Injection Molding OvermoldingOverMolding or Insert molding is the process of injection molding molten plastic around any substrate or insert.

There are many substrates used in insert molding, but the most popular over molded material is rubber.

One of the  benefit of OverMolding is that part assemblies can be reduced by eliminating one of he parts.  Even though overmolding adds to the cycle time (typically 25 seconds per substrate) it is still much faster than the secondary operations of marrying two or more components at assembly.  Furthermore, by overmolding rubber on top of a plastic substrate allows for thinner wall sections, thus reducing overall part weight and bulkiness.

Did you know you can over mold metal into parts?  It is possible to mix Insert and OverMolding. The end result is a part with different grades of plastics and metals.

Furthermore, Xcentric Mold & Engineering is one of the few injection molding companies that offer overmolding and insert molding services.
