Robot painting for plastic exterior parts
Bumpers, spoilers and grilles up to 1,900 × 800 × 700 mm are coated by five GR6150-2900 robots — one primer, two base, two clear — tracking a conveyor at 0.3–2.5 m/min. Film builds are 8–12 µm primer, 15–30 µm base and 30–40 µm clear, with 2-colour primer change, 12-colour base change including pearl, and externally mixed 2K clear.
The numbers behind this configuration
| Parts | Up to 1,900 × 800 × 700 mm on skids at 2,800 mm pitch |
|---|---|
| Robots | 5 × CMA GR6150-2900 with conveyor tracking |
| Film build | Primer 8–12 µm · base 15–30 µm · clear 30–40 µm |
| Colour change | Primer 2 colours 6-way · base 12 colours 15-way · clear 2K hardener valves |
| Conveyor | 0.3–2.5 m/min (0.8 for pearl white), 2.69 min per skid |
| Guns | DeVilbiss AGMD-Pro 1.4 mm, 6 cc servo gear pumps |
Figures come from the project records behind the linked projects below, not from a brochure. Your line will differ — these are what we actually built or engineered.
What we supply
- Survey of the existing line before bidding — booth dimensions, airflow, skid geometry
- Robot positions and reach simulation against the real part mix
- Colour-change stack sized to the actual change frequency, not the colour count
- 2K clear coat mixing and flush arrangement
- Safety PLC, remote I/O, encoder tracking and muting
What this application taught us
An existing-line retrofit is surveyed on site before bidding. PDF drawings with no CAD and no air-balance diagram left a booth-widening question unresolved to the end of one proposal.
What we need from you
- Part drawings or dimensioned photographs, including the deepest recess to be coated or the full weld list.
- The paint or process specification: 1K or 2K, solvent or waterborne, powder, adhesive or wire, with the required film build or weld size.
- The required output — parts or jobs per hour — and the shift pattern.
- Booth or cell dimensions, the conveyor or hanger arrangement, and the hazardous-area classification your safety engineer has assigned.
