Introduction

A 3-in-1 coil feed line, also known as a decoiler straightener feeder, integrates decoiling, leveling, and servo feeding functions into one automated system. Compared with traditional separate machines, this compact coil processing equipment provides better synchronization, higher feeding accuracy, and improved production efficiency for lithium battery case stamping.

What Is a 3-in-1 Coil Feed Line?

A 3-in-1 coil feed line is an integrated coil handling system that combines an automatic decoiler, precision straightener, and servo feeder into one compact unit.

Compared with traditional production lines using separate equipment, the integrated design provides synchronized material processing, higher feeding accuracy, and easier operation.

For lithium battery case manufacturing, the system ensures continuous feeding while maintaining stable material flatness throughout the stamping process.

Challenges in Lithium Battery Case Stamping

Typical production challenges include:

• Thin aluminum sheets deform easily

• High feeding accuracy is required

• Surface scratches must be avoided

• High-speed continuous stamping

• Frequent coil replacement

• Limited workshop space
