Conveyor System Supported Powder Coating Line for Aluminum Profiles and Hardware Spraying Equipment

This powder coating production line is purpose-engineered for aluminum profiles in a wide range of lengths, shapes, and cross-sections, offering exceptional flexibility and consistent finishing quality. The system incorporates an overhead conveyor for stable and efficient part transport, while manual loading and unloading ensure safe handling of complex, delicate, or custom-shaped components.

Each of our powder coating lines is custom-designed according to the client’s product requirements, production capacity, layout constraints, and process specifications. Whether you need a standard configuration or a fully engineered solution, we guarantee a system precisely matched to your operational needs and performance targets.

Powder Coating Line Process Overview

1. Surface Preparation

The process begins with thorough cleaning and degreasing of the aluminum profiles. This step removes oils, dust, and contaminants, ensuring strong powder adhesion and preventing coating defects.

2. Pre-Treatment

After cleaning, the profiles undergo pre-treatment to enhance adhesion and corrosion resistance. Depending on requirements, this may include chemical cleaning, phosphating, or chromate conversion coating. These treatments optimize surface condition and improve coating performance.

3. Drying

Profiles are then conveyed through a drying oven to remove residual moisture. A fully dried surface is essential for uniform powder deposition and long-term coating durability.

4. Powder Application

Electrostatically charged powder particles are sprayed onto the grounded aluminum surfaces using specialized powder guns. This ensures even distribution and uniform coverage across all profile surfaces, including corners and complex geometries.

5. Curing

Coated profiles enter a curing oven, where controlled heating melts and cross-links the powder particles. This forms a hardened and continuous film with excellent mechanical strength and chemical resistance.

6. Cooling

After curing, the products are cooled to stabilize the coating film. Proper cooling helps maintain gloss, color consistency, and overall surface quality.

7. Quality Inspection

A final inspection verifies coating thickness, adhesion strength, visual appearance, and overall finish quality. Only products that meet the required specifications proceed to packing or further processing.
