Over-moulding is a process of injection moulding that encapsulates a connector or cable assembly with a thermoplastic material. This provides additional protection against harsh environments, such as extreme temperatures, moisture, and chemicals. Other benefits include;

- Improved protection
- Increased durability
- Waterproofing
- Enhanced performance
- Resistance to vibration
- Increased product life cycle
- Tamper-Proof components

- Reduced contamination risk

Whether you need custom over-moulded cables for marine, medical, defence or industrial applications, we have the experience and capability to fulfill your requirements.


Cable First's mould shop consists of a variety of different machines, that cover the whole spectrum of injection moulding. Injection moulding is a versatile process that can be used to produce a wide range of plastic parts, from small and intricate components to large and complex parts. The process involves melting plastic pellets and injecting them into a mold cavity under high pressure. The plastic then cools and solidifies in the mold, taking on the shape of the cavity.

At Cable First we have full in-house design capabilities, with skilled team of toolmakers and CAD designers at our disposal. Meaning our dedicated design team can work with your designers and discuss your design proposals, and then using 3D design software create your specific mould tool.
