Insert molding is an integrated process in which thermoplastic injection encapsulates a part, often a metal stamping, to create a discrete component that combines structural elements and environmental protection with specific embedded interconnect functionality.
There are several applications that naturally benefit from insert molding. These include electronic modules, sensors and medical devices in which there is an internal electronic circuit or other part that has to interface with the outside world.
The key challenge is to make the packaging watertight and structurally robust to protect the internal circuitry from damage, while simultaneously providing electrically reliable connections to the outside circuitry.
