Ultrasonic Welding

Ultrasonic welding uses ultrasonic vibration and external pressure to melt and join two thermoplastic resin workpieces.

An ultrasonic welding machine consists of an ultrasonic generator that creates high frequency AC to generates electrical energy, an oscillator that converts the electrical energy into mechanical vibration, a press unit that applies pressure and the horn that applies the vibration and pressure to the workpieces to be joined.

Ultrasonic welding is suitable for mass production due to its short welding time (around 1 second) and easy integration into automated processes. It also creates high quality welds without the use of adhesives or solvents.

This joining solution is used in many applications such as large containers for automobiles and home appliances as well as food and medical packages.
