Rubber & plastic blades built to your spec

Our custom rubber and plastic cutting blades are made to your exact profile, mounting, and edge geometry. Whether you dice rubber, cut profile, or trim extrusion, we match the blade your polymer 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 production runs.
• HSS — heat-resistant edges for higher surface speeds.
• Stainless — food- and pharma-grade lines.
• Solid carbide — maximum edge life on abrasive materials.

Why buyers switch their 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.

Typical applications

Rubber dicing and profile cutting, plastic extrusion trimming, gasket and seal cutting, and polymer sheet slitting. If your line cuts polymers, we supply the industrial cutting blade for it.

What the geometry has to get right

Rubber and soft polymers do not cut the way metal or paper does — they deform first and recover afterwards. The edge has to be keen enough to start the cut before the material stretches away from it, and the bevel has to be robust enough to survive the elastic snap-back at the end of the stroke.

On sheet and profile cutting the support underneath matters as much as the blade. Cutting into a soft backing lets the material flow instead of parting, and the cut edge shows it.

Where a rubber or plastic blade fails

• Cut edge torn rather than cut. Edge is dull, or the backing is too soft.
• Edge chipped on filled compound. Abrasive filler plus impact — toughness first.
• Material sticking to the blade face. Friction heat or surface finish.
• Blade bending in service. Section too thin for the load; the failure is mechanical, not metallurgical.

How we match an existing blade

Send the worn blade. We measure profile, edge angle and fixing pattern, then ask what the material is and whether it is filled — those two answers change the recommendation more than the drawing does.

Rubber and plastic blade questions

Harder or tougher for filled compound?

Look at the failure. Even wear across the edge means go harder; chips and impact marks mean go tougher.

Can you match a blade with no drawing?

Yes — that is the normal case. Send the worn part and we measure it, including any relief or undercut that a photograph would not show.
