About Jean Gallay SA
Jean Gallay SA is a manufacturing service provider specialized in aerospace and energy technology, based in Plan-les-Ouates near Geneva. The company machines, forms, joins and heat-treats components made from superalloys for extreme operating conditions. More than 30 manufacturing and inspection processes are combined under one roof, including CNC machining, electrical discharge machining (EDM), laser beam welding with fiber and YAG lasers, brazing, plasma coating and heat treatment. The portfolio is complemented by inspection services such as 3D measurement with GOM, penetrant testing, X-ray inspection and flow measurement, as well as an in-house laboratory, tool design, build-to-print manufacturing and co-engineering. The components are used in civil and military aircraft engines (including CFM56, Leap, GE90, M88), helicopter engines (including Arriel, Makila) and industrial gas turbines (including SGT5/6-8000H, LMS100). More than 200 customer qualifications demonstrate approval by international engine and turbine manufacturers.
