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, while 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 varieties 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 blowing agents.
We have a blowing agent to suit your needs regardless of the application or the physical characteristics of the component.
Blasting is a pre-treatment process that can be equated with other mechanical pre-treatments such as grinding, brushing and polishing.
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.
HAI can blow glass profiles up to 8 meters in a continuous plant and offers economically advantageous glass blowing in fully automatic plants.
