1. Introduction

As the automotive industry moves toward lightweight, high-strength, and precision manufacturing, stamping lines are demanding higher accuracy and efficiency in coil handling. Traditional separate decoiler, straightener, and feeder setups take up large floor space and require complex adjustments — making them less suitable for modern automotive parts production.

The Thick Plate 3 in 1 Coil Feeding Line by Youyi integrates decoiling, leveling, and feeding into a single intelligent system. Specially designed for high-strength steel and thick plate materials, this compact coil handling solution helps automotive parts manufacturers achieve higher precision, faster production, and improved automation efficiency.

2. Structure and Key Features of the Thick Plate 3 in 1 Coil Feeding Line

The Thick Plate 3 in 1 Coil Feeding Line combines three major coil-handling functions — uncoiling, leveling, and feeding — into one integrated unit, achieving continuous automatic operation with multiple advantages.

High Adaptability Design

Coil width: 70–1300 mm

Coil thickness: 0.6–6.0 mm
Capable of processing a wide range of materials including high-strength steel, galvanized sheet, and stainless steel, commonly used in automotive component manufacturing.

High-Precision Leveling System

Built with a rigid frame and precision-adjustment mechanism, the straightening rollers are made of high-quality bearing steel, chrome-plated, and ground for durability. This ensures uniform stress relief and scratch-free surfaces during the leveling of thick plate materials.

High-Efficiency Servo Feeding

Equipped with a servo motor and synchronized feeding rollers, the system provides high-speed and high-precision coil feeding. The closed-loop control ensures quick response and accurate positioning during high-speed stamping operations.

Compact and Energy-Saving Design

The integrated and modular layout significantly reduces floor space by about 30% compared with separate-type lines. It also minimizes wiring and shortens coil changeover and setup times.

Safety and Intelligent Control

Features include an automatic press arm, coil support device, and user-friendly HMI touch screen. Operators can monitor system diagnostics and automate line adjustments, improving operational safety and reliability.

3. Application Value in Automotive Parts Production

1. Supporting High-Strength Steel Stamping

Automotive components such as chassis parts, bumper beams, and reinforcement plates often use high-tensile materials. The Thick Plate 3 in 1 Coil Feeding Line effectively removes internal coil stress and ensures excellent flatness, providing stable material input for precision stamping dies.

2. Improving Production Efficiency and Consistency

The automatic linking of decoiling, leveling, and feeding eliminates manual coil transfer, achieving continuous operation and improving production rhythm. It is especially suitable for large-scale automotive part stamping lines requiring high productivity.

3. Reducing Setup and Maintenance Costs

The integrated design reduces mechanical interfaces and control wiring, simplifying installation and maintenance. Operators can quickly change coil or mold parameters via the touch screen, improving line flexibility and reducing downtime.

4. Ensuring Product Quality and Precision

With precisely machined and scientifically arranged leveling rollers, the system prevents surface damage such as scratches or dents during feeding, ensuring consistent dimensions and excellent surface quality for visible automotive parts.

4. Industry Applications and Results

The Thick Plate 3 in 1 Coil Feeding Line has been widely adopted in various automotive part production lines, including:

Chassis structural component stamping

Bumper and reinforcement beam forming

Door impact bar and suspension bracket production

Battery tray and new energy vehicle structural parts processing

Field data shows that after implementing the Thick Plate 3 in 1 Coil Feeding Line, manufacturers experience:

Over 30% increase in production efficiency

10–15% improvement in material utilization

Significant reduction in setup and adjustment time

These benefits translate directly into higher productivity and profitability for automotive component manufacturers.

5. Conclusion

With the growing demand for intelligent and efficient manufacturing, the Thick Plate 3 in 1 Coil Feeding Line stands out as a core solution in automotive stamping automation. Its precision, high efficiency, and low-maintenance operation meet the strict requirements of thick plate processing, empowering manufacturers to build flexible, intelligent, and high-performance production lines.
