This fully customized powder coating line is specially designed for the surface finishing of iron electric control cabinets. The system combines automatic and manual powder application, ensuring complete and uniform coating coverage on complex geometries. The production line integrates a PP (polypropylene) spray booth for superior corrosion resistance and environmental safety, along with a suspended chain hoist and lift system for smooth, ergonomic workpiece handling.
Workpieces are manually loaded onto the conveyor using an elevator-assisted system. The hangers stop at the designated station, allowing safe and efficient hanging operations.
The workpieces pass step by step through each pre-treatment stage—washing, rinsing, and surface conditioning—pausing at each station for complete and uniform cleaning. This ensures excellent coating adhesion.
After pre-treatment, the workpieces enter a drying area where residual moisture is fully evaporated, ensuring dry, contaminant-free surfaces before powder application.
At a controlled speed of 1.5 meters per minute, the workpieces travel continuously through the automatic spraying room. Multiple electrostatic spray guns apply powder coating evenly across all surfaces. Additional manual touch-up stations are available to ensure perfect coverage in complex or recessed areas.
Workpieces stop briefly in a manual spray booth for detailed hand coating. Operators can precisely apply powder to ensure consistent thickness and flawless finish quality.
The coated workpieces are accumulated and transferred into the curing oven, where controlled heat ensures complete powder fusion and cross-linking, forming a durable, high-performance coating layer.
After curing, the parts move into a natural cooling section, allowing the coating to stabilize and harden gradually without thermal stress, preserving the coating’s mechanical and aesthetic integrity.
The elevator descends again to assist in the manual unloading of finished products. The coated control cabinets are then prepared for inspection, assembly, or packaging.
Integrated Automation: Combines continuous automatic spraying with manual precision coating.
Corrosion-Resistant Booth: PP spray booth ensures long service life and easy maintenance.
Ergonomic Material Handling: Lift and chain hoist system reduce manual labor intensity.
Consistent Quality: Controlled process flow guarantees even coating and optimal curing results.
Flexible Design: Can be adapted to different cabinet sizes, coating types, and production capacities.
The Process of Powder Coating Line:
| 1. Surface Preparation: | The first step in the powder coating line is the surface preparation of the aluminum profiles. This stage is essential to ensure proper adhesion of the powder coating. Surface preparation may include cleaning, degreasing, and removing any contaminants from the aluminum surfaces. |
| 2. Pre-Treatment: | After surface preparation, the aluminum profiles undergo a pre-treatment process to enhance coating adhesion and corrosion resistance. Common pre-treatment methods include chemical cleaning, phosphating, or chromate conversion coating. The pre-treatment prepares the aluminum surface for better powder adhesion and improves coating performance. |
| 3. Drying: | Once the pre-treatment is completed, the aluminum profiles are passed through drying ovens to remove any remaining moisture from the surface. Dry aluminum surfaces are crucial for proper powder coating adhesion and finish. |
| 4. Powder Coating Application: | The dried aluminum profiles are then ready for powder coating application. The powder coating material is electrostatically charged and sprayed onto the aluminum profiles using powder coating guns. The positively charged powder particles are attracted to the grounded aluminum profiles, adhering to the surface uniformly. |
| 5. Powder Curing: | After powder coating application, the aluminum profiles are transferred to curing ovens. In the curing ovens, the powder coating undergoes a thermal curing process. The oven's heat causes the powder particles to melt and flow, creating a continuous, smooth coating film. The curing process also chemically cross-links the powder particles, ensuring a durable and hardened finish. |
| 6. Cooling: | Following the curing process, the coated aluminum profiles are allowed to cool down. This cooling phase stabilizes the coating and ensures it maintains its properties and appearance. |
| 7. Quality Inspection: | After cooling, the coated aluminum profiles undergo a thorough quality inspection. The inspection involves checking the coating thickness, appearance, adhesion, and overall quality to ensure it meets the specified standards. |
