Decoiler/Uncoiler
The MT Series Heavy-Duty Hydraulic Decoiler (Automatic Uncoiler) is engineered for high-capacity coil handling in roll-forming and stamping production lines. Supporting material widths of 100–1600 mm and thickness up to 6.0 mm, with hydraulic expansion and an optional coil loading carriage, the MT Series reliably feeds heavy coils (up to 20,000 kg) to straighteners and servo feeders for continuous, automated production.
Material width (mm): 100-1600
Material thickness (mm): 0-6.0
The automatic hydraulic decoiler is used for loading or unloading large metal coils, with an adjustable inner diameter of the material. It is designed with a loading trolley for quick and convenient loading and unloading.
Product Characteristics
The Heavy Duty Hydraulic Decoiler with Coil Loading Car is designed for stable, efficient, and automated metal coil unwinding in modern roll forming and sheet metal processing production lines. The machine is widely used in industries such as construction materials, ceiling systems, steel framing, appliance manufacturing, automotive parts, and metal stamping production.
The decoiler adopts a heavy-duty steel welded structure combined with a hydraulic expansion mandrel system, ensuring stable coil support, smooth uncoiling, and long-term durability during continuous production.
Integrated with an automatic coil loading car, the system significantly reduces manual handling while improving loading efficiency, production safety, and material feeding stability.
This automatic decoiler is suitable for processing steel coils, galvanized coils, stainless steel coils, aluminum coils, copper coils, and other metal materials.
The machine body is manufactured using high-strength steel plates with bevel preparation before welding.

Safer production environment
The loading trolley works synchronously with the decoiler to achieve efficient automatic material preparation.
In this project, the MT Series Heavy Duty Hydraulic Decoiler is integrated with a roll forming machine to create a fully automated production line for metal keels used in the construction industry.
The system enables efficient coil loading, uncoiling, forming, and cutting—all in one continuous process. With the support of a hydraulic expansion decoiler and automatic coil loading carriage, this solution ensures stable and uninterrupted material feeding, greatly improving productivity and reducing manual handling.
This case demonstrates the application of an automated coil feeding solution in the building materials industry, enabling large-scale production of light steel framing components such as wall studs, ceiling grids, and other structural keels.

FAQ
Q: How do I determine the right feeder size for my production line?
A: The feeder size depends on the material width, thickness, and feeding step distance required by your stamping press. Choosing the correct specifications ensures smooth operation and prevents feeding errors or misalignment.
Q: What factors should I consider when choosing a servo feeder machine?
A: When selecting a servo feeder, key factors include feeding accuracy (±0.05mm or better), maximum feeding speed (e.g., 20m/min), material compatibility (stainless steel, aluminum, etc.), load capacity, and control system (PLC or touchscreen). Ensure the machine matches your stamping process requirements.
Q: How do I choose the right decoiler, straightener and feeder?
A: Select based on material type, width, thickness, coil weight, and required speed. Match decoiler capacity to coil size, choose a straightener for material strength, and a feeder that meets feed length and precision. Ensure compatibility with your press and automation level.
Q: Coil feeder vs servo feeder: what’s the difference?
A: A coil feeder is a broader system for continuous coil feeding, often integrated with decoiler and straightener. A servo feeder uses servo motors for precise, programmable feeding, ideal for short pitches and high accuracy applications.
Q: How to choose decoiler capacity?
A: Select a decoiler rated 10–20% above your maximum coil weight. Confirm inner diameter (I.D.) compatibility and outer diameter limits. Adjustable mandrels are recommended if you run multiple coil sizes.
Q: What feed precision can I expect?
A: Servo feeders typically achieve ±0.01–0.05 mm, with high-end models reaching ±0.005 mm. Mechanical feeders usually provide ±0.02–0.1 mm. Actual accuracy depends on material properties and straightening quality.
Q: How does material affect machine selection?
A: High-strength materials need stronger straightening and drive systems. Thin materials require low-pressure handling. Soft materials like aluminum need anti-scratch solutions.
Q: What affects feeding accuracy most?
A: Key factors include feeder precision, servo tuning, straightener setup, material quality, and press stability. Poor setup or worn dies can reduce accuracy.
Q: What spare parts should be prepared?
A: Common spares include bearings, belts, sensors, seals, guide blocks, and lubrication parts. Keeping key components reduces downtime and improves maintenance efficiency.
Q: Can feeders be retrofitted to existing presses?
A: Yes, most systems support retrofitting. Check press dimensions, feed height, control compatibility, and safety requirements before installation.
Q: How long does it take to receive the feeder machine after placing an order?
A: Lead time for delivery typically ranges from 4 to 8 weeks depending on customization, production schedules, and shipping location. Once your order is confirmed, we will provide a more precise delivery estimate.
Q: What are your payment terms?
A: We accepts T/T payment, 30% deposit and 70% balance before shipping
Q: How often should I perform maintenance on my servo feeder machine?
A: Routine maintenance should be conducted weekly for basic cleaning and lubrication, while a more thorough inspection should be done monthly to check for wear on rollers, belts, and electrical components. A full servicing is recommended every 6-12 months depending on usage intensity.
Q: What are the most common issues with feeder machines, and how can I troubleshoot them?
A: Common issues include misalignment, inconsistent feeding accuracy, or motor failure. Check for loose bolts, dirt buildup, or software calibration errors. If problems persist, refer to the user manual or contact technical support.
Q: Do you provide on-site repair services if my machine breaks down?
A: Yes, we offer on-site repair services for major issues, along with remote troubleshooting support for minor problems. For urgent cases, we can dispatch a technician within 24-48 hours, depending on your location.
Q: What is the maintenance cycle?
A: Daily cleaning and inspection; weekly check belts, air lines; monthly inspect bearings and guides; yearly replace worn parts. Adjust frequency based on operating hours and workload.
Q: What's the package of your coil feeding machines?
A: For the coil feeding equipment that go LCL shipping, We will use plastic films wrap on the equiment, and then fix it into a wooden box.
For the large coil lines that go FCL shipment, We will fix each part with ropes on the shipping container and then wrapped them with plastic films.
Q: What is the typical lead time?
A: Standard machines usually take 4–8 weeks. Customized systems or full production lines may require 10–20+ weeks depending on complexity and production schedule.
