5 Axis Reciprocating UV Primer Spraying Line
1. Overview
Geetech’s UV Primer Spraying Line integrates precision 5-axis spraying with high-intensity UV curing in a single inline system. This combination drastically reduces floor space requirements and cycle times compared to traditional batch ovens.
2. Working Principle
- Parts enter the spray booth via an inline conveyor.
- The 5-axis reciprocator applies UV primer with high transfer efficiency.
- Parts immediately pass through a UV curing tunnel (365/395 nm).li>
- Instantly cured primers are ready for PVD or topcoat application.

4. Key Advantages
- Instant curing eliminates drying time
- Low VOC emissions comply with environmental regulations
- Reduced floor space compared to batch ovens
- Superior surface hardness for downstream processes
5. Quality Control
UV energy is monitored in real time using calibrated radiometers. Cured primers are tested for pencil hardness (ASTM D3363) and MEK resistance to ensure they meet the demands of subsequent PVD or painting processes.
