Automatic Powder Coating Line for Metal Shelves
Customized Powder Coating System for Long-Length Shelf Components
This automatic powder coating production line is specially designed for coating metal shelves and similar long-length fabricated components. The system is configured with 13.5-meter-long hangers, providing sufficient loading space for large shelf structures while maintaining stable transportation throughout the coating process.
The spray booth is manufactured from high-quality PP (polypropylene) material, offering excellent chemical resistance, corrosion protection, and long-term durability. The coating system combines automatic electrostatic powder spraying with supplementary manual coating, ensuring efficient production while achieving complete coverage on complex shelf structures.
The production line adopts a power & free overhead conveyor system, allowing flexible workpiece movement between different process sections. Manual loading and unloading provide additional adaptability for various shelf designs and product specifications.

Powder Coating Process Flow
1. Surface Preparation
Before powder coating, the shelf components undergo surface preparation to remove:
Oil and grease
Dust and contaminants
Manufacturing residues
A properly prepared surface ensures strong adhesion and improves coating durability.
2. Pre-Treatment
After cleaning, the workpieces undergo pretreatment to enhance coating performance.
Typical processes include:
Chemical cleaning
Phosphating
Conversion coating treatment
Pretreatment improves:
Powder coating adhesion
Corrosion resistance
Surface stability
The exact process can be adjusted according to product material and performance requirements.
3. Drying
After pretreatment, the shelf components pass through a drying section to remove moisture.
Complete drying helps achieve:
Uniform powder adhesion
Stable coating quality
Reduced coating defects
4. Electrostatic Powder Coating Application
The dried workpieces enter the PP spray booth, where electrostatic spray guns apply charged powder particles onto the grounded metal surfaces.
The coating process provides:
Uniform powder distribution
High transfer efficiency
Stable coating thickness
Reduced powder consumption
Automatic spraying handles large-area coating, while manual touch-up ensures complete coverage of complex sections.
5. Powder Curing
After powder application, the coated shelves enter the curing oven.
During curing:
Powder particles melt and flow into a continuous coating film
Chemical cross-linking forms a durable protective layer
The finished coating provides:
Excellent corrosion resistance
Good impact resistance
Long-term surface protection
Attractive appearance
6. Cooling
After curing, the coated shelves are cooled before inspection.
The cooling process helps:
Stabilize the coating film
Maintain surface quality
Prepare products for further handling
7. Quality Inspection
Finished products undergo quality inspection, including:
Coating thickness measurement
Surface appearance checking
Adhesion testing
Overall coating quality evaluation
This ensures each coated shelf meets the required technical and visual standards.
