Product Description and Features

The mobile flow channel conductive oxidation line used in industry is an automated production equipment specifically designed for conducting conductive oxidation (also known as chemical conductive oxidation) treatment on aluminum alloy parts. It is named for its unique operating method and is widely applied in electronics, communications, aerospace, and other fields.
Below are its detailed features and specifications:

I. Core Concepts and Working Principles

1. Core Concept:
   

   "Mobile flow channel" refers to the production process where workpieces (aluminum alloy parts undergoing treatment) are suspended on a continuously moving conveyor chain system. They sequentially pass through various treatment tanks to complete all processing steps. The entire production line resembles a flowing river, with workpieces advancing along the "water flow" (conveyor chain), hence the name.
   
   

2. Working Principle:
   Workpieces are secured to the conveyor chain via fixtures. The chain moves workpieces sequentially through the following typical stations at a preset speed:
   Loading → Degreasing → Water Rinse → Alkaline Etching → Water Rinse → Brightening → Water Rinse → Electroless Plating → Water Rinse → Hot Water Sealing → Drying → Unloading

The entire process is fully or semi-automated, eliminating the need for manual handling of workpieces in and out of the tank, thereby achieving continuous production.

II. Key Features

1. High efficiency and continuous production

Assembly line operation: Workpieces continuously enter and exit the production line, eliminating waiting times associated with single-station processing and achieving extremely high production efficiency.
Cycled production: Production speed is determined by the conveyor chain's velocity, enabling precise capacity calculation and making it highly suitable for large-volume order production.

2. Exceptional stability and consistency

Process parameters are stable: Soak time, chemical concentration, and temperature in each treatment tank are strictly controlled by an automated system, ensuring consistent oxide film quality across every batch and even each individual workpiece.
Minimized human interference: Automated operation significantly reduces quality fluctuations caused by human error, such as inaccurate timing control or handling impacts.

3. Highly automated, saving manpower

From feeding to discharge, the entire process requires minimal manual intervention, with operators only needed at the loading and unloading stations. This significantly reduces labor intensity and labor costs.

4. Optimize spatial layout

The production line adopts a linear or U-shaped layout, featuring a compact structure with a relatively small footprint. Its rational planning ensures smooth material flow.

5. Excellent process compatibility and scalability

The number and functions of treatment tanks can be flexibly increased, decreased, or adjusted based on specific product requirements and oxidation processes (e.g., adding post-treatment stations such as passivation or spraying).

6. Improving the Work Environment and Safety

Automated systems isolate operators from chemicals, reducing the risk of direct contact.
Production lines are typically equipped with comprehensive ventilation systems and wastewater/exhaust treatment facilities, enhancing environmental performance.

III. Special Notes on Conductive Oxidation Process in the Treatment Line

Conductive oxidation performed on mobile flow lines has specific process requirements:
Film characteristics: The generated oxide film is extremely thin (typically 0.5–4 microns), colorless or iridescent, does not alter workpiece dimensions, and exhibits excellent conductivity with moderate corrosion resistance.
Processing temperature: Typically conducted at room or moderate temperatures, resulting in lower energy consumption.
Comparison with Anodizing: Conductive oxidation (chemical oxidation) requires significantly lower equipment investment and operational costs than anodizing (which necessitates electrical power and cooling). It offers faster processing speeds but yields coatings with lower hardness, wear resistance, and corrosion resistance compared to anodized films. Consequently, it is primarily used for electronic components requiring conductivity (e.g., enclosures, shielding covers, electrical connectors) and as a primer layer for painting.

IV. Typical Application Areas

Electronics and Electrical Industry: 5G communication enclosures, server chassis, shielding covers for network equipment, electronic components, etc.
Aerospace Sector: Aluminum alloy parts for aircraft interior and exterior components, requiring conductivity and corrosion resistance.
Precision Instruments and Meters: Aluminum housings and structural components for various instruments.
Automotive Industry: Housings for automotive electronic control units (ECUs), etc.
Industrial Mobile Conduit Conductive Anodizing Lines epitomize the pursuit of efficiency, quality, and automation in modern large-scale manufacturing. Integrating mature chemical oxidation processes with precision mechanical automation systems, they deliver an efficient and reliable surface treatment solution for aluminum alloy components—particularly those requiring electrical conductivity.
