Insert molding for production parts
Plastimold provides custom insert molding—placing metal or other component inserts into the mold so plastic encapsulates or locates them in one shot. We specialize in threaded bosses, bushings, pins, electrical contacts, and structural interfaces that must hold position and performance across production lots.
Advantages of Insertmolding
Insert molding process (molded-in inserts)
Insert molding places a prepared insert into the cavity (or onto a core/fixture), then injects plastic so the resin flows around the insert and locks it in place as the part cools. Success depends on insert location, support against resin pressure, gate strategy, and shrinkage so critical features stay on datum. Typical handoffs mirror Custom IM discipline: DFM → tooling for reliable insert loading → T1 → FAI → production with in-process checks.
Insert types & applications
Common insert types include threaded inserts and fasteners, bushings and sleeves, pins and shafts, electrical/connector elements, and stamped or machined metal components that need plastic encapsulation for insulation, cosmetics, or structural support. Component inserts beyond metal are discussed when the material and mold plan support them
Design, tooling & production consistency
DFM for insert molding focuses on how the insert is located, retained, and protected during fill—plus wall thickness, knit lines, sinks around the insert, draft, and shutoffs that keep flash off critical threads or mating faces. We review load method (manual vs automated where volumes justify it), nest design, and inspection of insert presence/orientation before the shot.
Insert molding vs overmolding
Both processes combine plastic with another component; they solve different design problems. Prefer insert molding (this page) for metal or component inserts molded into plastic (threads, bushings, structural interfaces). Prefer overmolding for soft/hard multi-material layers for grip, seal, isolation, or soft-touch. If you are deciding between the two—or need both in one assembly—send the part model, insert/substrate notes, and service conditions.

Resin families follow the Custom IM materials conversation. We match plastic to insert and end-use during DFM. Bring your resin preferences and product requirements with the print package and we will help make it happen.
Quality & CNC support
Quality is built through design review, insert and material traceability, first-article planning, dimensional checks, and clear acceptance criteria. Plastimold maintains AS9100, ISO 9001:2015, ISO 13485, ITAR registered, and CMMC Level 2 Compliant. When inserts, nests, or molds need precision machining, CNC machining supports molds, fixtures, and metal insert prep alongside molding.
