Semi-automatic powder coating system | Batch system with chemical pre-treatment & curing oven

Compact, semi-/partially automatic batch powder coating system for steel components (1,500 x 500 x 500 [mm]). Complete system including 2-chamber spray tunnel (degreasing/phosphating/rinsing), flash-off oven, mobile powder spray booth, curing oven (max. 220°C), cardan chain conveyor, and PLC control. New system / project proposal – special dimensions, heating types, layouts, etc. can be individually adapted to customer requirements.

System concept & customer-specific customization:

Semi-automatic powder coating system in batch mode for the efficient coating of steel parts. The system combines a compact footprint with high throughput and is ideal for small to medium-sized series components. The pre-treatment process is automated in batch mode, and the coating is applied manually.

Note on design:

The dimensions, assemblies, and heating types listed below correspond to the indicative offer presented. All components (e.g., useful lengths, booth dimensions, chain path, gas instead of electric heating) can be fully customized to your specific component dimensions, space requirements, and process requirements.
