Mold concept for serial production taking into account the best injection point location and placing the parting lines correctly for best ventilation results

Best compromise between manufacturability and market competitiveness.

Batteries must be protected from the effects of hazardous sources (thermal runaway). High-voltage batteries consist of interlinked lithium cells, are available from 12V to > 800V and today have an energy density of over 200 Wh/kg. Pressure compensation and emergency degassing elements are required for optimal protection.

We call it the Berstring®. The innovative Berstring® safety valve combines all the features necessary for comprehensive protection. The functional principle has been tried and tested many times and can be adapted to individual conditions.
Berstring® safety valves are offered for battery housings of different sizes and can exchange more than 500 l/h of air at a differential pressure of 70 mbar. In case of thermal runaway our Berstrings® open with a short notice <50µs. The air volume and the bursting pressure are up to your request.
