Product Characteristics
The Automatic Cut to Length Line for Hydrogen Fuel Cell Bipolar Plate Production is a customized coil processing system designed to cut metal coils into precise sheet lengths for bipolar plate manufacturing.
Bipolar plates are essential components of hydrogen fuel cells and electrolyzers. Their manufacturing process requires consistent sheet dimensions, reliable feeding accuracy, and careful surface protection to maintain product quality and support subsequent forming operations.
Developed by YouYi Precision, this automatic cut to length line integrates coil decoiling, precision straightening, servo feeding, pneumatic shearing, material conveying, and automatic stacking into one coordinated production system.
Designed for processing stainless steel, titanium alloy, and other metal materials, the production line provides stable material handling and automated cutting operations while minimizing surface scratches, dents, and other handling defects.
It is particularly suitable for manufacturers seeking an integrated solution for metal sheet preparation in hydrogen fuel cell bipolar plate production.
The automatic cut to length line consists of four main sections:
Automatic Decoiler: Unwinds and supports metal coils, providing continuous material supply.
Servo Straightener & Feeder: Levels the coil material and feeds it forward according to preset lengths.
Precision Pneumatic Shearing Machine: Cuts the material into required sheet lengths.
Automatic Conveyor & Stacking System: Transfers and stacks finished sheets for convenient collection and subsequent processing.
By coordinating these sections, the production line reduces manual material handling and helps improve production consistency.
The automatic decoiler provides stable coil support and controlled unwinding throughout the production process. Its safety-oriented structure helps prevent coil loosening and improves material loading efficiency.
Main Features:
Hydraulic expansion with a safety chuck for secure coil clamping.
Pneumatic pressing arm to prevent coil loosening during decoiling.
Hydraulic loading car for convenient coil loading and unloading.
AC motor drive with frequency converter for controlled unwinding.
Pneumatic disc brake for stable braking and tension control.
The servo straightener and feeder combines material leveling and precision feeding functions. It prepares the metal strip for shearing while maintaining consistent feeding performance.
The system uses a Yaskawa servo motor, Mitsubishi PLC, and a 7-inch touchscreen to provide accurate feeding control and convenient parameter adjustment.

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.
