Product Description
Automated Powder Coating Line for Carbon Steel Sheets
This industrial powder coating production line is specifically engineered for carbon steel sheets of various sizes and shapes, delivering high-quality finishes with integrated robotic polishing and comprehensive automation.
Key System Features
- PVC spray booth construction for superior durability and chemical resistance
- Combined automatic gun spraying with manual coating for complex geometries
- Skid ground conveyor system for efficient pre-treatment processes
- Overhead conveyor system operating at constant speed for consistent coating quality
Production Workflow Process
- Welding Area Loading: Manipulator loads cabinet body and door panel onto separate stations
- Metal Grinding: Robot polishes weld seams of cabinet body
- Manual Polishing: Door panel weld seams and overall surface manually polished
- Phosphating Solution: Workpieces wiped with phosphating solution for surface preparation
- Moisture Drying: Drying at 40-50°C to remove residual moisture
- Manual Putty Application: Technicians apply putty to fill imperfections
- Putty Drying: Applied putty dried at 40-50°C for proper setting
- Putty Grinding: Manual grinding after drying for smooth finish
- Workpiece Accumulation: Approximately 100 sets accumulated before next stage
- Mechanical Loading Transfer: Workpieces transferred to mechanical loading
- Dust Blowing: Electrostatic dust guns used for manual surface cleaning
- Coating Application: Automatic spraying combined with manual spraying for comprehensive coverage
- Powder Solidification: Coated parts cured at 200°C for 18 minutes
- Air Cooling: Parts undergo air cooling to stabilize coating
- Caster Installation: Casters manually installed on completed cabinets
- Final Transfer: Human-machine assisted lowering onto AGV carts for transport
Powder Coating Line Technical Process
| Process Step | Technical Description |
|---|---|
| Surface Preparation | Initial cleaning, degreasing, and contaminant removal from aluminum profiles to ensure proper powder adhesion |
| Pre-Treatment | Chemical cleaning, phosphating, or chromate conversion coating to enhance adhesion and corrosion resistance |
| Drying | Moisture removal through drying ovens for optimal powder coating adhesion |
| Powder Coating Application | Electrostatically charged powder sprayed onto grounded profiles using powder coating guns for uniform coverage |
| Powder Curing | Thermal curing at elevated temperatures melts and flows powder particles, creating continuous coating film with chemical cross-linking |
| Cooling | Stabilization phase allowing coated profiles to cool, maintaining coating properties and appearance |
| Quality Inspection | Comprehensive checking of coating thickness, appearance, adhesion, and overall quality standards |
