Understanding Silicone Overmolding with Metal Inserts
Silicone overmolding with metal inserts involves embedding metal components within a silicone rubber matrix during the molding process. This integration offers superior mechanical strength, electrical conductivity, thermal management, and enhanced environmental resistance. It is especially beneficial for applications requiring sealing, vibration damping, electrical insulation, and structural reinforcement.
This process typically involves two primary steps:
Placement of metal inserts into the mold.
Injection of liquid silicone around the inserts, which cures to form a strong, permanent bond.
