Thinking Overmolding? Here's Why It's a Good Decision
If you’re contemplating whether to choose overmolding for your next product or part but aren’t 100 percent sure, it never hurts to think and then rethink. But to remove any shadow of doubt, here’s why overmolding will only continue to grow in popularity - and why it’s a solid choice.
What is overmolding again?
Overmolding is a unique injection molding process that results in a seamless combination of multiple materials into a single part or product. It typically includes a rigid, plastic-base component that is overlain by a thin, pliable, rubber-like thermoplastic elastomer (TPE) exterior layer or other materials. Two types of overmolding techniques used to combine the TPE layer and plastic substrate are single-shot (insert molding) and two-shot (multiple-shot molding).
