About Insert Parts

An insert part specifies the part body that represents an overmolded part insert.

Insert overmolding is a technique that includes an insert (typically made of metal), which is placed into the injection mold prior to molding, and melted plastic material is then injected into the mold to fill the cavity and mold around the inserted component. Insert molding can often result in stronger, more lightweight products since the insert helps add stability and strength without the need for multiple parts.

Inserts can include metal stampings, bushings, electromechanical parts, filtration materials, and other discrete parts. Materials are carefully chosen to bond together, using the heat from the injection of the plastic material to form that bond. This avoids the use of adhesives or assembly of the completed part. It can result in a robust multi-material part with a high quality finish.

Insert parts can be specified by picking the part body from the Specify Insert Parts list or by clicking directly on the Part body.
