Molds have small air holes during tire molding and heating.
After heating, rubber burrs form on tire sides and shoulders.
These burrs hurt appearance and performance.
Use sharp, precise edges to cleanly remove rubber leftovers.
Make the tire surface smooth and meet quality standards.
New tire production: Used on automated lines with robots or trimming machines for fast, mass trimming.
Tire retreading: Trim edges and seams after retreading to ensure quality.
High wear resistance
High sharpness
Long life
Circular blades: Most widely used. Small size, fits rotary trimmers. For fast, continuous cutting of large burr areas.
V‑shaped / irregular blades: Custom edges for precise trimming on patterns, corners, and hard‑to‑reach areas.
Straight blades: Flat cutting edge. For clean linear trimming on tire edges and seams.
Tungsten carbide / hard alloy:
Very hard and wear‑resistant
Much longer life than steel
Stays sharp longer, reduces blade changes
Best for large automated production
High‑speed steel (HSS):
Lower cost, easy to produce
Good for small‑batch or non‑continuous work
Needs regular sharpening to stay sharp
Accurate size: Inner diameter, outer diameter, and thickness must match your machine.
Smooth sharp edge: Mirror‑polished edge reduces rubber sticking and makes cleaner cuts.
Clean rubber residue off blades after use.
Use special lubricant regularly to reduce friction and sticking.
Dull or low‑quality blades can pull rubber and leave marks.
Our blades are designed for high precision.
We use high‑quality high‑carbon steel and special alloys.
Vacuum heat treatment makes blades HRC 58–62 hardness.
Blades stay sharp for thousands of cuts.
Optional low‑friction coating prevents rubber sticking.
Passenger car tires (PCR)
Truck and bus tires (TBR)
OTR tires
Clean, burr‑free surface
Longer blade life → less downtime
