Electromobility is on the rise. E-cars run on electricity that can be produced from renewable energy sources and therefore reduce CO2 emissions – an important step towards climate protection.
The managers at the medium-sized company Hugo Benzing GmbH & Co. KG in Korntal-Münchingen quickly recognized this new trend towards sustainable electric vehicles.

Protection against battery overheating

The world's leading manufacturer of safety elements also realized its expertise to be useful for the construction of electric cars.
This is how the safety experts started developing bursting membranes and bursting disks for e-mobility.
The patented safety valves release pressure into the ambient air in the event of thermal overheating in the battery.
By preventing an increase in pressure in the battery, they ensure the safety of the electric car.

High safety requirements in the production process

High safety requirements and constant quality controls in the production process are necessary to manufacture this vent valve. The valve consists of three parts, which are assembled in an automated production cell at Benzing.
"We initially built the parts by hand," retrospects Managing Director Christian Benzing. But it soon turned out that the demand for these bleeder valves from the automotive industry would increase dramatically. "We therefore needed large quantities," says Benzing. The enormous growth in capacity could only be achieved through automation. In addition, the safety tests of the individual parts could now be standardized according to defined, programmed processes and with the help of modern technology. This is where the expert knowledge of the mechanical engineering and automation company, WAFIOS Tube Automation GmbH from Simonswald in the Black Forest, has come into play.
