Heavy Equipment Coating Challenges
- large part dimensions (2-12m) requiring extended robot reach
- thick film build requirements (100-200+ microns) prone to runs and sags
- heavy weld seams, sharp edges, and complex geometries
- corrosion protection critical for outdoor/harsh environment operation
- inconsistent coverage in recessed areas and interior surfaces
- high paint consumption with manual spraying on large surfaces
- skilled labor shortage for large-scale spray operations
System Approach for Large Parts
- 7th-axis rail systems extending robot reach to 8-12+ meters
- multi-robot configurations for simultaneous painting of large assemblies
- heavy-duty turntables and positioners for part rotation
- high-flow spray guns for thick film builds (airless, air-assisted airless)
- large-format booth design with proper airflow for oversized parts
- recipe management for mixed-model production
