About DEMA Metallspritzwerk iCoat AG
DEMA Metallspritzwerk iCoat AG in Schinznach-Dorf is a Swiss provider of thermal coating and industrial surface technology. The company coats new parts and components in repair and maintenance using plasma, HVOF, arc, wire flame and powder flame spraying processes. Core services are wear protection, corrosion protection and dimensional restoration of machine components. The offering is complemented by corundum blasting as pre-treatment as well as mechanical pre- and post-machining, including grinding on a 3-axis CNC grinding machine for parts up to 700 mm in diameter and 3000 mm in length. Customers come from industries such as hydropower, rail, energy, mechanical engineering, pump and valve technology, and hydraulics. Since 2022, DEMA has been the only company in Switzerland with the rail certification DIN 27201-10 for thermal coating of safety-relevant components of railway vehicles. In 2024, the company was acquired by Schenker Hydraulik AG and is part of the Schenker corporate group.
