Explore Line DetailsPositioned at the crossroads of Pan-European Corridor X and the Danube commercial waterway, Serbia has rapidly evolved into Southeast Europe’s powerhouse for automotive parts, agricultural machinery, railway infrastructure, and metallurgical processing.
The metallurgical sector anchored around Smederevo, coupled with the thriving automotive manufacturing supply chain in Kragujevac, Šumadija, and the Vojvodina industrial corridor, creates a dual-edge challenge for local steel service centers. Processors handle both domestic hot-rolled carbon coils and imported high-spec cold-rolled galvanized and stainless steel grades. Traditional start-stop cut-to-length (CTL) lines create severe bottlenecks: cycle pauses leave roller friction indentations, decelerate production lines down to 25–40 m/min, and introduce dynamic sheet buckle.
Wuxi Jianfa Machine-Building engineers flying shear production lines specifically to resolve this industrial friction. By synchronizing the cutting mechanism dynamically with the linear velocity of the strip, shearing occurs while material travels continuously at up to 80 to 120 m/min. This guarantees flawless surface preservation for automotive skin panels, white goods casings, and high-tensile structural components used in Serbia's national infrastructure upgrade projects.
Unlike conventional hydraulic guillotine cutters that mandate strip stoppage, our flying shear lines utilize mechanical rotary crank or eccentric servo-driven carriages to synchronize knife velocity precisely with strip transit.
The shear head is mounted on a rigid, cast-steel sliding bed driven by high-torque Siemens/Yaskawa brushless servomotors. During the cut cycle, the carriage accelerates to match strip speed within milliseconds, performs the scissor cut, and reverses back to home position with regenerative braking.
Equipped with interchangeable cassette assemblies featuring 19 to 23 micro-alloyed, induction-hardened (HRC 60-62) leveling rolls. Independent hydraulic wedge adjustments neutralize edge wave, center buckle, and coil set across both thick structural and delicate sheet metals.
Powered by industrial EtherCAT fieldbus networking with sub-microsecond synchronization. The line continuously cross-references uncoiler back-tension, leveler intermesh, loop depth, and high-resolution rotary encoders, compensating dynamically for strip thickness variance.

Our senior mechanical engineering team will calculate your required motor power, roll diameters, and carriage acceleration curves based on your exact coil tensile strength and target output tonnage.
From our 40,000 square meter modernized manufacturing complex in Wuxi, Jiangsu, Wuxi Jianfa combines four decades of metallurgical machinery innovation with full in-house machining and assembly control.
Unlike commercial trading intermediaries that broker machinery from fragmented workshops, Wuxi Jianfa oversees every micron of precision under our own roof. Our facility is equipped with heavy CNC floor-type boring and milling centers, high-capacity gantry machining beds, precision surface grinding equipment, and specialized heat treatment furnaces.
For Serbian industrialists, this vertical integration delivers two decisive advantages: uncompromising metallurgical integrity and resilient supply predictability. Critical mechanical elements—such as leveler rolls made from 60CrMoV, forged crank shafts, and bronze alloy sliding guideways—undergo ultrasonic flaw detection, deep cryogenic stabilization, and dynamic balancing prior to factory pre-assembly.
Located in Wuxi, Jiangsu Province, our plant is centered within China’s premier metallurgical machinery industrial cluster. This proximity gives us immediate access to world-class heavy foundries, high-precision bearing manufacturers, and leading automation component ecosystems.
Furthermore, our factory is situated within a 2-hour logistics transit window to Shanghai's international deep-water container and breakbulk terminals. Equipment destined for Serbia is securely ocean-freighted directly to Adriatic gateway ports (such as Bar in Montenegro or Rijeka in Croatia) or Greek hubs (Thessaloniki and Piraeus), followed by efficient rail or overland transport into the Serbian heartland.
We eliminate international procurement risks through complete adherence to Serbian standards (SRPS) and European Union Machinery Directives, backed by comprehensive lifecycle support.
