A new, low-force version of the HiQ Dialog series of ultrasonic welders from Herrmann Ultrasonics, Bartlett, Ill., allows users to achieve repeatable welds with low welding forces down to 5 N, compared with the previous minimum of 20 N. The Low-Force HiQ is said to be ideal for welding the smallest precision mechanical parts in microelectronics or medical technology.


According to the company, its success with this unit is based on refined control technology and the matching precision actuator. These make it possible to precisely control a welding process lasting only 1.2 sec. The company’s Soft-Touch technology  reportedly makes it possible to slow down the sonotrode just before it touches the part, creatint a soft and clean weld joint. As with other HiQ Dialog machines, documentation of each welding cycle is recorded, an essential factor for medical applications.
