Application groups


Engine compartment

Tightness, pressure and burst resistance, and unrestricted functionality: ultrasonic welding fulfills these requirements for vehicle components in the engine compartment. In filters, the filter material must be reliably embedded and the weld must be resistant to both heat and cold.

Welding of filter material and acoustic foams

Functional components

Complete functionality, without restriction, of integrated functional elements is ensured in ultrasonic welding of such components. What is more, 100% control and documentation of weld process parameters is guaranteed. Using ultrasonics it is also possible to simultaneously punch and weld membranes functioning as pressure balancing element (DAE).

Welding of functional components: tight and dimensionally accurate

Exterior / lights

Strength, tightness, and dimensional accuracy but also scratch- and mark-free appearance are typical requirements. Ultrasonic welding is a low-stress process for components and makes complex component geometries possible.

Welding sensitive surfaces


Ultrasonics is not only suitable for joining plastic materials with each other, but also for joining plastics and other materials, such as metal, or wood. Even chromium components are suitable for ultrasonic staking. By means of sonotrode grouping, it is also possible to realize particularly demanding joining tasks, such as welding of large instrument clusters. Brilliant surface finish and precise gap control is achieved.
