Carbon Steel Sheet Powder Coating Line Automatic With Robot Polish Equipment

Powder Coating Production Line for Carbon Steel Sheets

This powder coating production line is designed to coat carbon steel sheets of various sizes and shapes, ensuring a safe and high-quality finish. The spray booth is constructed from PVC material, offering excellent durability and chemical resistance. The spraying process integrates automatic gun spraying with supplementary manual coating, allowing for precise application even on complex geometries.

Key Features:

• Pre-Treatment: Utilizes a skid ground conveyor system for efficient pre-treatment processes.

• Powder Spraying: Employs an overhead conveyor system that operates at a constant speed, ensuring consistent coating quality and throughput.

This setup guarantees optimal preparation and coating of carbon steel sheets, combining automation with manual flexibility to meet diverse production needs while maintaining safety standards and finish quality.

Production Line Workflow:

1. Welding Area Loading: A manipulator loads the cabinet body and door panel onto two separate stations.
2. Metal Grinding: A robot polishes the weld seams of the cabinet body.
3. The weld seams of the door panel are manually polished, followed by manual polishing of the overall surface to ensure smoothness.
4. Phosphating Solution Application: The workpieces are wiped with a phosphating solution to prepare the surface for coating.
5. Moisture Drying: Workpieces undergo drying at 40-50°C to remove any residual moisture.
6. Manual Putty Scraping: Technicians apply putty manually to fill in imperfections.
7. Putty Drying: The applied putty is dried at 40-50°C to ensure it sets properly.
8. Manual Putty Grinding: After drying, the putty is manually ground to achieve a smooth finish.
9. Workpiece Accumulation: Approximately 100 sets of workpieces are accumulated before moving to the next stage.
10. Mechanical Loading Transfer: Accumulated workpieces are transferred to mechanical loading for further processing.
11. Dust Blowing: Electrostatic dust guns are used for manual dust blowing to clean the surfaces.
12. Coating Application: Automatic spraying combined with manual spraying ensures comprehensive coverage.
13. Powder Solidification: Coated parts are cured at 200°C for 18 minutes to solidify the powder coating.
14. Air Cooling: After curing, the parts undergo air cooling to stabilize the coating.
15. Manual Installation of Casters: Casters are manually installed on the completed cabinets.
16. Human-Machine Assisted Lowering: With human-machine assistance, the finished parts are lowered onto AGV (Automated Guided Vehicle) carts for transport to the next destination.
