In today’s competitive sheet metal industry, manufacturers require equipment that delivers both high productivity and exceptional accuracy. A Combination Slitting and Cut to Length Line integrates coil slitting and sheet cutting into one intelligent production system, allowing steel service centers and metal fabricators to process coils faster while maintaining outstanding dimensional precision.
Designed for galvanized steel, stainless steel, aluminum, and carbon steel, this fully automated production line reduces handling time, minimizes material waste, and improves production efficiency. Whether producing narrow strips or precision-cut sheets, the combination line provides a flexible solution for a wide range of industries.
Why Choose a Combination Slitting and Cut to Length Line?
Traditional slitting lines and cut-to-length lines often require separate equipment, additional labor, and repeated material handling. By combining both functions into one production line, manufacturers benefit from a streamlined workflow that significantly increases operational efficiency.
The integrated system performs coil loading, leveling, slitting, hydraulic shearing, fixed-length cutting, conveying, and stacking automatically. Intelligent PLC control ensures accurate synchronization throughout the entire production process, helping manufacturers achieve consistent product quality while lowering operating costs.
This production line is especially suitable for service centers processing multiple coil specifications every day.
Wide Material Compatibility for Various Industries
The line is engineered to process different metal materials while maintaining excellent cutting quality and dimensional consistency.
Suitable materials include:
- Galvanized Steel (0.5–1.5 mm)
- Stainless Steel (0.8 mm)
- Cold Rolled Steel
- Aluminum Coil
- Pre-painted Steel (PPGI)
Maximum processing width reaches 1250 mm, making the equipment suitable for both standard and customized production requirements.
Advantages of the Combination Slitting & Cut to Length Line
Compared with conventional production equipment, this integrated solution offers several significant advantages:
- Higher production efficiency through combined slitting and CTL operations
- Reduced material handling and labor costs
- Excellent strip width and sheet length accuracy
- Stable operation with intelligent automation
These advantages make the machine an ideal investment for manufacturers seeking to improve production capacity while maintaining consistent product quality.
Typical Applications
The finished strips and sheets are widely used in:
- Automotive manufacturing
- Construction materials
- Electrical cabinets
- Home appliances
- HVAC systems
- Metal furniture
- Roofing and wall panel production
- Industrial fabrication
Main Components of the Combination Slitting & CTL Line
1. Hydraulic Decoiler with Loading Car
The production line begins with a 5 Ton hydraulic decoiler equipped with an automatic loading car for safe and efficient coil handling.
Key features include:
- Hydraulic expansion system
- Pneumatic braking
- Automatic speed synchronization
- Remote operation
- Hydraulic lifting loading car
- Stable coil positioning
The decoiler accommodates coils with an inner diameter of 450–550 mm and widths up to 1500 mm, ensuring reliable feeding during continuous production.
2. Precision Leveling, Slitting and Hydraulic Cutting Unit
After decoiling, the material enters the high-precision leveling section, where multiple leveling rollers eliminate coil stress and improve sheet flatness before slitting.
The machine features:
- 4-HI precision leveling system
- 15 leveling rollers
- Motorized roller gap adjustment
- Four sets of slitting blades
- Hydraulic flying shear
- PLC-controlled cutting length
The slitting section provides clean edges with minimal burrs while maintaining excellent strip width consistency.
Production speed can be adjusted between 0–15 m/min according to material thickness and production requirements.
3. Intelligent PLC Control System
The entire production line operates through an advanced automation system that minimizes manual intervention.
Major electrical components include:
| Component | Brand |
|---|---|
| PLC | Delta |
| Touch Screen | Delta |
| Encoder | Omron |
| Frequency Inverter | Delta |
| Electrical Components | Schneider |
The control system allows operators to easily set:
- Sheet length
- Production quantity
- Working speed
- Automatic counting
- Remote operation
- Fault diagnosis
This intelligent interface greatly improves production efficiency while reducing operator workload.
4. Stable Hydraulic Power System
A reliable hydraulic station provides sufficient power for decoiling, cutting, and lifting operations.
Main features include:
- 5.5 kW hydraulic power
- Air-cooled hydraulic system
- Stable pressure output
- Low maintenance requirements
- Long service life
The optimized hydraulic design ensures smooth machine operation during long production cycles.
5. Automatic Conveyor and Finished Sheet Handling
After cutting, finished sheets are automatically transported by the conveyor system to the stacking area.
Benefits include:
- Smooth material transfer
- Reduced surface scratches
- Continuous production
- Improved production safety
- Reduced labor intensity
