Anodizing
The revolution of metal surface treatment, anodizing technology, for your products with a strong protective coat. AFI Industrial Co., Ltd. provides superior surface treatment solutions for aluminum, magnesium, titanium and other metal materials using advanced anodizing processes.
Anodizing Process
Anodizing is a metal surface treatment technique that forms an oxide film on the surface of a metal by electrochemical oxidation. This process is usually carried out in an electrolyte solution, with a metal or alloy acting as the anode, on which an oxide film is formed by the action of an impressed current. Anodizing technology is widely used in aluminum alloy, magnesium, titanium, and other metals, among which sulfuric acid anodized is the most common treatment method
Rinse
Clean impurities such as oil and dust on the metal surface to ensure that the surface is clean to ensure the quality of the anodized effect.
Acid pickling
The metal is soaked in an acidic solution for pickling treatment to remove the oxide, oxide, etc., on the surface of the metal to improve the anodic oxidation effect.
Anodizing
Select the appropriate electrolyte, and DC power supply, control the electrolytic time, and obtain the required thickness of the oxide film.
Put Colour On
The coloring of the anodic oxide film can be divided into electrolytic and chemical coloring, by coloring to obtain the customer's required color.
Hole Sealing
The anodized or colored aluminum plate is put into the sealing solution to seal the micro holes in the anodized layer, improving its corrosion resistance and sealing performance.
Custom Anodizing Service
AFI Industrial Co., Ltd. provides anodizing services to its customers. We use advanced anodizing technology to provide customized anodize solutions and can perform specified anodizing services according to customers' specific color plate requirements to meet the quality control acceptance standards of anodized processes. Our anodizing services are widely used in the construction, automotive, aerospace, electronics, and consumer goods industries to meet the quality needs of our customers.
About Anodizing
Before anodizing, the surface of the metal is prone to scratches and rust, and the color is only the monotonous original color of the metal. After anodizing, the hardness of the metal increases, it is less prone to corrosion, and can be dyed in various colors.
Preanodize
Post-anodized
Anodizing Equipment
AFI Industrial Co., Ltd. has a comprehensive range of anodizing equipment, which is a key equipment used for metal surface treatment by forming a dense oxide film on the surface of the metal by electrochemical methods, thereby improving the corrosion resistance, wear resistance, and decoration of the metal, including but not limited to the following equipment:
Automatic Production Line
We have automatic production lines specifically for large-scale anodizing of materials such as aluminum, magnesium and titanium, which can achieve fully automatic operation from pre-treatment to post-anodizing treatment, quickly and in large quantities meeting the product demands of customers.
Ultrasonic Cleaning and Drying Equipment
Ultrasonic cleaning utilizes the tiny bubbles generated by high-frequency vibration to efficiently remove oil stains, dust, oxide layers or other contaminants from complex structures, micro-pores and crevices. After cleaning, the drying equipment needs to thoroughly dry the residual moisture or chemical reagents on the surface of the workpiece.
Anodizing Materials
Aluminum and aluminum alloys are the most suitable materials for anodizing. They are naturally prone to oxidation, and anodizing can form a thicker and harder oxide layer, which is widely used in mobile phones, notebook casings, automotive parts and some household electrical appliances.
Magnesium and magnesium alloys, due to their high reactivity during anodizing, require micro-arc oxidation before conventional anodizing. They are also frequently used in aerospace, electronics and electrical fields.
After anodizing titanium and titanium alloys, the oxide film can show rainbow colors, has good biocompatibility, and is often used in medical equipment.
Zinc and zinc alloys can also undergo anodizing, but the effect is not very good and it is usually only used for temporary rust prevention.
Our company can customize the anodizing effect for you based on the specific requirements of your materials, meeting the quality requirements of your products.
Anodizing Test Equipment
The quality testing of the anodize process involves many aspects of the testing equipment, AFI Industrial Co., Ltd. through the testing equipment to ensure the quality and stability of the anodize process, through the accurate measurement of oxide film thickness, wear resistance, density, and other key parameters to meet the quality requirements of the product.

Frequent Asked Questions
Anodic oxidation is a process that generates an oxide film on the surface of metals through electrochemical treatment. It is mainly used to enhance the corrosion resistance, wear resistance, insulation of products or change their appearance color.
The time required for anodizing depends on the size, structure, thickness of the oxide layer and the type of anodizing agent used for metal products. Our company usually completes the anodizing of samples and small batches within one day. The anodizing time for large quantities is 2 to 3 days.
Both common anodizing and hard anodizing can play a role in corrosion resistance. Hard anodizing has higher hardness and wear resistance than ordinary anodizing. Therefore, hard anodizing is used for highly wear-resistant components such as engine cylinders, pistons, bearings, and gears. In addition, the hard anode also has excellent insulation performance and is suitable for electronic components that require good insulation. Ordinary anodes can be made in various colors, and thus are often used in architectural decoration, furniture hardware, car wheels, etc. Our company can select different anodizing methods according to the functions that customers need to achieve.
From the preparation work before oxidation to the post-oxidation treatment, we will follow industry standards and strictly control the quality of every link. For the finished products, we will inspect the appearance, film thickness, hardness, and corrosion resistance of the anodized products through visual inspection, instrument inspection, and salt spray test to ensure that every product received by the customer is qualified.
