Insert Molding

Pilot runs, low volume production, bridge tooling

Insert molding is a great way to combine metal and plastics into one single part. It allows plastic to bond to inserts that go inside a mold cavity, helping you to create better parts.

Advantages of Insert Molding

Durabilty

Metal inserts will guarantee the function of threads and mitigate wear and tear over the part’s life.

Part Production

Insert molding is great for creating prototypes and production parts.

Strength

Because it’s a “one-shot” process, insert molding can produce stronger parts than overmolding and other processes.

Overview: What is Insert Molding?

Benefits Of Insert Molding

Done correctly, insert molding can help:

  • Eliminate assembly: You can make parts all at once instead of having to do assembly after the fact.

  • Reduce costs: Insert molding costs more than standard injection molding, but the costs are usually offset by the fact that you no longer need to do post-assembly.

  • Lower the size and weight of the part: A plastic part with a metal insert is generally lighter than an all-metal part.

  • Improve reliability: Metal inserts will guarantee the function of threads and mitigate wear and tear over the part’s life.

  • Improve part strength: Because it’s a “one-shot” process, it can produce stronger parts than overmolding and other processes.

       Insert Molding works especially well for parts that have threaded holes. It can also help you create better              wheels, pulleys, fan blades, and other similar parts.

What Are The Differences Between Insert Molding And Overmolding?

Both of these processes involve putting two types of materials together to make a part. However overmolding requires two steps: one to create the substrate and one for the overmold that goes on top of it. Insert molding takes only one step, which makes for stronger parts and a more robust structure.
