Ultrasonic Welders The substantial progress in ultrasonic welding technique We set a high value on easy handling, reliable welding results, quality assurance and reproducibility while advancing and optimizing the machine. A number of factors influence the quality of a weld seam. To reach a reproducible, sound weld result the thermoplastic synthetics must be chosen, considering its feedstock influences. The selection of a suitable ultrasonic-welding machine, but especially the constructive shape [...]
