Tel.: +86-13855519988Designed specifically for deburring and trimming operations in tire manufacturing and rubber processing industries, suitable for post‑cure tread finishing, vent hole trimming, and flash removal on various tire types. Manufactured from tungsten carbide (cemented carbide), high‑speed steel, and high‑quality alloy tool steels, the blades offer extremely high hardness, wear resistance, and heat resistance, effectively resisting abrasive wear caused by rubber compounds and textile reinforcing materials. Widely used in automatic trimming systems on tire production lines and rubber product processing equipment, compatible with mainstream trimming machines such as Spadone, Pelmar, and Akarmak. The blades ensure smooth, burr‑free cuts, significantly improving the surface quality and production efficiency of finished tires.

Product overview
This product is an ultra-hard carbide tool for trimming vent spews and flashes from cured tires, ensuring clean, neat surfaces. Used in automated trimming stations for tire manufacturing and retreading, it guarantees consistent finished appearance.
Specialized edge optimization for rubber cutting
Based on the elasticity and friction characteristics of vulcanized rubber, these knives incorporate larger negative rake angles with specific edge land widths to achieve effective shearing and tearing action while minimizing frictional heat generation that could cause scorching or sticking.
High-strength impact-resistant body
To withstand impacts from tread blocks, bead wire edges, and cord layer splices during trimming, these knives are manufactured from high-toughness powder metallurgy high-speed steels or composite structures combining cemented carbide with steel substrates.
Precise trimming and dimensional control
Precision-ground locating surfaces ensure accurate trimming allowances with uniform stock removal, maintaining critical dimensions including overall circumference, tread width, and bead seat diameter within required process tolerances.
Self-sharpening design with edge durability
Through micro-chipping mechanisms during repeated use, these knives achieve a degree of self-sharpening that maintains effective cutting capability over extended periods, reducing auxiliary time for frequent resharpening.
Multiple blade formats with customization support
Manual trimming blades, power trimming blades, and CNC trimming blades are available to cover equipment with varying automation levels, with custom profile dimensions and edge parameters offered for tire sizes ranging from 12-inch to giant OTR sizes.

FAQ:
Q1: What are the main materials used for tire trimming blades?
A: The main materials are tungsten carbide (cemented carbide) and high‑speed steel (M2/SKH‑51). Tungsten carbide offers extremely high hardness (HRA 90‑94) and far better wear resistance than steel blades, making it ideal for high‑volume automated production. High‑speed steel (HRC 58‑64) provides a cost‑effective solution for medium production volumes or budget‑sensitive applications.
Q2: What types of tires are these blades suitable for?
A: They are suitable for all types of tires, including passenger car tires, truck tires, and off‑the‑road (OTR) tires, as well as those with textile reinforcing layers or steel belts, all of which can be effectively trimmed.
Q3: How do I choose the right hardness for a tire trimming blade?
A: For heavy‑duty tires with steel belts, we recommend tungsten carbide (HRA ≥ 90) for maximum resistance to abrasive wear. For standard rubber tires, high‑speed steel (HRC 58‑62) is sufficient. We can provide precise recommendations based on your specific tire type.
Q4: How can I extend the service life of tire trimming blades?
A: Regularly clean rubber build‑up from the blade surface to prevent adhesion; apply suitable coatings (e.g., TiN, TiAlN) to significantly improve wear resistance; and sharpen blades promptly when wear is detected to avoid edge chipping.
Q5: Which trimming machine brands are compatible with these blades?
A: They are compatible with major tire trimming machines such as Spadone, Pelmar, and Akarmak, and we can also customize mounting dimensions and blade structures to fit your specific equipment model.
