Tunnel Powder Coating Booth – High-Volume Production Solutions

1. Tunnel Powder Coating Booth Overview

A Tunnel Powder Coating Booth is a continuous conveyorized system designed for high-throughput industrial coating applications. Key features include:

• Enclosed conveyor tunnel for consistent airflow

• Automated powder application with robotic or fixed guns

• Integrated curing oven for inline processing

• Tunnel Powder Coating Booth recovery systems (cyclone or cartridge filter)

Ideal for mass production of automotive parts, appliances, and metal furniture.

2. Key Benefits

✔ High production capacity (500–2,000+ parts/day)
✔ Uniform coating quality with controlled environment
✔ Reduced labor costs via full automation
✔ Energy-efficient powder recycling (up to 98% recovery)

3. Tunnel Powder Coating Booth System Components

• Pre-treatment zone (cleaning, phosphating)

• Powder application tunnel (electrostatic guns)

• Curing oven (convection or infrared)

• Conveyor system (overhead or floor-mounted)

• Powder reclaim system (cyclone/filter-based)

4. Pricing & ROI

ROI Factors:

• Higher throughput vs. batch systems

• Lower per-unit coating cost

• Minimal manual intervention

5. Tunnel Powder Coating Booth Operation & Maintenance

Best Practices:

• Maintain 80–120 FPM airflow for optimal powder containment

• Calibrate guns weekly for consistent deposition

• Clean reclaim filters daily (if using cartridge systems)

Maintenance Schedule:

• Daily: Check conveyor alignment

• Weekly: Inspect gun electrodes

• Monthly: Clean cyclone chambers

6. Leading Manufacturers
