CHEMICAL SURFACE TREATMENT
When you visit us you'll be struck by the craftsmanship that is still behind many high tech products. Over the years of collaboration with SAAB we have built up a specialised skill set in masking and surface treating aluminium alloys in small series production runs.
The work is performed in accordance with the strict specifications required by the defence industry.
Our surface treatment is performed entirely manually. Being meticulous and working within millimeter precision when masking and treating is more important to us than quantity. Your contact in Alumbra will handle the entire job including inspection and packing of each part.
We can undertake masking as well as anodising and chromating of aluminium components. We also undertake passivation of stainless steel.
