Silicone overmolding of electronic components. Type-C interface is the main interface type for charging and data transmission of more and more electronic devices. For high-protection electronic equipment, such as mobile phones, speakers, drones, earphones, etc. that need to meet IP68 and IP67 protection requirements. Type-C sealing requirements are one of the important key points. Using liquid silicone injection molding technology, a precise silicone sealing ring is overmolded at the Type-C interface, which can play a waterproof and dust-proof effect.
