I previously wrote an article titled "[Surface Treatment] Regarding Hydrophilicity, Hydrophobicity, and Water Repellency." The effects presented are widely used in surface treatment. For example, hydrophilicity focuses on whether water adheres well to the surface of a workpiece after cleaning. Poor hydrophilicity can affect subsequent treatments....
After anodizing, aluminum forms a hard, transparent film. However, the condition of the film after bending is not well understood. Therefore, a customer asked us to find out if there are any abnormalities on the surface of the anodized aluminum after bending.
Sealing treatment is the last and most important treatment in the anode treatment process. When the sealing effect is good, it can improve the corrosion resistance of the product. If the product is dyed, it has a blocking effect so that the dye will not flow out of the surface. The principle of sealing treatment is mainly to seal the...
The term "nickel-free sealing" has been around in the topic of anodizing treatment for a long time. It originated from the occurrence of allergies among consumers in South Korea many years ago when using mobile phones. It was verified that nickel metal was contained in the surface treatment process. Nickel is one of the common allergens that can...
In the pre-treatment of the anode treatment process, there is a process that is indispensable. We often hear people call this process "neutralization", "ash removal" or "film removal treatment". Here we collectively refer to it as "film removal". Except ".
Aluminum die-casting materials have the characteristics of adjustable material thickness, good precision, high yield and good productivity. Aluminum-copper-silicon alloy is widely used in the industry. However, the material contains a large amount of silicon, copper, release agents and other substances that affect surface treatment. In addition,...
If the purity of aluminum metal is greater than 99%, the material is pure aluminum (numbered 1000). In order to meet the requirements of strength, processability and corrosion resistance of various products, corresponding metal elements are added to the pure aluminum metal. , so that it can meet the set requirements. (See chart below)
There are three ways to shape aluminum castings, including sand molds, metal molds and precision casting. In order to meet the requirements of high castability and higher strength, silicon, copper, magnesium and other related elements will be added to the material to achieve aluminum casting materials that meet market demand.
