Laser drilling
Hole diameters from 2 µm with µm precision.
Laser micro machining (structuring, ablation)
Surface machining of steel, titanium, Nitinol, plastics and glass.
Electrochemical machining (ECM/EWS)
Force- and stress-free cutting of precision metal components; since 2004 as an in-house system, EWS.
Mechanical series machining (machining)
Series production of metal components according to IATF 16949.
Laser powder deposition welding
Deposition welding for coating and repair of components.
Automated assembly
Force-displacement-monitored joining, screwdriving, riveting, crimping, clinching, dosing and potting.
Quality assurance
Metrology, optical inspection, leak and flow testing as well as marking (DMC, laser marking).
