Cable Overmolding

Cable overmolding is a manufacturing technique that merges cables and plastics together. This process involves putting a cable into a mold and subsequently injecting melted plastic into it. After the plastic cools and solidifies, the end product is released from the mold.


Cable overmolding is a unique method for producing high-quality cable components. This technique not only enhances the strength and durability of the cables, but also adds an extra layer of protection to ensure superior performance.

Notes When Designing the Cable Overmolding Mold

1

When designing the mold, consider designing a reasonable pre-pressure value that can seal without crushing the cable skin.

2

The mold must be designed with a reasonable cable positioning method to ensure that the cable is sealed and does not crush or shift during the injection process.

3

Based on the actual structural characteristics of the product, pre-inserted structural features must be designed to reduce the difficulty of direct injection.

4

Create appropriate tooling fixtures or automation to improve actual production efficiency and ensure production cycle stability.

How Does Cable Overmolding Work

1

To begin, customize the mold to accommodate the cable overmolding. The cable overmolding can be placed by hand or by an automated process.

2

Next, inject the melted plastic into the mold cavity.

3

After cooling and solidifying, the plastic is combined with the cables.

4

Open the mold and remove the part.

5

Separate the part from the sprue and post processing.

How Does Cable Overmolding Work?

Explain Advantages of
Cable Overmolding

  • The extra layer of insulation offers improved shielding for the cable, safeguarding it against wear and tear, as well as damage from impacts.

  • Overmolding fills the space around internal components of the cable, which prevents them from moving or shifting inside the cable. This makes the cable less vulnerable to tampering compared to regular cables.

  • The ability of overmolded cables to flex within a certain range without compromising their durability and functionality.

  • Using overmolding can remove the need for clamps or fixtures, making it possible to assemble cable quickly and safely.

  • Overmolding allows for the tidy organization and management of cables. The solid-colored housing of the cables aids in systematic cable management.

Attention for Cable OverMolding

1. Make sure the cable surface is clean prior to injection molding.

2. Under the premise of filling a product, combined with a scientific trial mold method, it is best to steer clear of excessive injection speed and pressure.

3. Ensure that the mold temperature and material temperature are set at appropriate levels to avoid any deformation of the cable.

4. After the molding process is complete, it is important to promptly transfer the finished products to prevent them from accumulating and tangling, which can make them difficult to separate.
