Automatic Coil Slitting Line CSL-1250A — Light Gauge Metal Longitudinal Cutter for High-Speed Coil Processing
Why Choose the CSL-1250A Automatic Coil Slitting Line?
An automatic coil slitting line is the productivity powerhouse for steel coil service centers, ERW pipe manufacturers, structural stamping plants, and HVAC hardware producers that need to convert wide master coils into precise narrow strips with exceptional dimensional accuracy .
The Wadjay CSL-1250A light gauge metal longitudinal cutter is purpose-built for exactly that. It delivers 40 m/min line speed processing 1250mm wide, 0.3-2.0mm thick coils, with a heavy-duty 8,500kg frame and 22-30kW high-torque motor . The machine is engineered with three highly efficient features to maximize production:
- High-Precision Dual Arbor Head — rigid tool steel slitting shafts prevent chatter marks during continuous high-speed strip cutting
- Dynamic Tensioning Setup — multi-stage tension pads ensure tight, uniform recoiling across all slit steel strips
- Automated Edge Scrap Collection — dual side rewinders pack edge trimmings cleanly in real time

How the CSL-1250A Slitting Line Works
The Wadjay automatic coil slitting line executes a fully synchronized continuous production cycle :
- Continuous Uncoiling & Guiding — smooth hydraulic expansion mandrel eliminates coil slipping or surface scratches, feeding the master coil into the line
- Precision Longitudinal Slitting — the high-precision dual arbor head with rigid tool steel shafts executes multi-strip parallel cutting, preventing chatter marks during high-speed operation
- Automated Edge Scrap Collection — dual side rewinders pack edge trimmings cleanly in real time, maintaining a tidy production environment
- Dynamic Tensioning — multi-stage tension pads ensure tight, uniform recoiling across all slit steel strips
- Smart PLC Batch Control — digital touchscreen platform allows precise feed length measurement, automatic stop triggers, and production batch tracking
The entire process is orchestrated by the smart PLC control system, allowing operators to manage production with minimal training.

Application Scenarios
The CSL-1250A automatic coil slitting line serves a wide spectrum of metal processing industries :
- 🏭 Steel coil service centers — converting wide master coils into custom-width narrow strips for inventory diversification and just-in-time delivery
- ⚙️ ERW pipe manufacturing — rapidly converting wide raw coils into exact band widths needed for high-frequency resistance welding pipe production
- 🏗️ Structural stamping plants — high-volume narrow strip preparation for progressive dies and transfer presses
- ⚡ Transformer silicon steel processing — precision slitting of electrical steel for transformer windings
- 🏠 Roofing strip preparation — standing seam roofing, flashing, and fascia trims
- 🌬️ HVAC duct blanking — precise strip preparation for rectangular and spiral duct manufacturing
The machine’s ability to process 0.3-2.0mm thickness range at 1250mm width makes it exceptionally versatile — one line serves mixed-material workshops without retooling .

Why Wadjay’s CSL-1250A Stands Out
- True light gauge specialist — optimized for 0.3-2.0mm thickness range, the sweet spot for steel service centers and HVAC/R applications
- Chatter-free dual arbor head — rigid tool steel slitting shafts prevent chatter marks during continuous high-speed cutting
- Uniform recoiling guaranteed — dynamic multi-stage tension pads ensure tight, even coil winding across all slit strips
- Clean production environment — dual side automatic rewinders collect edge scrap in real time
- Smart PLC automation — digital touchscreen with precise feed length measurement and automatic stop triggers
- Heavy-duty 8,500kg frame — provides the mass needed for vibration-free 40 m/min operation
- High-torque 22-30kW motor — maintains consistent torque from thin copper foil to galvanized sheet steel
- 10-ton coil capacity — continuous hydraulic expansion mandrel handles heavy master coils without slipping
- Global voltage ready — 220V/380V/440V three-phase standard, customizable to local grid requirements
- Modular options — hydraulic coil loading car, extra high-carbon slitting knives & rubber rings, custom electrical transformers
Frequently Asked Questions
Q1: What coil widths and thicknesses can the CSL-1250A process?
A: The machine handles 1250mm width and 0.3-2.0mm thickness, suitable for carbon steel, galvanized steel, cold-rolled steel, and color-coated steel coils . For reference, industry-standard light gauge slitting lines in this range typically process cold-rolled steel, galvanized, color-coated, and stainless steel coils .
Q2: How fast is the slitting line?
A: Line speed is 0-40 m/min, controlled by a 22-30kW high-torque motor . The high-precision dual arbor head with rigid tool steel shafts prevents chatter marks even at maximum speed .
Q3: How much coil weight can the decoiler handle?
A: The continuous hydraulic expansion mandrel handles master coils up to 10 tons smoothly without coil slipping or surface scratches . For reference, industry light gauge lines typically permit 10-15 ton coils , and heavy-duty 1250mm lines reach up to 15 tons .
Q4: How many strips can be produced simultaneously?
A: The dual arbor head uses high-carbon tool steel rotary blades for multi-strip parallel cutting. As a reference, comparable 1250mm light gauge lines produce up to 10 strips (1-2mm thickness range) . Contact our engineering team with your specific strip width requirements for a customized configuration.
Q5: How uniform is the recoiling?
A: The dynamic tensioning setup with multi-stage tension pads ensures tight, uniform recoiling across all slit steel strips — eliminating loose winding and edge bow deformation .
