Need continuous high-speed stamping production? Coil feeding lines automate material handling from coil to press, enabling uninterrupted high-volume manufacturing with minimal operator intervention.

What is a Coil Feeding Line?

A coil feeding line is an integrated system that unwinds metal coil, straightens the material, and feeds it precisely into a press machine. This creates a continuous production flow ideal for high-volume stamping operations.

Coil Feeding Line Components

1. Decoiler (Uncoiler)

• Function: Holds and unwinds metal coil
• Capacity: 1-20 ton coil weight
• Features: Hydraulic expansion, brake tension control, edge guiding
• Options: Motorized drive, loading car, coil storage

2. Material Straightener

• Function: Removes coil curvature and internal stress
• Roller count: 9-21 rollers (more rollers = better straightening)
• Adjustment: Manual or motorized gap adjustment
• Material thickness: 0.3-6.0mm range

3. NC Servo Feeder

• Function: Precise material advancement into press
• Accuracy: ±0.05mm feed length
• Speed: Up to 200 feeds/minute
• Control: PLC with touchscreen interface

4. Loop Control System

• Function: Maintains proper material tension between straightener and feeder
• Type: Photocell or mechanical loop
• Benefit: Prevents material damage, ensures smooth feeding

5. Entry/Exit Tables

• Function: Support material before and after processing
• Features: Adjustable height, roller or belt surface
