- Winding on the mould
- Continuous equal-thickness technology compensates for parameters of small sizes and dimensions that are difficult to form with cold rolled blades
- High forming accuracy with essentially the same thickness for outer and inner edges
- High material utilization and forming efficiency
- Material options: Carbon steel, manganese steel, stainless steel
Thickness 2-5mm: Strip width ≤30mm
Thickness 6-10mm: Strip width ≤50mm
Thickness 10-20mm: Strip width ≤80mm
Manufactured using winding or segmented stamping processes, thickness deviation can be controlled within ±0.1mm, resulting in substantial improvement in mechanical properties. Maximum stress is reduced by more than 15% compared to traditional blades.
Made with 304 or 316L stainless steel, they offer outstanding corrosion resistance, with a service life three times that of carbon steel blades in chloride ion and acid/alkali environments. Surface roughness Ra≤0.8μm reduces fluid resistance by 20%, lowering conveying energy consumption.
These blades are suitable for various applications: small-sized wound blades for food processing machinery and agricultural harvesters (conveying efficiencies up to 20t/h); large-sized segmented stamped blades for heavy-duty conveying in mines and cement production lines. 40mm thick wear-resistant steel blades have a lifespan of over 8 years.
