Decoiler/Uncoiler
The hydraulic automatic decoiler is equipped with hydraulic expansion, allowing the material's inner diameter to expand and contract automatically, saving time and effort.
Material width (mm): 100-1600
Material thickness (mm): 0-6.0
Product Characteristics
The hydraulic decoiler machine is designed for heavy-duty coil handling and high-efficiency automated stamping production. With a hydraulic expansion mandrel, intelligent tension control, and durable structural design, it ensures stable, safe, and damage-free coil unwinding.
This machine is widely used in 3C electronics, automotive parts, hardware stamping, and precision metal processing industries, and can be integrated into a fully automated coil feeding line.
The main shaft adopts a hydraulic expansion system, providing strong clamping force to securely hold coils of various inner diameters. This design improves operational safety while reducing manual labor.
Equipped with an automatic pressure-holding function, the decoiler effectively prevents coil loosening during operation, ensuring stable and continuous material feeding.
The hydraulic decoiler features:
Automatic braking to prevent inertia damage
Rack release limit protection to safeguard the hydraulic cylinder
These functions enhance equipment safety and reduce mechanical wear.
The four-blade structure matches the coil inner diameter precisely.
Combined with hard chrome-plated surfaces, it ensures:
Smooth expansion and contraction
High wear resistance
No scratches or damage to material surfaces
The A-frame adopts a fast replacement design, allowing quick and secure mandrel changes without damaging internal components.
The main motor uses a gear motor with vector frequency control, driving uncoiling via a sprocket system.
This ensures:
Smooth speed control
Stable coil feeding
Energy-efficient operation
The machine frame is built using:
Welded steel sections
A3 steel plates
#45 forged bearing blocks
All components are annealed for stress relief, ensuring long-term stability.
Precision boring ensures high concentricity, eliminating radial runout and improving operational accuracy.
The system automatically adjusts the coil rotation speed based on outer diameter changes, enabling:
Automatic acceleration and deceleration
Reduced mechanical load
Lower failure rate
Extended service life
In this production line, the MT Series Hydraulic Decoiler is paired with a precision coil leveler and servo roll feeder to form a fully automated coil feeding system for a 3C electronics stamping application.
The hydraulic decoiler ensures smooth and stable coil unwinding, while the straightener and servo feeder maintain excellent flatness and feeding accuracy. This fully automated setup significantly improves production efficiency and minimizes manual intervention.
This combination significantly enhances production efficiency, product consistency, and automation level, especially for 3C electronics precision stamping applications.

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.
