Famous Rotary Blade Manufacturer & Supplier

We manufacture complete, turnkey coil processing lines: high-precision slitting lines (rotary shear lines), cut to length (CTL) lines, synchronized flying shear production lines, 4-high and 6-high leveling machines, heavy-plate straightening machines, and continuous hot-dip galvanizing production lines. Equipment is available as monolithic, integrated turn-key installations or as targeted modular machine retrofits to boost existing line throughput.

Our processing lines are calibrated to handle hot-rolled carbon steel, cold-rolled automotive steel, electrolytic and hot-dipped galvanized sheets, 200/300/400-series stainless steels, silicon electrical steel, and aerospace-grade aluminum alloys. We engineer specific hydraulic hold-downs and knife steels around tensile ratings from soft temper brass up to 1500 MPa Advanced High-Strength Steels (AHSS).

Minimizing edge burr relies on three fundamental engineering parameters: arbor deflection rigidity, precise radial run-out under load (≤0.002mm), and exact horizontal knife clearance (typically set at 7-10% of strip gauge). Our rotary knives are forged from premium tool steels (SKD-11, D2, H13K, or PM-HIP steels), double-tempered, and cryogenically treated to maintain RA ≤ 0.2μm surface roughness and avoid micro-spalling.

To generate an optimized turnkey layout and mechanical quotation, please supply: material grade & yield strength (MPa), coil thickness (min/max mm), entry coil width (mm), max coil entry and exit weights (tonnes), inner/outer diameter requirements, minimum slit width, maximum number of cuts per thickness, target line velocity (m/min), and facility power grid parameters (voltage, frequency, compressed air/water cooling specs).

Yes. We dispatch dedicated field service engineers with specialized mechanical, hydraulic, and electrical proficiencies across North America, Latin America, Europe, the Middle East, Africa, and Southeast Asia. We oversee civil foundation alignment, mechanical assembly, cold run-ins, strip threading, knife shimming training, PLC parameter configuration, and continuous trial-production signoffs.

Absolutely. We strongly advocate full Factory Acceptance Testing at our 40,000m² manufacturing complex in Wuxi, Jiangsu. Clients or third-party inspection agencies (SGS, TÜV, Bureau Veritas) can directly verify dimensional tolerance, safety interlocking, dynamic uncoiler braking, hydraulic clamping, and dry runs prior to containerization and sea shipment via Shanghai Port.