All electrical switchgear and safety interlocks strictly comply with EN 60204-1, while mechanical safety conforms to ISO 12100 and EU Machinery Directive 2006/42/EC. Systems feature safety light curtains, dual-channel emergency circuits, and interlocked physical guarding designed for Serbian factory labor safety certifications.
Our senior deployment team—comprising experienced mechanical, hydraulic, and electrical commissioning engineers—travels directly to your facility in Serbia. We oversee foundational anchoring, precision laser alignment, hydraulic flushing, trial coil runs, and structured bilingual training for local operating personnel.
Equipped with high-security VPN edge gateways, our software engineers in Wuxi can diagnose PLC logic, tune servo drive loops, and analyze kinematic sensor telemetry in real-time. Critical wear consumables—including shear knives, leveler roll bearings, and hydraulic seals—are stocked with express courier dispatch.
Investing in a production line is a 15- to 20-year operational commitment. Our research and development focuses on autonomous intelligence, energy recuperation, and zero-defect quality control.
Integrating in-line high-resolution line-scan camera vision systems above the inspection table. AI computer vision models automatically detect pinholes, scratches, scale inclusions, and roll indentations at 100 m/min, flagging defective sheets before automatic sorting.
The cyclic acceleration and deceleration of the heavy flying shear carriage produces substantial kinetic energy. Our next-generation DC-bus servo power distribution captures this braking energy, re-routing it directly into the leveling drive to slash kWh consumption.
Reducing job-setup downtime through motorized hydraulic quick-clamping cassettes and robotic tooling arbors. Changing between heavy-gauge carbon steel leveling and thin-gauge aluminum processing can now be completed in under 15 minutes via HMI recipe selection.
In-depth answers addressing procurement hurdles, logistics routes, electrical compatibility, and mechanical engineering guarantees for projects in Serbia.
The decisive advantage lies in continuous strip motion and high throughput. In a conventional stop-start CTL line, the strip must come to a dead stop for every single shear cut, limiting line speeds to approximately 30-40 m/min and frequently creating pressure indentations on the sheet surface. In Jianfa's flying shear line, the cutting carriage accelerates to match strip velocity, cuts on the fly, and returns seamlessly. This elevates speed to 80-120 m/min, prevents surface damage on delicate materials, and nearly triples daily tonnage output.
Yes. We configure dedicated heavy-duty 4-Hi and 6-Hi levelers with rolls manufactured from high-alloy forged 60CrMoV or 9Cr2Mo steel, induction-hardened to HRC 60–62 and hard chrome plated. Our levelers feature reinforced backup roll assemblies and motorized hydraulic intermesh adjustments designed specifically to yield and plasticize high-strength steels up to 700–950 MPa (such as S700MC, QSTE700, or heavy S355JR plate) up to 16mm thickness.
Our electrical cabinets and motor drives are custom-engineered for Serbia’s standard electrical infrastructure: 400V 3-phase, 50Hz. We utilize globally recognizable brand components—such as Siemens S7-1500 PLCs, Siemens Sinamics or Yaskawa servo drives, Schneider contactors, and Rexroth hydraulics. This guarantees that your local plant maintenance electricians can readily troubleshoot systems and source standard off-the-shelf spares locally within Serbia.
Machinery sections are professionally preserved with anti-corrosion VCI barrier film, heavy desiccants, and seaworthy wooden/steel cradles. Freight is loaded directly from our Wuxi factory via Shanghai Port, shipped to Adriatic or Aegean deepwater ports (Bar, Rijeka, Koper, or Thessaloniki), and transported via bonded road convoys or rail directly to your customs terminal in Belgrade, Novi Sad, or Niš. We provide full commercial, phytosanitary, and origin documentation to streamline Serbian customs clearance under bilateral trade agreements.
Prior to shipping, your team is invited to our 40,000m² Wuxi headquarters for factory acceptance testing (FAT).
