Automatic Hardware Painting Line for Dipping Packaged Frames on Carbon Steel Structural Parts Liquid Paint Line

Structural Steel Liquid Painting Line with Automated Material Handling

Designed for Heavy Structural Components

This liquid painting production line is specifically engineered for carbon steel structural parts, providing reliable coating performance, high operational efficiency, and flexible process configuration. The system supports immersion coating technology and is suitable for a wide range of medium and large fabricated steel components used in construction, machinery, transportation, and industrial equipment manufacturing.

To accommodate different production requirements, the line can be customized according to workpiece dimensions, coating specifications, throughput targets, and factory layout conditions.

Flexible Coating Process

The system utilizes an inclined immersion coating method that allows coating material to fully contact the workpiece surface, ensuring excellent penetration and uniform film formation even on complex structures.

Coating Method

• Inclined basket immersion coating

• Full-surface liquid paint coverage

• Suitable for complex and welded steel structures

Efficient Material Handling System

The production line is equipped with a Power & Free overhead conveyor system, enabling flexible workpiece transportation and process accumulation.

Handling Features

• Power & Free conveyor technology

• Independent carrier movement and accumulation

• Forklift-assisted loading and unloading

• Stable transport for heavy-duty components

• Flexible production scheduling and buffering

Operating Capacity

• Maximum carrier load: up to 2,000 kg

• Adjustable conveyor speed: 0.5–3.0 m/min

• Custom-designed dipping tank dimensions available

Typical Process Flow

Forklift Loading → Immersion Coating → Paint Draining → Drying Oven → Natural Cooling → Forklift Unloading

Standard Processing Parameters

Process parameters can be adjusted according to coating material characteristics and product requirements.

Advantages

• Uniform Coating Coverage

The immersion coating process allows complete paint contact with all exposed surfaces, helping achieve consistent film thickness and reliable protection across the entire workpiece.

• Improved Corrosion Protection

A continuous and evenly distributed coating layer enhances resistance to corrosion, moisture, and harsh environmental conditions, extending product service life.

• Higher Production Efficiency

The accumulation conveyor system and automated material handling arrangement reduce manual intervention and improve production throughput.

• Lower Operating Costs

Optimized paint utilization and energy-efficient drying equipment help minimize material consumption and reduce overall operating expenses.

• Consistent Finish Quality

Advanced process control and carefully engineered production stages ensure stable coating quality, excellent appearance, and repeatable production results.

• Adaptable System Design

The line can be configured to accommodate different product sizes, coating processes, and production capacities, making it suitable for a wide range of industrial applications.
