Plastic injection molding embodies numerous subsets of versatile manufacturing processes. Two distinct methods of plastic fabrication include overmolding and insert molding, each offering its own advantages. Insert molding is the process of molding plastic over an entirely different material, and overmolding is a method that adds a layer of material over an existing part. Though, this is not where their differences end. Let’s take a more in-depth look at the difference between overmolding and insert molding.

While thermoplastics have revolutionized manufacturing, companies sometimes need to incorporate other materials into their product design. That’s where multi-material injection molding comes into play. This versatile solution helps injection molding manufacturers produce complex components and parts while incorporating metals or other non-plastics into the final product. It’s the perfect way to simplify assembly and enhance product performance, but it requires the expertise of an experienced manufacturer. Let’s review how to achieve success with multi-material plastic injection molding.

We’ve all seen single-piece mass-produced plastic injection molding parts – crudely made small toys come to mind. This also extends to individual simple parts, where tolerances are wider, and it’s a game of volume over quality. But some industries and some clients need something else – not only a different kind of injection molding but also quality over quantity. Today we’ll be looking at low-volume electronic parts, a field of injection molding that requires flexibility and quality control on behalf of the manufacturer.
