About MS Ultrasonic
MS Ultraschall Technologie GmbH, headquartered in Spaichingen as the parent company of the MS Ultrasonic Technology Group, develops and manufactures ultrasonic welding machines for thermoplastics, films, textiles and nonwovens. The portfolio includes customer-specific special welding machines (MS sonxMAC), standard ultrasonic servo presses (MS sonxTOP), modular systems for packaging and nonwovens applications (MS sonxSYS) as well as in-house manufactured components such as generators, converters and sonotrodes (MS sonxCOM). More than 90 percent of value creation takes place in-house, including toolmaking with modern machine tools. The processes include ultrasonic welding, punching, riveting, cutting and embossing, infrared riveting, heat contact welding as well as gluing and assembly. Customer industries include automotive, packaging and food industry, textiles/nonwovens, medical technology, consumer goods and electrical components. Since 2024 the group has been part of the Schunk Group and operates production and TechCenter locations in Germany, the USA, Brazil, China, Italy and the Czech Republic.
