The headquarters of the TELSONIC Group is located in Bronschhofen, Switzerland. More than 250 highly-qualified employees, individual affiliates in Germany, Serbia, England, America, China and specialized distributors support the application and process development of our customers in the application of our ultrasonic technology. TELSONIC supports the research and basic development for the usage of ultrasonic technology through its activities at universities in Switzerland and in Germany. Quality is important to us. Ultrasonic is nearly omnipresent in the initial stages of production for articles made of plastic and metal or during their final assembly and thus, TELSONIC is an absolute specialist in regards to industrial ultrasonic technology. 


We are certified according to ISO 9001 (SQS) and apply the principles of lean production. Our technical documentations, or their translations, are developed in accordance with ISO/DIS 17100 and support our globally active customers in the qualified application of our ultrasonic systems. Countless patents in the area of the industrial application of ultrasonic prove our innovative power, since 1966.
