs.

Why buyers switch their slitter blades to HIBO

Free sample (you cover freight), a 24-hour quote, and a 30-day production lead — versus the 35–45 days most overseas suppliers quote. For converting and packaging lines that can’t afford downtime, a proven sample beats a gamble on 100 blades.

Typical applications

Plastic film and foil slitting, paper and label converting, nonwoven and textile slitting, and thin metal strip. If your line runs rotary slitting, we supply the industrial cutting blade for it.

What the geometry has to get right

A slitter pair cuts by shear, not by pressure. The two edges pass each other with a clearance that has to suit the material thickness — too tight and the edges rub and load the machine, too loose and the web is torn rather than cut. Clearance is a property of the pair, so both knives have to be made and set together.

Concentricity matters as much as the edge. A knife that runs out of true finishes the web unevenly and wears one side of the edge first, which is often mistaken for a material problem.

Where a slitter blade fails

• Burr or dust on one side of the slit. Clearance, or a mismatch between the pair.
• Uneven wear around the circumference. Run-out — check mounting and shaft before the blade.
• Web wandering between slits. Tension, or a dull edge crushing rather than shearing.
• Edge chipping. Impact from contamination, or an edge too hard for the application.

How we match an existing slitter

Send the worn knives. We measure diameter, bore, thickness and edge angle, then confirm the pair as a set. Tell us the material and its thickness — clearance is the first thing we need to agree on.

Slitter blade questions

Do the top and bottom knives have to be replaced together?

Ideally yes. They wear against each other and the clearance is set between them; replacing one half alone usually shifts cut quality.

Can you match a knife from a sample cut?

The cut tells us about quality, not dimensions. Send the knife — we measure it and send the drawing back for confirmation.
