The present and future of ultrasonic welding technology











The requirements of components for the electronics industry have become increasingly complex and wide-ranging: Tightness, accurate dimensions, and the impeccable visual appearance of surfaces are typical quality criteria.

Ultrasonic welding allows for cost- effective production and ensures high degrees of production safety and reproducibility of the joining process.

Application groups

Sensors, switches

In all areas of automation, optical, inductive, and capacitive sensors are used for millions of applications. Ultrasonic welding fulfills the requirements for perfect surface finish, scratch-free display plates, tightness and reliable function of electronic components.


Highest quality and design requirements particularly apply for housings. These include strength and tightness, absolute dimensional accuracy, high-quality and scratch-free surface finish, as well as clear welds.

Electrical devices

In addition to housing and display components, it is possible to include electronic components by means of welding or staking. Ultrasonic welding technology allows direct feeding of energy into the joining zone. It’s only possible during the actual welding process and it ensures secure joints of carrier plates and housings. This method avoids putting sensitive electronic parts at risk.

Cable and quick disconnect systems

Male connectors and terminal strips are high-quality safety components and are used in electrical devices, in electronics, and in electrical installations. Strong and faultless connections of contacts ensure trouble-free fit and safe current flow. Bonding of contacts by means of ultrasonic technology is a method that allows for connection of different types of materials.
