China Flying Shear Production Line Supplier & Factory for the Luxembourg Market

Every production line designated for the European Union market is engineered strictly according to the European Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. Safety architectures adhere to EN ISO 13849-1 (PL e, Cat. 4) using dual-channel safety relays, physical interlocked light curtains (Sick or Pilz), perimeter perimeter fencing with safety switches, emergency pushbuttons on all operational nodes, and fail-safe PLC controllers (Siemens S7-1500F). All technical files, risk assessment documentation, and EC Declarations of Conformity are supplied in full English and French/German upon request for seamless sign-off by Luxembourg's Inspection du Travail et des Mines (ITM).

A reciprocating crank (toggle) flying shear operates on a linear carriage that accelerates forward to match strip velocity, actuates vertical guillotine blades, and reverses back to home position via linear servo ball screws or rack-pinion drives. This is ideal for heavier gauges (3.0mm – 12.0mm). In contrast, a continuous rotary shear employs twin counter-rotating drum shafts fitted with helical blades. The drums rotate continuously, dynamically adjusting rotational acceleration during each revolution so the blade tip speed matches the strip at the exact shear point. Rotary designs achieve astonishing line speeds (80 – 120 m/min) on light-to-medium gauges (0.3mm – 3.2mm), delivering the ultimate throughput for high-volume service centers.

Yes. Processing high-yield materials (σs ≥ 700–1000 MPa) requires substantial structural stiffness. Jianfa heavy-gauge levelers and flying shear housings are fabricated from ultrasonic-tested Q355B/Q690 structural steel plates, fully normalized through thermal stress-relief annealing furnaces, and precision CNC-bored in single setups. Leveler rolls are forged from premium alloy steel (42CrMo, 60CrMoV, or Cr12MoV), induction-hardened to HRC 60–62, and supported by multiple clusters of heavy-duty back-up rolls with hydraulic micro-deflection adjustment to eliminate crown deflection during high separating forces.

Wuxi Jianfa provides a complete turn-key commissioning model. We deploy an experienced engineering task force (senior mechanical engineer, lead electrical/software engineer, and master hydraulic technician) on-site to your facility in Luxembourg. We oversee mechanical anchoring, pipeline hydraulic interconnection, fieldbus cabling, cold I/O checks, and hot coil commissioning up to full production rate. In parallel, our engineers conduct structured hands-on training for your operators and maintenance staff. Furthermore, our machines include industrial VPN routers (eWon/Siemens Scalance) enabling 24/7 direct remote telemetry support from our Wuxi engineering headquarters.

Under standardized continuous production conditions at 80 m/min on a 2000mm sheet length, our flying shear lines achieve: Length Tolerance: ≤ ±0.20 mm (via high-resolution servo encoders or non-contact laser Doppler surface velocimeters); Diagonal Squareness Difference: ≤ ±0.35 mm (enforced by rigid side-guide pinch units and precision knife parallelism); Edge Burr Ratio: ≤ 5% of nominal sheet thickness (achieved through motorized knife clearance adjustments matched to steel tensile properties).

Our 40,000 m² factory in Meicun, Wuxi enjoys premier connectivity: just 120 km from the Port of Shanghai via direct expressway. Machinery modules are professionally sealed with vacuum anti-rust barrier foil, desiccants, and heavy seaworthy steel framing. Ocean transport routes run directly from Shanghai to Port of Antwerp or Port of Rotterdam (approx. 28–35 days transit), followed by specialized flat-bed truck or multimodal rail transit directly to Bettembourg or Esch-sur-Alzette, Luxembourg. Total lead time from contractual engineering freeze to delivery ranges between 120 and 180 calendar days depending on configuration complexity.

The primary wear parts consist of upper/lower shear blades (manufactured from tungsten-alloyed H13K, D2, or powder-metallurgical ASP-2023 steel), polyurethane pinch roll jackets, leveling roll bearings, and hydraulic filter elements. Each production line is supplied with an exhaustive "Two-Year Commissioning & Operation Spare Parts Kit." Because we design using standardized world-class components (SKF/NSK bearings, Rexroth valves, Schneider low-voltage components, Siemens drives), local replacements can easily be sourced within hours across Luxembourg and Germany. Bespoke blades are stocked at our central hub and dispatched via DHL/FedEx priority airfreight within 48 hours.

Yes. Many European steel processors wish to upgrade line productivity without the substantial expense of replacing uncoilers, levelers, and civil foundations. Jianfa provides complete modular retrofits. We can remove the old start-stop mechanical shear and looping pit, install our compact synchronous servo flying shear assembly along with an independent motion controller, and synchronize it with the existing line speed master encoder, immediately converting an antiquated 25 m/min line into an 80 m/min continuous powerhouse.
