Often our clients bring us projects that involve combining a variety of plastic and metal components. Traditionally, this was achieved through additional secondary services or more complex assemblies. But with the advent of insert molding and its counterpart, overmolding, it is now easier, faster, and cheaper to create complex finished projects.
What is Insert Molding?
Both insert molding and overmolding follow a similar process, and each has benefits, depending on the application.
How is Insert Molding Used?
Insert molding has practical uses in a wide variety of industries, from industrial and consumer to aerospace and medical. This process can be used to create:
- Electrical components
- And more
The insert molding process is similar to traditional injection molding: solid pellets of raw material are melted and extruded into a mold. The plastic is solidified, the press opens, and the molded parts are ejected. For insert molding, the insert is placed inside the mold – either by machine or by hand – before the material is injected into the mold. This allows the material to flow into undercut features in the insert, anchoring it more securely than if it were assembled to a previously molded component.
There are a variety of inserts that can molded into plastic components, including:
- Spring contacts
- Surface mount pads
- Threaded fasteners
