This overmoulded bushing fulfils an important function as an insert in a plastic hybrid component used in a vehicle battery bursting membrane. This highly specialised component plays a critical 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 plastic overmoulding ensures both an exact fit and also optimal sealing and insulation to protect battery integrity and to safeguard the performance of the battery system.
