Are you facing troubles like coil slipping, inner wall damage, or uneven feeding in your roll forming or stamping line? I get it – these issues waste material, slow down production, and drive your costs up. The good news is, there’s a reliable solution that can turn things around. Let me walk you through ourhydraulic decoiler with press arm– a machine built to handle heavy coils smoothly, safely, and smartly.
What is a Hydraulic Decoiler?
The Hydraulic Decoiler is a type of industrial machinery designed to secure and uncoil metal coils—such as those made of steel, aluminum, or similar materials—for use in automated production lines. It utilizes a hydraulic system to expand its mandrel, thereby firmly gripping the coiled material, and provides a smooth, controlled feed to downstream production machines, such asC&Z Purlin Making Machines,Hydraulic Slitting Lines, orAutomatic Cable Tray Roll Forming Machines.
Features & Components
·Hydraulic Mandrel:The central shaft expands and contracts using hydraulic pressure to secure the coil tightly from the inside, preventing damage.
·Automatic Operation:Uses sensor-driven, automatic start/stop and speed regulation, which is more reliable than manual tensioning.
·Capacity:Designed to handle heavy-duty loads, commonly ranging from 2 up to 25 tons, often equipped with an optional coil loading car to improve safety and efficiency.
·Tension Control:Includes systems to manage the slack, rebound, and tension of the material as it is released, ensuring a consistent, straight output

Component Advantages and Real Gains
Let me walk you through the parts that make this decoiler different – and how each one helps you save time, protect material, and run a safer line.
Slider-Type Tensioning System
We ditched the old four-jaw design. Instead, hydraulic sliders move radially to give stronger support.What this means for you:No more slipping or inner wall damage, even with heavy steel coils.
Removable Adjustment Gaskets
Different factories, different inner diameters. Just add or remove gaskets to change the ID range.What this means for you:One machine handles multiple coil sizes. No extra cost for a second decoiler.
Reinforced Main Frame with Support Arm
The main frame has an extrastrong support arm that spreads the cantilever load evenly.What this means for you:No shaft sagging or bending over time. Higher realworld load capacity and a machine that lasts longer.
Pneumatic Brake + Wireless Remote
A pneumatic brake matches the decoiler’s speed to your forming machine automatically – no pileups, no snapped strips. And all hydraulic actions (lifting, expansion, braking) run from a wireless remote.What this means for you:Perfect synchronization, and your workers can stand back from moving parts. Safer and easier.
So, what do you get from these features on your shop floor?
Less waste– No crushed inner coils or surface scratches.
More running time– Fewer breakdowns and stops.
A safer workplace– Remote control and automated loading keep people away from pinch points.
Easy operation– The VFD lets anyone adjust speed in seconds.
Fast payback– Lower scrap, less labor, consistent quality. Savings start from day one.
What Materials Can This Machine Process
Our hydraulic decoiler works with:
Hot rolled and cold rolled steel
Galvanized steel and stainless steel
Aluminum coils
Copper and brass strips
Pre painted metal sheets
Use it for: roofing sheets, C/Z purlins, cable trays, automotive panels, ducts, appliance shells, and many more profiles.
Frequently Asked Questions
Q: What is the physical size of the machine? How much floor space do I need?
A: The main machine is 3.4 meters long, 1.6 meters wide, and 1.8 meters high. Make sure you have extra room for the loading cart and material flow.
Q: How is the main frame built? Is it strong enough for daily heavy use?
A: Yes. The base is made of 300 H beam steel, and the box body is welded from 16 mm thick steel plates. Very sturdy.
Q: What material is the expanding mandrel made of?
A: The main shaft is machined from a thick wall seamless steel tube, with a diameter of 203 mm and wall thickness of 55 mm. It is strong and resists bending.
Q: Can I choose a hydraulic decoiler with a different weight capacity?
A: Certainly. We can customize it according to your specific requirements—including tailoring it to the specifications of your materials.
