Injection Molding Insert Molding

About Insert Molding

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 is brass threaded inserts and bushing.  In addition, many companies make custom inserts that can be insert molded.  It is really left up to the imagination when deciding what type of inserts can be over molded.

The benefit to insert molding is that parts can be mass produced faster than machining whole parts out of metal.  Even though insert molding adds to the cycle time (typically 15 seconds per insert) it is still much faster than cnc machining a part from a solid block.  Furthermore, by insert molding metals where necessary and replacing the rest of the part with plastic will in turn reduce the overall weight of the part.

Did you know you can insert mold plastic parts?  This process is called over molding and it lends itself when you need two or more different materials in the same part.

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