Precision Silicone Overmolded Connector Sections for Waterproof Cable Assemblies

Custom Silicone Overmolded Connector Sections

SiliconePlus provides custom silicone overmolded connector sections for waterproof cable assemblies, medical device cables, electronic connectors, automotive sensors, and industrial equipment cables. This product focuses on the silicone overmolded connector section only, not the complete cable assembly.

Product Overview

Using advanced LSR injection molding and silicone overmolding technology, liquid silicone rubber is molded directly around plastic, metal, wire, or cable connector substrates. The overmolded silicone layer helps create a seamless sealing structure, improve bonding strength, reduce cable bending stress, and protect the connector interface from moisture, dust, vibration, and environmental ingress.

Key Features

1. Seamless Silicone Bonding
   The silicone layer is molded tightly around the connector section to create a strong and clean overmold-to-substrate interface. This helps reduce gaps, peeling, leakage risks, and long-term sealing failure.
2. Flexible Strain Relief Design
   The ribbed silicone strain relief structure helps reduce cable bending stress and improves flex life. It is suitable for frequently moved cable assemblies, medical equipment cables, industrial control cables, and outdoor electronic devices.
3. Waterproof Connector Sealing
   The overmolded sealing section helps protect the connector interface against moisture, dust, sweat, and environmental ingress. IP67 and IP68 waterproof design support can be provided according to the final product structure and testing requirements.
4. Custom LSR Injection Molding
   SiliconePlus supports customized hardness, color, shape, sealing thickness, rib structure, surface texture, and bonding area according to customer drawings, samples, or application requirements.
5. Multi-Substrate Overmolding Capability
   We support silicone overmolding with plastic, metal, wire, cable connector components, and other compatible substrates. This makes the process suitable for complex connector structures and integrated sealing designs.
