Injection molding is a broad term used to describe one of the most important processes in the manufacturing industry. It’s a process that requires a mold, typically made of metal with a cavity in the shape of the desired part. Molten plastic is injected into the mold and ejected. The process repeats to produce thousands of identical parts. It’s safe to assume that every large-volume plastic part on the market has come from an injection molding machine because the benefits of using injection molding for production are numerous. These benefits include low cost per part, short cycle times, extensive materials, and compatible, in-tolerance parts.
Various sub-processes add further capabilities to this already versatile technology. This article will specifically explore insert molding vs. overmolding and the advantages of each.
