About Thommen Maschinenbau
Thommen Maschinenbau AG is a Swiss contract manufacturer for medium to large-scale machining of mechanical engineering components, headquartered in Rümlingen, Basel-Landschaft. Founded in 1946 in the village smithy of Buckten, the company offers CNC and conventional turning up to 8,000 mm between centers and 1,500 mm through-hole, as well as CNC and conventional milling including 5-axis machining. In addition, the company has a metalworking shop with welding processes (MIG/MAG, WIG/TIG, electrode) for complex components and welded constructions up to 15,000 kg. Further services include keyway slotting, planing, edge bending, shearing, flame cutting, painting, material procurement, design of special superstructures, as well as apparatus and machine engineering through to production outsourcing. Components are manufactured in steel, stainless steel, aluminium, cast materials, brass, copper and nickel alloys, among others, for plant engineering, the chemical industry, mechanical and apparatus engineering, military technology and aerospace. Contract and business languages are German, English and French.
