Advantages of Servo Driven Ultrasonic Welder

Ultrasonic welding is one of the most widely used processes for bonding polymers, valued for its speed, flexibility, and low cost. Recently, there has been a call for more controlled and consistent ultrasonic welding processes, as part designs become more complex and requirements more stringent.  There is also a need for strong, dimensionally consistent parts… Continue Reading Advantages of Servo Driven Ultrasonic Welder

Understanding Ultrasonic Stack

It is essential that the mating faces between an ultrasonic transducer/booster and a booster/horn be flat and parallel. If any air gaps remain, there will be a resultant loss in power output and efficiency. Coupling may be so poor that it might prevent the starting of an ultrasonic stack. The condition of excessive crowning, or… Continue Reading Understanding Ultrasonic Stack

Ultrasonic Welding Effects on Hearing

In air, sound is usually described as variations of pressure above and below atmospheric pressure. These fluctuations, commonly called sound pressure, develop when a vibrating surface forms areas of high and low pressure, which transmit from the source as sound. Although noise-induced hearing loss is one of the most common occupational illnesses, it is often… Continue Reading Ultrasonic Welding Effects on Hearing
