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.
The BUMAX DX 129 (Duplex stainless steel) offers very high tensile strengths of min. 1,200 MPa and excellent fatigue resistance properties. It deals successfully with the extreme forces during the ultrasonic welding process, such as 20,000 vibrations per second.
The high fatigue strength that BUMAX screws offer is crucial to their ability to withstand a high number of cycles without fracture. All BUMAX bolts are made with the highest quality European steel, and its advanced manufacturing processes result in the further enhancement of the material’s fatigue resistance properties.
The high-quality raw materials BUMAX uses guarantee excellent fatigue strength. BUMAX also uses rolled threads rather than cut threads, which further increases fatigue resistance.
