Manufacturing Process
WIRES cable assembly overmolding utilizes a precision injection molding process to integrate a protective polymer layer. This WIRES manufacturing technique permanently encapsulates the cable and connector interface in a high-strength shell.
The process involves heating specialized pellets to a molten state within a high-pressure barrel. This material is injected into a custom WIRES mold containing the pre-assembled cable. As the material cools and hardens, it forms a seamless, ruggedized barrier that shields internal components from mechanical stress and environmental ingress.

Frequently Asked Questions
Customers choose WIRES not only for the value we deliver, but also for our responsive and detailed support. Here are some of the frequently asked questions we’ve compiled.
What is the difference between single-cavity and multi-cavity molds?
Single-cavity molds are designed to produce one part per molding cycle, making them more suitable for larger, more complex components that require higher dimensional precision and stable forming control.
Multi-cavity molds, by contrast, can produce multiple identical parts in a single cycle (typically 2–64+ cavities depending on tooling design). They are ideal for small-to-medium components with high order volumes, enabling higher production efficiency (up to several times output increase per cycle), shorter lead times, and lower per-unit manufacturing cost.
In industrial manufacturing and OEM production, selecting the appropriate mold type helps optimize cost efficiency, scalability, and delivery performance.
What is the minimum thickness for overmolding?
To improve production efficiency and bonding quality, the substrate and overmolded layer should maintain a uniform wall thickness. In most applications, a thickness range of 0.028 to 0.150 inches (0.711 to 3.81 mm) is recommended to ensure strong adhesion, stable molding performance, and reliable overmold durability.
What is the difference between insert molding and overmolding?
Insert molding involves placing a pre-formed component (often metal or rigid parts) into a mold, then injecting material around it to form a single integrated piece. It is commonly used for metal terminals, threaded inserts, and structural reinforcements.
Overmolding, by contrast, is a multi-step molding process where one material is molded over another (typically plastic over plastic or rubber over plastic) to create a layered structure within the same production cycle or sequential processes. This allows for improved grip, sealing, insulation, and aesthetics, but typically requires more complex tooling and higher mold costs.
In short:
- Insert molding: integrates pre-placed components (especially metal) into a single molded part
- Overmolding: bonds multiple material layers for enhanced functionality and performance
Does WIRES accept both large-volume and small-volume orders?
Yes, WIRES supports both small-batch and large-volume orders to meet different project needs. To date, we have delivered over 1,000,000+ cable assemblies across a wide range of industries, ensuring flexible production, consistent quality, and reliable delivery.
