Ball burnishing is a particularly effective pre-treatment of aluminium, which is used when there are special requirements for the aluminum's glossiness.
Ball burnishing is used to give aluminum blanks a smoother, more even and glossier surface. Even when processing large quantities of aluminum blanks, the ball burnishing ensures a nice and uniform appearance.
Ball burnishing can blur or remove minor scratches and similar surface defects.
Depending on the surface requirements, different ball types are used. Stainless satellites are typically used with the addition of a polar compound.
Ball burnishing of items takes place in rotating drums, where the items are mechanically polished with small stainless steel balls or satellites with the addition of sanding paste or a compound powder.
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.
