Testing and processing machines

Testing and processing machines

We manufacture processing machines for the production of car batteries. The testing, measuring and checking of the functions are essential process steps in battery manufacture.

Testing and processing machines – concept examples

We supply our testing and processing machines to battery manufacturers across the globe. For each individual machine we tailor the design to the customer’s specifications and to the on-site processes.

Alignment machine for terminals and sets
Alignment machine for terminals and sets
Alignment machine for terminals and sets

The machine is used to align the sets and terminals of open battery casings, that is, batteries without caps. Four plants operated by a large battery manufacturer have already been fitted with this machine.

Testing of the weld quality

… in the downstream testing machine, after the anode and cathode plates have undergone the short circuit resistance test again, the internal welds are then inspected.

High voltage leak detection

The battery seal is tested using a high voltage of approximately 10 kV. Insufficient wall thicknesses or leaks will result in a rupture.

In order to be able to trace the individual battery casings, a data matrix code and a plain text code are engraved into the surface of the battery casing. A camera system then checks the legibility of the data matrix code and performs a validity check on the code that has been read.
