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