1. Product Overview**
A decoiler/uncoiler is a core equipment in metal coil processing lines, designed to smoothly unwind steel, aluminum, copper, and other metal coils for continuous automated production with downstream equipment like levelers, stamping machines, or cutters. It is widely used in automotive manufacturing, home appliance sheet metal processing, architectural curtain walls, packaging materials, and related industries.

3. Core Advantages**
- **High Efficiency & Stability**:
- Hydraulic expansion shaft or mechanical expanding mandrel design ensures rapid coil locking (<5 minutes for coil change).
- Variable frequency speed control + closed-loop tension control prevents scratches and misalignment during unwinding.
- **Broad Compatibility**:
- Processes cold-rolled steel, stainless steel, aluminum alloys, galvanized sheets, and more.
- Handles material thickness from 0.3mm to 6mm, ideal for precision thin-sheet processing.
- **Intelligent Control**:
- Optional PLC system synchronizes with downstream equipment (levelers, cutters) for fully automated production.
- Touchscreen interface monitors tension, speed, coil diameter, and other parameters in real time.
- **Safety & Durability**:
- Core components use quenched alloy steel for a lifespan exceeding 10 years.
- Dual anti-uncoiling mechanisms prevent accidental coil ejection.
