Zhongtuo Cut to Length Machine
Cut to length is a critical industrial system designed to process large-width metal coils into narrower strips with precise dimensions. Its primary function is to unwind, leveling ,slitting, and recoil metal sheets (e.g., steel, aluminum, or copper) to meet specific width requirements for downstream manufacturing applications.
The process begins by feeding a master coil into the decoiler. The material passes through a leveling unit to eliminate internal stresses and ensure flatness. Next, the slitting mechanism—equipped with rotating circular blades—precisely cuts the coil longitudinally into multiple narrow strips. These blades are adjustable to accommodate varying widths, thicknesses, and material grades. The slit strips are then rewound into individual coils via tension-controlled recoilers, ready for subsequent processes like stamping, forming, or welding.
This machinery is indispensable in industries such as automotive, construction, appliances, and electronics, where customized strip dimensions are essential for producing components like automotive frames, HVAC ducts, or electrical enclosures. Key advantages include high-speed processing, exceptional dimensional accuracy, minimized material waste, and automation-driven consistency. Modern slitting lines often integrate advanced sensors and CNC systems to optimize precision, reduce manual intervention, and enhance safety. By converting bulk coils into tailored strips, the slitting line bridges raw material supply and finished product manufacturing, ensuring efficiency and cost-effectiveness in high-volume production environments.

A. Hydraulic Decoiler
1.Automatic working
2.Hydraulic expansion
3.With press arm to keep the coil from loosing
4.With braking system and speed sensor to match the speed with other machines
5.Saving labor
B. Leveling device
The frame is divided into two parts, connected by four strong tie rods. The upper
stand is used to install the upper row leveling roll set. The lower frame is used to
install the lower leveling roll set and to support the whole body.
C. Slitting machine
The number of blades is customized according to the number of slitting, and the material of the blades is Cr12Mov, which ensures that the slitting effect is smooth and burr-free, and the accuracy of slitting is more accurate.
D. Side Wire Winding Machine
After the steel coil is divided into different widths, there will be edge wire waste on both sides, we are equipped with professional edge wire collection equipment, which can better collect the waste and improve the overall efficiency of the machine.
E. Tension Station
The tensioning station provides tension to the split steel coil to ensure the tightness of the winding and improve the efficiency of winding.
F. Hydraulic Recoiler
After the steel coil is divided, the tension is provided by the tensioner, and the coil is wound up by the winder. Our winder can adjust the snap according to the width of the steel coil to ensure the winding effect is neat and stable.
