Anodizing is an effective treatment that is used when there are special requirements for the aluminum's corrosion resistance on delicate items.
Deoxidation is a pre-treatment process which helps to clean the items. The second function of the process is to break down the oxide layer that naturally builds up on aluminum surfaces.
Chemical deoxidation is a process where only the natural oxide layer that sits on the surface of the aluminum is etched. Contrary to chemical pickling, a milder result is achieved both in terms of removing scratches and cleaning the surface.
Because deoxidation is so gentle, it leaves an almost untouched surface. Most often, it will appear with a very slightly matted surface.
This treatment is really good for more gentle subjects, such as e.g. machine parts, technical articles or decorative articles where you want to retain the original dimensions.
Deoxidation is often used in technical anodizing, where the workpieces are processed in excess. When the items are anodized, they fit in relation to the specified tolerances.
Purely decorative, deoxygen is used when you want as natural an expression as possible.
|E0||Degreasing and Deoxidation||A pre-treatment that only cleans and activates the surface. All scratches, marks and corrosion damage will remain visible.|
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.
