Insert molding is an injection molding process that works especially well for parts that have threaded holes. It can also help you create better wheels, pulleys, fan blades, and other similar parts. 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.
Overmolding lets you combine multiple materials into one part. One material, usually a thermoplastic elastomer (TPE/TPV), is molded onto a second material, which is often a rigid plastic. Think about your toothbrush handle where the single piece has both rigid and rubbery components. It’s a great way to make plastic parts perform and look better.
