Overmold Cable


Overmold Cable is a hermetic cable material that is processed using an insert/injection molding process. That is, the cable assembly and molten material are injected into a mold and allowed to cool, forming the cable into a sealed assembly. Overmolded cables are well suited for a number of low cost and high reliability cable solutions. It can handle humid environments as well as extreme environments where tight sealing is required. Provides good mechanical strength and design flexibility. Especially in the medical industry, there is also a built-in strain relief feature.

Why choose overmolded cables?

With the current industrial development, overmolding is gaining more and more popularity due to its good appearance and functionality. The reasons for this are:

Overmolding materials

The common overmolding materials are PVC and TPU, but in order to cope with different environments, we also need to choose the right material according to customer needs and specific application environment. Generally speaking, PVC is the most cost effective material available:

  • PVC (polyvinyl chloride) is a common type of material that has good durability and moisture resistance. It can withstand good tension and has a wide range of uses.
  • Thermoplastic polyurethane (TPU) is good because it resists fracture and is highly elastic. TPU is especially suitable for cold areas.

Overmolding specific process

In the overmolded cable manufacturing process, the mold resin enters the molding machine from the hopper and is mixed with different additives in the molding machine depending on the application requirements. It is injected into the mold cavity by the injection screw. And the mold itself can be customized with LOGO or part number. In order to increase the production efficiency, we will use water cooling or oil cooling to increase the overmolding rate. When completely cooled, the overmolded cable assembly is produced. To check the compliance of the cable assembly production, we also perform a series of tests. This ensures that the quality is up to standard.
