About MK Klassik
MK Klassik GmbH is a manufacturing partner specialized in high-frequency welding, headquartered in Haar near Munich (Gronsdorf). The company, with around 40 employees, processes technical and natural textiles, leather, artificial leather, plastics and foams – often with air- and water-tight joints that remain stable even under high pressure. Manufacturing methods include, in addition to high-frequency welding, waterjet and laser cutting, sewing, cutting, punching, deep drawing and 5-axis CNC milling; an in-house toolmaking operation enables custom tools for prototypes and series production. Fields of application include automotive (seat belt and release loops, convertible top compartments, seat development), acoustics (acoustically effective acoustic elements), medical technology (foldable curtains, radiation protection), construction protection (bellows systems for bridge bearings) and sports, including the in-house development FLAT JACK® for tire-friendly vehicle storage as well as avalanche airbags for worldwide distribution.
