Manufacturing Process
Cable assembly overmolding is an injection molding process. It adds a protective layer of plastic or rubber to cables.
The process begins by heating and melting plastic or rubber pellets in a barrel. Under high pressure, the molten material is injected into a mold containing the cable assembly. Upon entering the mold, the material rapidly cools and hardens, forming a high-strength protective shell around the cable surface. This shell shields the cable from environmental damage.
Customization Services
We offer multiple customization options to meet your cable assembly requirements:
- Logo: If your project requires special markings for differentiation or identification, we can customize a unique logo tailored to your specifications.

What Our Customer Say
What is the difference between single-cavity molds and multi-cavity molds?
Single-cavity molds are more suitable for manufacturing larger-volume products.
Multi-cavity molds are better suited for smaller-volume products with higher order quantities. A single mold can produce multiple products simultaneously, enabling rapid production, enhancing production efficiency and delivery cycles, while reducing manufacturing costs.
What is the minimum thickness for overmolding?
To shorten production cycles, the wall thickness of the substrate and overmolded layer should be as uniform as possible. Wall thicknesses ranging from 0.028 to 0.150 inches (0.711 to 3.81 mm) ensure good adhesion in most overmolding applications.
What is the difference between insert molding and overmolding?
The difference between overmolding and insert molding lies in the fact that only overmolding enables the continuous production of two or more distinct parts (using the same mold, the same machine, and the same production cycle). Overmolding molds are more complex, resulting in higher costs. Only insert molding supports the use of metal components.
