Our slitting blades and cutting knives are crafted with qualified wear-resistant materials, undergoing forging, heat treatment, and grinding processes. They boast higher accuracy, wear-resistance, oil-resistance, heat-resistance, and acid/alkali resistance, ensuring long-term use without deformation. Ideal for slitting thin or soft-surfaced materials, they guarantee precision.
We provide OEM and custom services based on technical drawings or samples. Our blades' processing accuracy includes:
- Surface roughness: ≤ 0.002mm
- Flatness and parallelism: ≤ 0.001mm
- Blades heat treatment hardness: tailored to blade material and cutting material thickness
Heat treatment methods involve vacuum deoxidation and salt bath furnace treatments. Available materials for circular blades and knives include SKH-9, SKD-11, LD, W6Mo5Cr4V2AL, H13K, M42, K30, ASP60 power alloy steel, and custom materials.
