Dowell automatic coil production line integrates uncoiling, leveling, servo feeding and laser cutting into one intelligent system. It reduces labor cost, minimizes material waste, and significantly improves overall efficiency, making it the ideal upgrade for modern metal processing factories.
The initial feed roll is leveled by a leveling machine before entering the laser cutting platform for cutting. After cutting, the leveling machine automatically feeds the material, and the rotating platform automatically transports the cut parts to the receiving platform. After the leveling machine finishes feeding, the system runs to cut the second layout drawing material. At the same time, the numbering and collection of the first material can be performed. This process is repeated to greatly improve the overall processing speed and efficiency.
An uncoiler is an essential piece of equipment in an automated sheet metal production line. Its functions are twofold: first, to support the steel coil by tightening its inner bore; and second, to feed the end of the steel strip into the leveling machine through rotation in conjunction with a straightener. The uncoiler’s main shaft has two functions: driving the steel coil to rotate and providing tension and support.
The leveling machine is based on the Bauschinger effect of metal materials. It eliminates the original curvature difference of the sheet material by repeatedly bending it with multiple rollers. It adopts a non-parallel roller structure and is specially designed to adjust and correct various planes to a precise level. It can process a variety of metal materials such as stainless steel, copper, and iron, and significantly improve their flatness, accuracy, and surface quality.
The cutting unit adopts a new type of fiber laser (electro-optical efficiency up to 37%), a fully enclosed laser cutting head, a high-strength bed, a reverse-tooth rolling transmission, and a double aluminum alloy crossbeam structure, which is more energy-efficient and environmentally friendly, with faster cutting speed and longer service life.
Automatic rotary laser cutting machine: includes a coil rack, leveling device, laser machine bed, receiving platform, and automatic blade rotation assembly.

The Dowell Laser Automatic Coil Flattening & Laser Cutting Production Line is a fully automated integrated production line for processing metal coils. Its core function is to automate the entire process from coil loading to precision leveling, accurate feeding, and high-speed cutting, requiring minimal human intervention. This significantly improves production efficiency and processing accuracy while reducing labor and material costs, making it suitable for the large-scale, high-precision production needs of various metal processing companies.
Below, we will break down the four core components of the production line, clarifying the role and advantages of each part, and how they work together to form a complete production loop:
This single-cantilever hydraulic expansion and contraction uncoiling equipment is designed specifically for metal coil processing production lines. It comes standard with an end auxiliary support device to solve the problems of sag deformation, vibration, and spindle wobble of large-tonnage, wide-width, and large-outer-diameter steel coils in a single-cantilever state. It achieves high-speed, stable, and continuous uncoiling and is compatible with automated production lines, including laser cutting, leveling, stamping, and slitting.
Designed for high-precision leveling of thin sheets, stainless steel, aluminum sheets, galvanized sheets, etc., it adopts a three-upper-three-lower six-roller system structure, combined with a middle support micro-adjustment roller, to effectively eliminate internal stress, waviness, warping, and twisting, achieving ultra-high flatness precision leveling. It is the core precision equipment of the coil laser cutting production line.
This high-precision CNC servo feeding equipment adopts a multi-roller clamping structure, ensuring smooth, non-slip, and material-free feeding. The servo motor features closed-loop control, providing high positioning accuracy, precise feeding length, and fast response. It can achieve continuous and stable automated feeding, significantly improving the efficiency and processing precision of the entire production line.
This high-power, high-speed fiber laser cutting machine boasts an ultra-high power of 12000W, enabling faster cutting of thick plates with smoother, taper-free surfaces. Suitable for various metals, including carbon steel, stainless steel, aluminum alloy, copper, and more, it offers strong thick plate cutting capabilities, high efficiency, and excellent stability. When paired with an automated roll production line, it can achieve continuous, high-speed production around the clock.
This integrated laser processing production line consists of four highly coordinated modules: automatic loading, precision leveling, high-performance laser cutting, and intelligent unloading.
From coil loading, uncoiling, and high-precision leveling to high-speed servo feeding and automatic laser cutting, every step is optimized for maximum productivity. This closed-loop processing flow helps you achieve stable quality, zero tailings, smooth cutting, and high material utilization, enabling higher output at lower operating costs.
Function: Transports steel coils from the loading station to the uncoiler.
Key Features: Typically has a load capacity of 10-30 tons; features a V-shaped saddle design to prevent coil rolling; equipped with a coil width detection sensor for automatic centering.
Function: Unwinds steel coils at a constant speed and feeds a continuous strip into subsequent processing stages.
Key Features: The expanding mandrel secures the inner diameter of the coil and generates uncoiling tension (typically 3,000–8,000 N).
Function: Eliminates internal stresses within coiled material by repeatedly bending the steel strip using multiple sets of staggered rollers, thereby ensuring the flatness of the sheet metal.
Function: Stores a specific length of steel strip to ensure a continuous supply of material to downstream processes during coil changes at the uncoiler, thereby enabling non-stop production.
Function: Precisely feeds the leveled steel strip into the laser cutting zone according to a preset length.
Key Features:
Driven by a servo motor and transmitted via a ball screw, achieving a positioning accuracy of ±0.02 mm/m.
Function: As the steel strip moves continuously, the laser head dynamically tracks its motion to perform the cut, thereby achieving “flying cutting.”
Eliminates the acceleration and deceleration time associated with “stop-and-go” operations, boosting effective laser utilization from 50% to over 85%.
Function: Automatically sorts and stacks finished parts, and automatically recovers scrap material.
Key Features: Visual recognition system distinguishes between different parts and classifies them according to pre-set rules.
Traditional stamping and blanking rely on molds, high investment, long mold-making cycles, and limited flexibility for small-batch production. It also generates significant noise, requires frequent mold maintenance, and has limitations in processing complex shapes.
Dowell laser coil-fed blanking line realizes fully automatic uncoiling, leveling, feeding, laser cutting, and blanking in one continuous process. It needs no molds, supports flexible processing of any complex graphics, greatly reduces mold cost and production preparation time, improves material utilization, and achieves quieter, more precise, and more efficient blanking for modern sheet metal factories.

Machining accuracy
±0.3mm~0.5mm, easily affected by die wear deviation
±0.1mm, Laser cutting + servo positioning ensures precision throughout the entire process.
Sheet flatness
No dedicated leveling process results in wavy edges and residual internal stress, easily leading to pot deformation.
Multi-roller leveling technology ensures flatness error ≤0.1mm/m, eliminating substrate defects.
Material utilization
High material loss at the beginning and end, scrap rate 8%~12%.
Continuous cutting eliminates waste, reducing scrap rate to 2%~3%, saving 5%~8% of materials.
Production flexibility
Custom molds are required, resulting in high switching costs and difficulty adapting to irregular designs.
Mold-free cutting allows for rapid response to different sizes.
Production efficiency
Manual feeding and sorting are inefficient and limit capacity.
Fully automated process increases efficiency by over 30%, adapting to high-volume order demands.
Environmental safety:
Stamping noise ≥90 decibels, waste spillage causes pollution.
Cutting noise is as low as 75 decibels, waste is automatically recycled, meeting environmental standards.
