We can rapidly and reliably carry out the treatment processes black oxidation (ferrous steel and casts), phosphating (zinc and manganese phosphating) and stainless-steel colouring in our computer-controlled fully automated contract treatment plants.
A manually-charged treatment plant is also available for special processes such as the colouring of brass, copper and zinc die-cast components.
You can profit from our knowledge and experience as a manufacturer of chemicals and plants for chemical surface treatments with regards to surface results.
