This subsequently plastic-moulded bushing fulfils an important function as an insert in a plastic hybrid part that is used specifically in the bursting membrane of a car battery. This highly specialised component plays a crucial role in the safety functionality of the car battery, as it helps to ensure the safe release of pressure in the event of overheating or overcharging. The precise overmoulding with plastic not only ensures an exact fit, but also optimal sealing and insulation to protect battery integrity and ensure the performance of the battery system.
