What Is Overmolding And Why Is It Important?

Overmolding is done through a process of injection molding in which two or more different materials are used to combine wires and make them into a singular component. To better understanding overmolding, it’s important to have a thorough understanding of how it works.

 

1.      The cable assembly is placed inside a mold

2.      Molten plastic material is poured into the cavity of the mold

3.     Once cooled, the plastic material solidifies into the shape of the mold and covers the junction point between the wire and its connector

The Many Benefits Of Overmolded Cable

So, why do people go through the trouble of combining wires into single components? The biggest advantage of doing so is increasing the longevity and reliability of cables and their components.

·         Better Flexibility

With overmolding, the flexibility at the cable exit is strengthened. You might subject the cable to more pulling and strain near its connector, and with the help overmolding, there are fewer chances of it pulling at the actual wires.

·         Tamper Proof

The slightest bit of tampering with cables can leave your components in a mess, and it could take hours or days before someone takes notice. By sealing the components with resin, you create a more tamper-proof casing.

·         Qualified IP certification

If you would like your cables to be IP-67 or 68 compliant, then overmolding is a great way to add a water-tight seal to your cables and make them waterproof. The IP certification can be very beneficial for your work.

·         Appearance and Quality

Instead of dealing with messy quality, overmolding helps improve the overall look and feel of your cables. This means you won’t have to shell as much for expensive metal backshells and still reap the benefits of higher quality.

Common Applications

If you find yourself working in conditions requiring your cable assemblies to face harsh and unexpected weather, constant sanitation, extreme and frequent strain on the cables, or exposure to dust, overmolding can help significantly. You could also just opt for it because you need your cable assembly to look as organized as it feels. Whether it’s industrial or medical applications, overmolding is widely used.
