All three processes combine materials in a single part, but they solve different problems. Here’s how to tell them apart — and which page to read next.
| Process | How it works | Typically used for | Learn more |
|---|---|---|---|
| Two-Shot Molding | Both shots run in one mold, in one cycle, on one machine. | High-volume parts that need two resins precisely registered to each other. | You're on this page |
| Overmolding | A finished substrate is loaded into a second mold and a soft layer is molded over it. | Lower-volume soft-touch parts, or substrates from an existing mold. | Over Molding → |
| Insert Molding | A pre-formed insert — usually metal — is placed in the mold and plastic is molded around it. | Parts needing embedded threads, contacts, or structural metal. | Insert Molding → |
