2023-08-24
Swedish fastener manufacturer BUMAX has been selected to provide fasteners to be used in machines for ultrasonic metal welding. The client is Schunk Sonosystems, a global leading specialist in the field of ultrasonic metal welding.
German specialist machine maker Schunk Sonosystems has decided to use BUMAX DX 129 screws for all its ultrasonic welding flexure sonotrode products to further improve quality and reliability. The machines are mainly used in the automobile industry.
"Standard steel bolts simply cannot cope with the extreme pulling and bending forces of ultrasonic vibration, so we had to find a bolt that does,” said Stefan Mueller, Head of R&D at Schunk Sonosystems. “Of all the screws we tested, only BUMAX met all our needs. Not only are BUMAX consistent in how they perform and do not break, they last the lifetime of the sonotrode without problem, are not creating abrasion dust on the screw head and do not require rust protection.”

The BUMAX DX 129 (Duplex stainless steel) offers very high tensile strengths of minimum 1,200 MPa and excellent fatigue resistance properties. It deals successfully with extreme forces during the ultrasonic welding process, such as 20,000 vibrations per second.
