Cut To Length Line

1. What is a Coil Cut to Length Line?

Coil cut to length line can cuts metal coils transversely according to the customer's actual needs, preparing the material for subsequent forming processes. The metal sheets produced by the coil cut to length line are generally used for single-stage forming processes, such as sheet metal stamping, bending, and stretching. This coil cut to length line mainly consists of precision components such as a decoiler, leveling machine, cut-to-length machine, waste collection device, conveyor belt, and stacker. KINGREAL continuously researches and innovates in the design and manufacturing of coil cut to length lines, offering personalized solutions such as coil cut to length machines equipped with double leveling machines, coil cut to length machines with laminating devices, and coil cut to length machines with double stackers, aiming to perfectly match customers' cutting needs.

2. What is a Coil Cut to Length Line in Manufacturing?

The precision metal sheets produced by coil cut to length lines are used in various fields. Based on the different market demands for sheet metal, KINGREAL offers light duty cut to length line (0.2-3mm), medium duty cut to length line (0.3-6mm), and heavy duty cut to length line (6-25mm). The thin sheets produced by the light duty cut to length line, due to their light weight and certain strength, can meet product appearance and lightweight requirements, and are often used in the manufacture of car bodies and home appliance panels. Medium-thickness sheets produced by the medium duty cut to length line are widely used in building structures such as bridges and house frames, as well as in machine tool beds in mechanical manufacturing, and can withstand large loads and complex stresses. Thick metal plates produced by heavy duty cut to length line are mostly used in the chassis of large engineering machinery and the manufacture of pressure vessels, ensuring high strength and safety with their robust material.

3.What is the Difference between Coil Cut to Length Line and Steel Slitting Line?

Both steel slitting machines and coil cut to length lines are common coil processing line, but there are significant differences between them. A coil cut to length line is mainly used for transverse cutting of coils. It uses a cut-to-length machine to precisely cut the coil at a preset length, and then uses a stacker to neatly stack the cut sheets. Coil cut to length machines are typically used to produce precision sheet metal, with subsequent processing generally involving single forming processes such as sheet metal stamping, bending, or stretching. In contrast, steel slitting machines focus on longitudinally cutting coiled materials. Depending on the customer's specific needs, steel slitting machines can cut wide coils into narrow strips of varying widths. The cut coils are then rewound by a recoiler for subsequent secondary processing or long-distance transportation. These narrow strips are often used in continuous production, such as automatic stamping, rolling, and secondary longitudinal and transverse cutting. In terms of production efficiency, steel slitting lines can reach a maximum production speed of 230m/min, while the maximum operating speed of coil cut to length lines is typically 80m/min.

4. How to Choose Coil Cut to Length Line?

-Processing Accuracy: Processing accuracy directly relates to the performance and application effect of the coil cut to length machine. When selecting coil cut to length line, it is crucial to focus on whether the coil cut to length line can accurately control the cutting length, with the error range controlled within ±0.1mm. The coil cut to length machine should minimize burr generation to avoid affecting stacking effects and electromagnetic properties. The cut metal sheets should remain flat to prevent misalignment from affecting subsequent splicing or stacking processes.

- Automation Level: Highly automated coil cut to length lines can significantly improve production efficiency and reduce human intervention, thereby lowering the probability of operational errors. When purchasing, attention should be paid to whether the coil cut to length line supports automatic feeding and automatic sheet separation functions to reduce manual operation. The coil cut to length machine should be equipped with a PLC or CNC control system to achieve automatic parameter adjustment and fault alarms, ensuring the continuity and safety of production. Furthermore, the coil cut to length machine should ideally have the ability to monitor cutting quality in real time to ensure consistent product quality.

- Equipment Stability and Durability: Coil cut to length lines usually need to operate continuously for long periods, so equipment stability and durability are very important. When purchasing, special attention should be paid to the material of key components, such as the cutters and guide rails. These main components should be made of high-strength alloy materials to ensure long-term use without significant wear. The coil cut to length machine design should also facilitate daily maintenance and replacement of wear parts, thereby reducing production losses due to downtime.

- Production Efficiency: When choosing a coil cut to length line, it is very important to determine the appropriate cutting speed based on production needs. High-speed coil cut to length line is more suitable for large-volume production. In addition, it should be considered whether the equipment supports the processing of metal materials of different thicknesses and widths to adapt to diverse production needs.

- After-sales Service and Technical Support: Good after-sales service can effectively reduce losses caused by coil cut to length line failures. Taking KINGREAL as an example, KINGREAL provides customers with a series of after-sales services, including machine installation and operation training. They also provide long-term spare parts supply after tools and other components wear out. They also clearly define the warranty policy with customers, effectively avoiding subsequent disputes and troubles.
