"Leak test of battery housings", technical article in the yearbook 2022 Dichten. Kleben. Polymer. of ISGATEC
Since there is no standard for batteries today and efficient leak testing depends on many factors, there is also no standard for leak testing. However, if the central challenges are known, suitable testing strategies can be developed quickly.

Premium Remote Service
In the run-up to the commissioning of leak test panels and during the commissioning itself, there is now special support for machine builders: the Premium Remote Service. Experienced service engineers help to analyse leaky compressed air connections, seals and feeds that would prevent smooth commissioning of the leak tester. Support is provided via remote access - the components required for this are available from JW Froehlich. A fixed hourly quota is included.
read moreImmanuel-Kant-Gymnasium was founded 40 years ago and for the last 5 years has been involved in a training partnership with JW Froehlich GmbH.
The Immanuel-Kant-Gymnasium took this occasion to celebrate with a revamped school fair.
Alongside joint presentations by pupils and teachers, the numerous visitors were treated to a richly varied programme.
Within the course of the address for the 5-year anniversary of the educational partnership between JW Froehlich GmbH and the Immanuel-Kant-Gymnasium grammar school, we have awarded the JW Froehlich scholarship, for the third time already, to a high school graduate who achieved above-average grades in the area of natural sciences and who is now starting their technical studies in cooperation with JW Froehlich.
The JW Froehlich GmbH film team also followed the day with the camera. We have compiled the resultant video into a short film that provides a pleasant insight into the Immanuel-Kant-Gymnasium.
