This article focuses on the "painting process" itself, detailing the complete chain involved in robotic painting:
- Pretreatment: Cleaning, phosphating for a good substrate
- Paint Prep & Delivery: Mixing, viscosity/temperature control, stable delivery
- Atomization & Formation: Principles of air, air-assisted airless, and high-speed rotary (bell) atomization
- Electrostatic Attraction: Principles, high-voltage generator selection, and safety
- Spray Path & Parameters: Relationship of distance, speed, overlap to film thickness
- Flash-off & Curing: IR, hot air, UV curing methods
The aim is to understand how equipment serves the process.
