What is overmolding?
Overmolding is the process of using a foam application to mold over a tube, pipe, or piece of metal. The process has the capability to change the aesthetics and performance of a piece of equipment. While its primary application is to provide a clean, textured finish to an application, overmolding can also be used to address heat and noise concerns that may come up. The versatility and range of applications make the overmolding process a vital part of the manufacturing process. Though it is a relatively common process (for example, you may see overmolding on the handles of a pair of pliers), overmolding has many applications that are more complex and demanding.
