The machine is especially suitable for electronic components, precision hardware, electrical terminals, and other light-duty stamping applications requiring compact equipment and consistent feeding performance.
Designed for easy installation and low maintenance, the CR Series helps manufacturers improve production efficiency while reducing manual material handling.
The CR Series Light Duty Decoiler/Uncoiler is a compact decoiler for electronics stamping lines, designed for automatic feeding and rewinding of thin metal coils and non-metal sheet materials up to 1.0mm in thickness. It is an ideal light duty coil holder machine for small and medium stamping automation systems where precision, stability, and space efficiency are essential.
This thin metal coil Uncoiler adopts a vertical pole support structure, with the reducer directly connected to the motor through a coupling output mechanism, ensuring smooth coil rotation and precise control of material feeding. Featuring a small footprint, easy installation and debugging, high reduction ratio, and stable operation, it delivers reliable performance with minimal maintenance and a low failure rate.
Its compact vertical design effectively reduces floor space usage, while the winding drum—composed of multiple support rods with radial contraction capability—provides quick and safe material loading. The system adopts a worm gear reduction and direct motor connection structure for efficient torque transmission and long service life.
Equipped with a simple yet adjustable material support device and a 24V vertical sensing bracket for automatic control, the machine can also be managed via a microswitch for waste material collection. These features make the CR Series a versatile and durable solution for light-duty coil feeding and precision stamping automation lines.

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.
