In Binh Duong, Dong Nai, and Long An, coil processing centers support massive civil infrastructure, pre-engineered steel buildings (PEB), and container manufacturing. Local steel fabricators face surging labor costs and aggressive production deadlines. Upgrading to a continuous rotary flying shear line expands line output from 25 sheets/min to over 85 sheets/min, effectively tripling processing volume per shift without increasing factory floor footprint.
Global Export Compliance & EV Mandates
With Vietnam's participation in CPTPP and EVFTA, exported metal enclosures, air conditioning ducts, and automotive press blanks face rigorous international quality standards. The integration of high-resolution digital servo positioning, dynamic roll-leveler cassette changes, and CE Machinery Directive (2006/42/EC) compliance ensures that Vietnamese enterprises operate with verifiable European safety, acoustic control, and dimensional precision.
Engineering Superiority: Flying Shear Architecture vs. Stop-and-Go Lines
Why modern Vietnamese processors are actively decommissioning stop-and-go stationary shearing lines in favor of dynamic rotary and reciprocating servo tracking shears.
| Performance Parameters | Traditional Stop-and-Go CTL Line | Reciprocating Moving Shear (Pneumatic) | Advanced Servo Rotary Flying Shear (Jianfa) |
|---|---|---|---|
| Strip Feed Behavior | Intermittent start-stop cycle every cut | Continuous feed with synchronized carriage | Continuous high-velocity feed without deceleration |
| Line Cutting Speed | 20 – 35 m/min max output | 40 – 60 m/min | Up to 80 – 100 m/min sustained velocity |
| Surface Protection | Risk of roller pinch marks during sudden halts | Minor risk on sensitive mirror/prepainted finishes | Zero stop-mark; pristine handling for 2B, BA, & prepainted |
| Length Tolerance (at 2m) | ±0.8 to 1.2 mm | ±0.5 mm | ±0.2 to 0.3 mm (high-speed rotary encoder) |
| Kinetic Wear & Motor Stress | Extreme inertia spikes on clutch & hydraulic valves | Moderate carriage acceleration load | Balanced rotational kinematics, low energy consumption |
| Downstream Stacking Efficiency | Batch conveyor pauses, manual or semi-auto | Air-float / drop stacker | Magnetic / vacuum high-speed stacker with auto-pallet change |
The Kinematic Synchronization Mechanism
At the heart of the Jianfa Flying Shear line is an advanced multi-axis motion controller utilizing an EtherCAT high-speed industrial fieldbus. A master encoder continuously calculates the linear speed of the steel strip emerging from the multi-roll precision leveler. The secondary rotary servo drives accelerate the dual-drum cutting blades so that at the precise moment of engagement, the tangential speed of the knife edges matches the strip linear velocity to within 0.05% tolerance. This eliminates material bunching, edge burrs, and mechanical blade chipping.
Dynamic Roll Leveling with Automated Crown Compensation
Cutting high-strength steel (yield strengths exceeding 550 MPa to 780 MPa) presents extreme residual stress. Jianfa integrates a 6-high (6-Hi) or 4-high (4-Hi) cassette-type leveler with intermediate backup rolls. Hydraulic micro-wedges provide localized roll deflection adjustments to cancel edge wave, center buckle, and camber. The leveled sheet remains perfectly flat even after deep-draw automotive pressing or laser cutting across Vietnamese fabrication floors.
CE Certification Rigor & Vietnam Localized Safety Integration
Comprehensive European conformity combined with full compliance with Vietnam Ministry of Industry and Trade (MOIT) technical regulations.
Machinery Directive 2006/42/EC
Every flying shear line produced by Jianfa is manufactured in strict conformity with EN ISO 12100 risk assessment methodologies. All rotating pinch rolls, uncoiler arms, and flying shear cutting envelopes are fully protected by interlocking optical light curtains, trapped-key interlocks, and emergency stop circuits rated to ISO 13849-1 Performance Level d/e (Cat 4).
Low Voltage & EMC Directives
Compliant with EN 60204-1 (Safety of machinery - Electrical equipment of machines), our electrical enclosures feature IP54 protection, climate control units for tropical humidity, and complete galvanic isolation against industrial surges. High-performance EMC line filters prevent electromagnetic harmonics from perturbing sensitive CNC devices across the client's plant.

Next-Generation Trends Shaping the Flying Shear Industry
How intelligent sensor telemetry, automated blade clearance adjustment, and Industry 4.0 IoT are revolutionizing coil processing efficiency.
Self-Learning AI Blade Gap Tuning
When switching between 0.5 mm prepainted galvanized coil and 3.0 mm high-strength structural coil, traditional lines require manual feeler gauge calibration. Jianfa's newest smart flying shears incorporate motorized blade gap adjustment managed by the central PLC. The system queries material thickness and yield strength presets from barcode scans to position the upper and lower knife overlap with 0.01 mm servo resolution.
Predictive Vibration Telemetry
Equipped with industrial accelerometers on main bearings and planetary gearboxes, our systems continuously monitor vibration spectra and oil contamination. Potential mechanical issues—such as bearing spalling or gear tooth wear—are detected thousands of operating hours before failure occurs. Data is transmitted securely via VPN gateways, allowing our engineers in Wuxi to assist Vietnamese maintenance teams remotely.
Automated Palletization & AMR Integration
As manual packing stations struggle to match 100 m/min flying shear line speeds, our modern installations in Vietnam integrate automatic magnetic and suction stackers. Double-station lowering tables allow finished pallets to be ejected, weighed, strapped, and tagged via automated transfer cars while the shearing line continues running uninterrupted.

Frequently Asked Questions on Flying Shear Equipment in Vietnam
Direct answers from our senior chief mechanical engineers and cross-border installation directors.
Why is a flying shear line preferred over a conventional stop-and-go cut-to-length line?
In a traditional stop-and-go line, the continuous feed strip must be braked to a complete stop for every individual cut, requiring looping pits and causing mechanical shock, hydraulic heat buildup, and roller indentation marks on surface-sensitive coils. A flying shear line cuts continuously while the strip travels at full speed, tripling production volume while completely safeguarding material surface integrity.
What specific CE safety certifications do your flying shear machines maintain?
Our flying shear production lines strictly comply with European Union directives: Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. All electrical systems comply with EN 60204-1, and mechanical hazard zones are monitored by safety relays and light curtains compliant with EN ISO 13849-1 standards.
