Learn more about interior anodizing

Anodizing is an effective treatment that is used when there are special requirements for the aluminum's corrosion resistance both externally and internally. 

Further information

Internal anodizing, a specific anodizing process where there is a special focus on treating aluminum blanks from the inside. Like a normal anodizing process, the purpose is to protect aluminum from corrosion and wear. Internal anodizing is particularly good for items where there are special requirements to be able to withstand wear, liquids or the like from the inside.  

Internal anodizing takes place in one of our many process vessels with the aim of building an oxide layer which protects aluminum against corrosion, mechanical impact and penetration of foreign elements. 
The process is used at the same time as normal anodizing of the workpiece.

Clariant

In recent years, aluminum has become a widely used material in everyday life. Both for interior architecture and for more decorative purposes.

The colors go through a constant quality control, which ensures uniform coloring and high quality. However, we would like to point out that color differences may occur depending on whether it is a matter of coloring cast items, plates and profiles.

Indoor coloring

Today, anodized aluminum is used more and more often for architectural purposes. Buildings are more often constructed in aluminium, which is perfect for this purpose. For example, the buildings' facades are naturally anodised or colored aluminium, as the metal is light, requires minimal maintenance and fits into most environments.

Blowing is an effective mechanical pre-treatment that is used when there are special requirements for the aluminum's structure or hardness. Blasting leaves a nice, uniform and matte surface at the same time, the treatment can to a certain extent remedy machining surfaces, grinding marks, tensile and heat streaks, which are visible on the raw material. This is due to changes in the material structure, which achieves the more uniform surface and with a matte appearance before further processing.​

HAI offers several different blowing media with different roughness in the structure to give the uniform surface a broken structure.

We have different variants of blowing agents, where depending on the desired result, you can choose between; glass beads, precious corundum, stainless steel balls, stainless steel grit and mixed blasting agent.

We have a blowing agent that suits your needs regardless of the application or the physical characteristics of the component.

The treatment takes place in a closed cabin, where our operators blow fine grains of glass against the aluminum blanks. This achieves a uniform surface and a nice finish on the entire item.​

Blowing is a pre-treatment process that can be equated with other mechanical pre-treatments such as grinding, brushing and polishing.​

​​HAI can blow glass profiles up to 8 meters in a continuous plant and offers economically advantageous glass blowing in fully automatic plants.
