The traditional method of sheet metal processing is to use a decoiler to uncoil and level the sheets, and then send them to a shearing machine to cut them into sheets of a certain length. Finally, the materials are manually transported to the laser cutting machine for cutting and blanking. Most existing laser cutting machines can cut various shapes, but when cutting, the sheet is stationary, and the incoming and outgoing materials cannot be carried out at the same time, which affects the processing speed of the sheet.
The production line of the uncoiling and leveling laser cutting machine can achieve four functions of uncoiling and leveling, feeding, cutting, and cutting in one, breaking the traditional processing method, that is, the laser cutting machine is used for flying cutting during the movement of the strip. The purpose is to solve the problem of rapid cutting of continuous metal strips without molds, thereby reducing the investment and consumption costs of cutting equipment and molds, and effectively improving material utilization.
The laser automated production line for uncoiling and leveling is usually composed of uncoilers, leveling machines, laser cutting machines, conveying devices, etc. Among them, the unwinding machine is used to unfold the metal coil, and the leveling machine performs leveling treatment on it. The laser cutting machine cuts the metal sheet according to the preset processing dimensions. These devices are usually equipped with automated control systems and sensors to achieve high-precision processing and production control.
The coil laser cutting equipment mainly consists of automatic unwinding, leveling system, servo automatic feeding, laser cutting system, automatic assembly line, online coil cutting, saving labor, improving efficiency, etc.
The CNC laser cutting machine adopts a professional system to control motor synchronization. The cutting machine workbench is a track type cutting table, which is equipped with needle plate cutting strips. During the processing, the cutting table and the unwinding servo feed are synchronized and run at the same speed to achieve plate cutting.
The body of the CNC laser cutting machine adopts a steel plate welding structure, which is subjected to high-temperature tempering treatment to completely eliminate welding stress.
The leveling machine's correction wheel is made of bearing steel, with a thickened and electroplated surface, which is durable and wear-resistant. Easy and convenient to operate, all correction wheels are equipped with gear transmission and spare pressure wheels, which can effectively enhance the rigidity of the correction wheels and improve the quality of correction.
The feeding and cutting system of the leveling machine, as well as the automatic stacking system, can adapt to the production of various metal material parts and billets.
Due to the use of coil materials for continuous production, there is no loss of material head and tail under single piece conditions. Meanwhile, the equipment adopts optimized layout. Combine various shapes of parts for edge free cutting to reduce material loss and improve material utilization.
It can cut carbon steel plates, stainless steel plates, aluminum plates, especially high-strength steel plates that are difficult to be stamped with a punching machine.
The advantages of the decoiling and leveling laser automated production line are its high degree of automation, high precision and high efficiency. This kind of production line can greatly reduce the labor intensity of workers and improve production efficiency and product quality. At the same time, due to the use of laser cutting technology, the processing accuracy and cutting speed can be greatly improved, further improving production efficiency.
In addition, the uncoiling and leveling laser cutting automated production line also has the characteristics of easy operation and simple maintenance. This kind of production line is usually equipped with a touch screen or computer interface, and the operator can complete the adjustment and control of the equipment through simple operations. At the same time, the equipment has a simple structure, fewer parts, and is relatively easy to maintain.
In actual use, the decoiling and leveling laser cutting automatic production line is further subdivided according to the different sheet metal materials of the enterprise. Products produced using automated production lines should have a large enough output, and product design and technology should be advanced, stable, reliable, and remain basically unchanged for a long time.
The use of automated production lines in mass production can increase labor productivity, stabilize and improve product quality, improve labor conditions, reduce production area, reduce production costs, shorten production cycles, ensure balanced production, and improve economic benefits. If the product batch is small and the varieties are not fixed, it is recommended to use a semi-automatic production line.
In short, the uncoiling and leveling laser cutting line is an efficient, high-precision, and highly automated production line that is suitable for the processing and manufacturing of various metal sheets. With the continuous advancement of science and technology and the continuous development of industrial production, this kind of production line will become more and more popular and become one of the important development directions of future industrial production.
The automotive industry is rapidly evolving, driven by the demand for faster production, superior quality, and greater flexibility. Among the most impactful innovations in recent years is the laser coil cutting line—an integrated solution that combines decoiling, leveling, feeding, cutting, and unloading of sheet metal coils. This advanced technology is transforming automotive manufacturing by improving material utilization, accelerating changeovers, and enabling greater design versatility.
A laser coil cutting line is a fully-automated system that deals with sheet coils by using its decoiler, leveler, feeder, laser cutter and unloading devices. Unlike mechanical blanking presses, which require hard tooling (dies) to punch out shapes, laser blanking is tool-free, meaning it uses software-driven laser beams to define the cutting geometry.
laser coil cutting lines typically include:
Combining decoiling, leveling, feeding, cutting and unloading together, the blanking line has developed into a one-stop production line from mere cutting and a sharp weapon to cut most sheet coils.
Generally speaking, laser coil cutting line is equipped with common laser cutting machine, but, SENFENG can accept customization of two decoilers, two, three or four crossbeams & laser cutting heads, in this way, sheet leveling and cutting speed is greatly raised.

In general, the automotive industry faces several unique challenges:
Traditional stamping lines struggle with these demands because of their dependency on heavy tooling, long changeover time and high costs for tool maintenance and storage. This is where laser coil cutting lines offer a transformative solution.
One of standout features of laser coil cutting line is its elimination of mechanical dies. All cutting paths are defined digitally, allowing manufacturers to adapt quickly to all changes with no need to fabricate or modify tooling. This offers several advantages:
For example, if a car manufacturer wants to change the geometry of door panel or body, engineers only need to update the digital files before starting production, with no downtime or tooling costs involved.
laser coil cutting lines allow for intelligent nesting, where parts shape is arranged digitally to maximize the used materials. However, traditional blanking dies require rectangular blanks with fixed dimensions, leading to more scraps.
With laser coil cutting lines, manufacturers can:
This is particularly valuable while dealing with expensive or lightweight materials such as aluminum and high-strength steels, which are widely used in modern vehicle structures.
The laser cutting line delivers exceptional edge quality, producing burr-free and clean cuts that often eliminate the need for secondary processing. This is especially crucial in automotive manufacturing, where strict tolerances and structural integrity are essential.
Its high-precision cutting enhances downstream operations such as welding, forming, and assembly, helping to minimize defects and reduce rework throughout the production line.
Since there is no physical tool to replace, changing from one part to another is nearly instantaneous. Changeovers can be done by simply loading a new cutting program into the system, allowing for:
This flexibility aligns with the automotive industry’s move towards modular platforms and personalized vehicle configurations.
Electric vehicle (EV) makers are now placing heavy emphasis on reducing vehicle weight to prolong driving range. As a result, materials like aluminum, advanced high-strength steel (AHSS) and composites are increasingly used in body structures.
laser coil cutting lines are ideal for these materials, as they offer:
This makes laser coil cutting line a strategic helper for EV production lines and sustainable vehicle manufacturing.
laser coil cutting lines are widely used across various automotive sectors, such as:
Because laser coil cutting line handles multiple types of materials and part geometries, it allows automakers to consolidate multiple stamping operations into a single flexible line.
Although upfront costs of laser coil cutting lines are usually higher than other traditional press systems, the long-term ROI is attractive, especially for automakers that:
laser coil cutting lines also reduce capital expenses related to tooling, shorten time-to-market, and lower operating costs through automation and improved throughput.
As the automotive industry transitions toward electric mobility, lightweight materials, and custom-made manufacturing, laser coil cutting lineis still developing into a key enabler of agility and innovation.
