Micro Arc Oxidation Aluminum Roller

High-Performance Ceramic-Coated Aluminum Roller for Demanding Industrial Environments

The MAO Aluminum Roller leverages advanced micro-arc oxidation (MAO) technology to deliver a robust, lightweight solution for industries requiring exceptional durability, corrosion resistance, and thermal stability. Engineered to withstand harsh operational conditions, this roller combines aerospace-grade aluminum with a dense ceramic oxide coating, ensuring long-term reliability in critical applications. Below, we outline its technical advantages, customizable features, and industry-specific applications.

Advantages
Outstanding Corrosion Resistance
The MAO process forms a uniform ceramic oxide layer on the aluminum surface, providing protection against moisture, chemicals, and saltwater. This makes the roller ideal for marine engineering, chemical processing, and food production environments where exposure to corrosive agents is common.

Enhanced Wear and Abrasion Resistance
With a surface hardness exceeding 1,500 HV (Vickers hardness), the ceramic coating significantly reduces wear caused by friction, abrasive materials, or high-stress operations. This extends the roller’s service life in applications such as metal stamping, mining, or heavy machinery.

Key Features
Versatile Configurations
The roller is available in multiple designs to suit diverse machinery requirements:

Flat Tube Type: Ensures uniform pressure distribution for precision tasks like laminating or coating.
Without Shaft Type: Streamlines integration into compact systems with space limitations.
Through Shaft Type: Supports continuous rotational motion in high-torque applications.
Shaft Type: Compatible with standard industrial setups for enhanced load-bearing capacity.
Customizable Surface Treatments
Tailor the roller’s surface to optimize performance:

Polished Finish: Reduces friction for smooth material release in printing or film processing.
Textured Finish: Enhances grip in conveying systems handling slippery or irregular materials.
Hybrid Coatings: Optional layers (e.g., PTFE) for anti-sticking or non-conductive properties.

Precision Manufacturing
Each roller undergoes rigorous quality control to ensure dimensional accuracy, balance, and compliance with international standards such as ISO 9001.

Automotive Manufacturing
The roller is integral to robotic welding lines and electric vehicle (EV) battery assembly, where corrosion resistance and thermal stability ensure consistent performance in high-temperature environments.

Aerospace & Defense
Its lightweight design and resistance to temperatures make it suitable for composite layup tools and precision machining of aircraft components.

Food & Beverage Processing
The non-toxic, easy-to-clean ceramic surface meets stringent hygienic standards, ideal for handling raw ingredients or packaging in wet or chemically aggressive settings.

Renewable Energy
Used in solar panel laminating systems and wind turbine blade production, where durability and precision are critical for long-term operational efficiency.

Oil & Gas
Resistant to harsh chemicals and abrasion, the roller supports drilling equipment and pipeline maintenance in corrosive environments.

Case Study: Enhancing Efficiency in Metal Stamping
A automotive parts manufacturer replaced traditional steel rollers with MAO-coated aluminum rollers in their metal stamping line. Challenges included frequent wear from abrasive materials and high maintenance costs.
