Precision Aluminium Slitting Engineering: 40+ Years of Manufacturing Mastery
Aluminium slitting presents unique rheological challenges compared to ferrous steel: lower modulus of elasticity, severe galling tendencies, and critical surface finish vulnerability. Discover how Wuxi Jianfa redefines industrial slit processing.
Zero-Gall Arbors & Anti-Marking Rolls
Processing structural (6xxx) or aerospace-grade (7xxx) aluminum mandates tungsten carbide tooling, micro-mirror chrome arbors, and non-marking polyurethane contact surfaces that prevent friction transfers, oxide adhesion, and scratches.
Closed-Loop Differential Recoiling
Aluminium coils exhibit variable thickness profiles (crown tolerance). Jianfa's differential friction rewinding shafts and hydraulic tension belt systems eliminate uneven strip sag, preventing core slippage and telescope recoiling.

Get verified answers directly from our senior metallurgical machinery engineering team.
What coil processing equipment does Wuxi Jianfa manufacture?
We manufacture complete turnkey coil processing lines: high-speed slitting lines (rotary shear lines), cut to length (CTL) lines, high-throughput flying shear production lines, precision multi-roll leveling machines, plate straightening machines, and continuous coil processing and galvanizing lines. Equipment can be supplied as a complete greenfield plant or as modular stations to upgrade existing lines.
Which materials can your slitting and cut to length lines process?
Our machinery specializes in processing aluminum and aluminum alloys (1xxx, 3xxx, 5xxx, 6xxx, and 7xxx series), hot-rolled steel, cold-rolled carbon steel, galvanized coil, high-strength structural steels (up to 1200 MPa yield strength), silicon electrical steel, and stainless steel (200, 300, and 400 series) with zero surface marking.
How do I choose between a slitting line, a CTL line, and a flying shear line?
Choose a Slitting Line when your objective is transforming master coils into narrow recoiled strips for tube mills, roll forming, or progressive die stamping. Choose a Cut to Length (CTL) Line for generating dead-flat, neatly stacked rectangular plates or sheets. Choose a Flying Shear Line when high-speed continuous sheet throughput is demanded, as the rotary or flying shear synchronizes with moving strip up to 80–120 cuts/min without stopping strip feed.
How does an aluminium slitter prevent scratching and surface defects?
Aluminium is susceptible to galling. Jianfa lines utilize precision ground, hardened alloy or tungsten carbide slitter knives, mirror-polished arbors, polyurethane-coated pinch rolls, non-marking felt or belt-tension bridles, and specialized oil-mist lubrication systems that prevent adhesive aluminum pickup on tool edges.
What technical data is required to obtain an accurate technical proposal?
Key information needed includes: coil material grade and tensile/yield strength, master coil thickness range, master coil maximum width, maximum coil weight, inner and outer coil diameters (ID/OD), target line operating speed, minimum cut width, maximum number of cuts per pass, edge burr limits, and local factory plant power voltage/frequency (e.g., 400V 50Hz / 480V 60Hz).
Do you support overseas installation, commissioning, and factory audits?
Yes. Our dedicated field service engineers handle on-site mechanical alignment, electrical commissioning, and operator qualification globally.
