About LST247
LST Laser & Schalttechnik GmbH & Co. KG (LST247) is an owner-managed full-service system supplier for sheet metal parts and sheet metal assemblies based in Beuren at the foot of the Swabian Alb. Founded in 1994 by Hans-Dieter Gugel, the family business, now in its second generation, manufactures custom sheet metal parts to drawing as a contract manufacturer – from laser blanks and bent parts to complex, ready-to-assemble welded assemblies. The process chain includes laser cutting (2D and 3D, 6-axis), bending and folding, mechanical machining, welding as a certified welding specialist shop according to ISO 3834-2, and surface treatment; finishing, heat treatment and further machining are carried out via a long-standing partner network. Materials processed include quality steel sheet up to 25 mm, stainless steel up to 20 mm and aluminium up to 10 mm in more than 35 grades, stocked in the fully automatic STOPA sheet metal warehouse with over 700 tonnes of inventory. Customers come from mechanical engineering, plant construction, automotive, automation technology, medical technology, electrical engineering and other industries – from batch size 1 via prototypes and small series through to large series with framework agreements, optionally with 24-hour express production and online quoting.
