Overmolding is a process where a
single part is created using two or more different materials in combination.
Advantages of Overmolding
Rubber-like TPEs/TPVs on the exterior of plastic parts can help the piece resist water or absorb sound. The TPE/TPV layer can also serve as electrical insulation.
Overmolding can help keep dust and water out of plastic components, making them last longer.
Overmolding can help add a second layer that can make grips more comfortable on any parts that people hold or grasp.
