Zhongtuo Simple Cut To Length Line for Thin Sheet 25–35 m/min High Speed Coil Cutting Machine

A simple cut-to-length line for thin sheet is a highly efficient coil processing solution designed to convert metal coils into flat sheets with precise length control. With a working speed of 25–35 meters per minute, this line is widely used in construction, fabrication, HVAC, and light industrial manufacturing where stable output and clean cutting quality are essential.

Compared with traditional manual or semi-automatic cutting methods, this CTL system significantly improves productivity, reduces labor dependency, and ensures consistent sheet quality across every production batch.

1. Production Overview and Technical Capability

This cut to length line is optimized for thin sheet processing, typically handling galvanized steel, cold-rolled steel, aluminum, and stainless steel within a controlled thickness range.

It combines uncoiling, leveling, feeding, precise cutting, and automatic stacking into one continuous production flow, ensuring smooth operation and stable sheet output.

Key technical parameters:

The system is designed to maintain stable performance even under continuous high-speed operation.

2. Main Equipment Configuration

This production line consists of several coordinated units, each responsible for a key stage of processing. Together, they ensure precision, efficiency, and automation.

(1) Hydraulic Decoiler – 8 Ton Capacity

The decoiler supports and unwinds steel coils smoothly. Its hydraulic expansion system ensures stable coil holding, while the pressure arm prevents material loosening during feeding.

• Strong welded steel frame structure
• Hydraulic expansion: Ø470–630 mm range
• 5.5 kW drive system with gearbox transmission
• Supports up to 8 tons coil weight

(2) Leveling and Servo Feeding Unit

This unit ensures the sheet is completely flat before cutting, eliminating coil memory and deformation.

• 40Cr hardened rollers with HRC62 surface hardness
• Servo-controlled feeding for precise length accuracy
• Pneumatic release system for smooth material entry
• High-speed synchronization with cutting system

(3) Motorized Shearing System

The cutting section adopts an advanced mechanical shearing design that improves accuracy and reduces deformation.

• Flywheel and pneumatic clutch transmission
• Small shear angle for clean cutting edges
• Adjustable blade clearance for easy maintenance
• Suitable for both metal and non-metal sheets

(4) Conveyor Table and Automatic Stacker

After cutting, sheets are smoothly transported and neatly stacked for easy packaging and storage.

• Roller conveyor driven by hydraulic motor
• Adjustable stacking length and width control
• Pneumatic tapping system for alignment
• Stable carbon steel welded frame

3. Working Process Flow

The full production process of the line is continuous and highly automated:

Uncoiling → Leveling → Servo Feeding → Fixed-Length Cutting → Conveying → Automatic Stacking

This integrated workflow ensures that operators only need to monitor the system, greatly reducing manual labor while improving consistency.

4. Advantages of This Cut to Length Line

A modern thin sheet CTL line offers significant benefits for manufacturers aiming to improve productivity and reduce operating costs.

Main advantages:

First, high efficiency is achieved through continuous operation at 25–35 m/min, making it suitable for medium to large-scale production.

Second, precise cutting accuracy ensures every sheet meets required length tolerance with minimal deviation.

Third, reduced material waste is achieved through servo-controlled feeding and optimized leveling, improving raw material utilization.

Finally, stable and low-maintenance design ensures long-term industrial reliability, even under continuous operation.

5. Application Industries

This cut to length system is widely used across multiple industries due to its flexibility and stable output quality.

• Building and construction materials
• HVAC duct manufacturing
• Metal furniture production
• Automotive sheet processing
• Electrical cabinet fabrication

It is especially suitable for factories that require consistent sheet size production with high efficiency and low manpower dependency.

The simple cut to length line for thin sheet (25–35 m/min) is a reliable and efficient solution for modern coil processing. With its stable structure, precise servo control, and automatic stacking system, it delivers high-quality sheet output while significantly improving production efficiency.
