Overmolded Cable Assemblies & Customization

Posted by Consolidated Electronic Team on July 17, 2020 11:48 am | Comments Off on Overmolded Cable Assemblies & Customization

Cable assemblies enclose vulnerable wiring in protective sheaths and incorporate a nearly unlimited variety of connectors based on the intended use. Overmolded cable assemblies go a step beyond a simple sheath by enclosing the cable or wire and connector with overmolded material.

Cable or wire assemblies are placed within a mold, which is then injected with a pressurized molten plastic. Once the material hardens, it turns into a protective layer that seals the junction between the wires/cable and connectors to reduce the risk of damage.

Why Customize?

Customizing your overmolded cable assemblies is the best option for ensuring your electronics are protected. They are ultimately more rugged and cost-effective because the assemblies are seamless and essentially turned into just one comprehensive piece. The overmolding process allows customization of the following:

• Overmold materials.

  Different materials imbue the assembly with different degrees of chemical or moisture resistance, heat resistance, and more. There are a variety of common plastics available for overmolding. Polyvinyl chloride (PVC) is an inexpensive general solution, but only offers minimal protection against strong acidic chemicals. Conversely, polyethylene (PE) and thermoplastic elastomer (TPE) can withstand strong acids. Polyurethane (PU) and thermoplastic polyurethane (TPU feature good resistance to weather, aging, and other harsh environmental conditions, making them ideal for outdoor applications. Material selection is based on degrees of protection desired and compatibility with wire insulation or jacket materials.

• Color.

  During custom projects, manufacturers can add distinct colors and resins to the molten plastic. These colors can be used to match a company’s branding, color code the assembly according to instructions or regulations, or make the equipment more aesthetically pleasing. Custom colors can improve safety and organization, as well as increase the marketability of a product.

• Environmental suitability.

  Overmolded assemblies can be built with unique features and molded layers to protect the wires against
