Bath analysis – Coating thickness measurement through magnetic-inductive method, scanning electron microscopy/energy-dispersive microanalysis, test methods according to standard specifications.
Workpieces that have been coated using an acid process and which have a tensile strength of over 1000 N/mm² should be annealed because of the possibility of hydrogen embrittlement.
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.
Black oxidation of steel and iron as per DIN 50938 with methods groups A and B, and black colouration of stainless steel
Black oxidation of steel and iron as per DIN 50938 with methods groups A, B and C (C is 3-bath black oxidation)
Zinc phosphating and manganese phosphating as per DIN EN 12476
