In modern metal fabrication and steel service industries, the metal coil slitting machine plays a crucial role in converting wide steel coils into multiple narrower coils (strips) for downstream processes such as tube production, roll forming, and stamping.
Shijiazhuang Faith Machinery Co., Ltd., based in Hebei, China, is a professional manufacturer of metal coil slitting lines, offering customized solutions that meet high-speed and high-accuracy production demands.
With advanced engineering, intelligent control systems, and a focus on operational efficiency, Faith Machinery delivers durable and cost-effective coil slitting equipment for global customers.
A metal coil slitting machine, or coil slitting line, is designed to slit large metal coils into smaller strips of precise width. The machine uncoils the master coil, passes it through circular slitting knives, and then recoils the slit strips for easy handling and transport.
Unlike a cut to length line, which cuts the coil into sheets, the slitting line produces multiple coils of specific widths. This makes it ideal for manufacturers who need narrow strips for welding, forming, or assembly operations.
A standard metal slitting line includes several synchronized components working together to ensure smooth and accurate slitting operations:
Uncoiling: The steel coil is mounted on a hydraulic uncoiler.
Feeding and Leveling: The sheet is flattened and guided to the slitting head.
Slitting: Circular blades (rotary knives) cut the coil into multiple strips.
Tension Control: Keeps strip tension uniform during slitting and rewinding.
Recoiling: Each slit strip is rewound into smaller coils.
Stacking and Packaging: Coils are automatically discharged for packing or storage.
This continuous process ensures minimal material deformation and consistent width accuracy.

Faith Machinery’s metal slitting lines are used across multiple sectors:
Automotive Industry – For parts, frames, and structural strips.
Construction – For roofing panels, studs, and steel framing materials.
Appliance Manufacturing – For refrigerator panels, washing machine shells, etc.
Electrical Equipment – For transformer laminations and enclosures.
Pipe and Tube Production – For slitting coils before roll forming.
Packaging and Metal Service Centers – For coil distribution and reselling.
Precision in slitting depends largely on knife alignment and tension management.
Knife Alignment: Faith Machinery uses hydraulic knife positioning systems for quick and precise adjustments. Knife shafts are supported by heavy-duty bearings to maintain consistent gap settings during operation.
Tension Control: Pneumatic braking systems and load cells ensure equal tension across all strips, preventing coil telescoping and edge burrs.
These technologies result in cleaner cuts, minimal scrap, and improved overall efficiency.
Faith Machinery integrates Siemens PLC and HMI systems to enhance productivity and user control. Key automation features include:
Auto coil centering
Automatic knife positioning memory
Line speed synchronization
Safety interlocks and emergency stops
Real-time diagnostic and fault display
This ensures safe, reliable, and intelligent production operation.
