Learn MoreGlobal Industrial Landscape: The Rise of Flying Shear Technology
How dynamic flying shear mechanisms are transforming modern coil processing centers across North America, Europe, Asia, and emerging industrial hubs.
Throughput Optimization
Traditional stop-and-go cut-to-length lines suffer from constant acceleration and deceleration losses. Modern flying shears accelerate the cutting head to match the strip velocity perfectly, allowing continuous non-stop sheet cutting at speeds exceeding 80 to 120 m/min.
Surface Quality Integrity
Stopping a metal strip for static shearing often introduces roll marks, slip scratches, and mechanical stress marks. Flying shears eliminate intermittent slippage, making them essential for delicate surfaces like auto-grade sheets, bright stainless, and coated aluminum alloys.
Servo Synchronization
Equipped with closed-loop multi-axis servo drives and real-time optical encoders, modern flying shear cutters achieve length tolerances tighter than ±0.5mm, drastically minimizing secondary sizing operations and maximizing raw material utilization.

Global Enterprise Procurement Specification Guide
Essential engineering data points required by Wuxi Jianfa engineers to develop a precise, optimized technical and commercial proposal.
1. Material Metallurgical Specs
Indicate yield strength (σs in MPa), tensile strength (σb), and coil material type (hot-rolled, cold-rolled, galvanized, stainless grades 304/316, or aluminum). Higher yield steels demand elevated leveling drive power and reinforced shear frames.
2. Coil Dimensions & Weight Limits
Specify minimum and maximum material thickness, coil strip width, maximum outer coil diameter (OD), inner mandrel diameter (ID), and total coil payload (e.g., 15t, 25t, 35t) to dimension the uncoiler mandrel and coil car.
3. Output Tolerances & Stacking
Define desired cut length window (e.g., 500mm to 6,000mm), permissible length tolerance (±0.5mm), diagonal squareness tolerance, surface protection requirements (PVC filming or interleaving), and stack discharge style.
Frequently Asked Questions (FAQ) & Technical Clarifications
Direct technical answers from Wuxi Jianfa's chief metallurgical machinery engineering team.
What equipment does Wuxi Jianfa specialize in?
We manufacture full coil processing lines: high-speed flying shear lines, standard cut to length lines, rotary slitting lines, precision plate leveling machines, sheet straightening machines, and continuous coil galvanizing production lines.
Which material grades can your flying shear cut?
Our lines handle hot-rolled, cold-rolled, galvanized, stainless steel, and aluminum coils, ranging from light gauge 0.3mm sheets up to 16mm or 25mm structural steel, including high-strength grades up to 900 MPa yield.
How does a flying shear outperform a conventional cut-to-length line?
A conventional CTL line stops the entire metal strip at every cut, inducing mechanical stress, motor heat, and reduced throughput. A flying shear synchronizes its cutting carriage to match strip speed, achieving continuous shearing with zero stopping marks.
What length accuracy and diagonal tolerances are achievable?
Using ultra-responsive digital servos and high-resolution rotary encoders, our flying shear lines deliver cutting length accuracy within ±0.3mm to ±0.5mm and diagonal squareness within ±0.5mm across sheet lengths up to 4 meters.
Do you support on-site overseas installation and commissioning?
Yes. Our factory dispatch engineers manage foundation inspection, mechanical alignment, electrical integration, and cold/hot commissioning on-site, alongside complete operator training and lifetime remote diagnostics.
Can international buyers inspect equipment prior to shipment?
Absolutely. We encourage client visits or independent third-party inspection (SGS, TUV, Bureau Veritas) at our 40,000 m² factory in Wuxi, Jiangsu—conveniently situated near Shanghai—for full FAT sign-off before crating.
