PVD/CVD coating

Increasing cleanliness requirements and consistent cleaning results are common demands for the production of tools. Residue-free, wettable surfaces for metal substrates (e.g. tools, door handles) and plastics (e.g. fittings) are prerequisites for a successful coating process.

UCM offers optimized solutions, ranging from cleaning during processing to final cleaning before PVD/CVD coating. With its wide range of cleaning equipment ranging from aqueous to solvent-based, single-stage to multi-stage systems, UCM always offers the best solution for all cleaning processes in the production chain.
