The tooling profiles of the anvils focus the energy and ensure the best  seal quality during the sealing of film.

In interaction with the sonotrode, the anvil produces and shapes the joint and thus is one of the core components of the ultrasonic sealing process. Sealing of films requires focusing of the energy by means of the tooling profile, which is mostly mounted to the anvil. Highest rigidity and plane parallelism ensure best joint quality. Anvil profiles are essential for the quality of the weld result and are produced to customer requirements and adapted to respective applications.
