About Groupe TMA
Groupe TMA is a pure contract manufacturer for industrial metal cutting and metalworking, founded in France in 1984. The company operates exclusively as a subcontracting partner, supplying the most demanding heavy industry and industrial supply sectors with more than 400 customers. At five production sites in Molsheim (Alsace), Senones and Le Thillot (Vosges), Chelles (Île-de-France) and Toussieu (Rhône-Alpes), 150 employees transform around 12,000 tonnes of metal per year. The range of processes includes laser cutting (0.5–25 mm), waterjet cutting (0.5–280 mm), flame cutting of carbon steel up to 300 mm thickness, plasma cutting (0.5–45 mm), punching, press punching, deep drawing, bending, sheet metal working and machining by turning, milling and drilling; complemented by welding, deburring, finishing and engraving. Materials processed include steel, carbon steel, stainless steel, aluminium, copper, brass and plastics. The service offering is rounded out by a planning and methods office, a raw material inventory and logistics services; an online quotation tool is available.
