Product Description

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.


Production Line Features

Automatic Spraying with Manual Touch-Up Capability

The powder coating section integrates automatic spray guns with manual finishing stations.

This hybrid spraying method provides:

  • Consistent coating thickness

  • Improved powder application efficiency

  • Complete coverage of corners and difficult areas

  • Flexible handling of different shelf designs

  • Enhanced surface finish quality

Automatic spraying ensures stable production performance, while manual coating allows operators to optimize areas requiring additional attention.

Long-Length Power & Free Conveyor System

The power & free overhead conveyor is designed for handling large shelf components with long hanging distances.

Key advantages include:

  • Suitable for 13.5-meter hanger length applications

  • Flexible carrier movement control

  • Efficient use of factory space

  • Stable transportation of large workpieces

  • Smooth connection between coating processes

The conveyor system can be customized according to product dimensions, production capacity, and factory layout.

Durable PP Powder Spray Booth

The spray booth is constructed from polypropylene material, providing:

  • Excellent chemical resistance

  • Good corrosion protection

  • Easy cleaning and maintenance

  • Long service life in coating environments

The booth design helps maintain a stable spraying environment and improves coating consistency.

Our engineering team develops customized coating solutions to improve:

  • Production efficiency

  • Coating quality

  • Equipment reliability

  • Long-term operational performance

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.
