Professional Customized Iron Electric Control Cabinet Powder Coating Line with

Customized Iron Electric Control Cabinet Electrostatic Powder Coating Line with Lift

Overview

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.

Production Line Workflow

1. Hanger Stop & Elevator Loading

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.

2. Pre-Spray Surface Treatment

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.

3. Moisture Drying Section

After pre-treatment, the workpieces enter a drying area where residual moisture is fully evaporated, ensuring dry, contaminant-free surfaces before powder application.

4. Automatic Spraying Room

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.

5. Manual Spray Booth

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.

6. Powder Curing Section

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.

7. Natural Cooling Zone

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.

8. Elevator Unloading & Product Collection

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.
