Spraytest Creation Methodology
You can use this short article as a guide for creating your own Spraytest according to recommended methodology.
Goals and Benefits
- Provide objective data on the differences in output between various rotors/applicators within the same cabin.
- Generate surface thickness maps.
- Recognize and solve problems efficiently.
- Optimize processes.
- Accelerate the implementation of new models and paints.
Pattern Program Development
Static Pattern Gun / Bell
- Position the robot arm in front of a flat surface with the applicator set at the production distance (typically 150-300 mm).
- Set timers for shaping air, paint flow, and needle opening as follows:
- Shaping Air: 2 seconds
- Shaping Air and Paint Flow: 1 second
- Place a foil in front of the applicator.

Dynamic Pattern Gun / Bell
- Position the robot arm in front of a flat surface with the applicator set at the production distance (typically 150-300mm).
- Place foil on the flat surface and set the trajectory to a straight line from left to right, covering the full width of the foil.

Adjustments for Material Sagging
- For static patterns, reduce the paint flow timer from 1 second.
- For dynamic patterns, either increase the velocity or decrease the paint flow.
