| Degreasing | In this step, a cleaning solution is sprayed onto the surface of the workpiece to remove any grease, oil, or contaminants that may be present. Degreasing is essential to ensure proper coating adhesion. |
| Phosphating | Phosphating is a chemical pretreatment process where a phosphate solution is sprayed onto the workpiece's surface. It creates a thin, adherent phosphate coating that improves the coating's adhesion and corrosion resistance. |
| Rinsing | After each pretreatment stage, the workpiece is typically rinsed with water to remove any remaining cleaning or pretreatment chemicals. |
| Surface Conditioning | Some pretreatment systems may include a surface conditioning step, where the workpiece is exposed to abrasive media to create a roughened surface. This helps improve coating adhesion, especially for certain materials. |
| Drying | Before the actual coating process, the workpiece is often dried to ensure a clean and moisture-free surface, which is vital for a successful coating application. |
