A manufacturing process where molten material (typically plastic) is injected into a custom mold cavity to produce high volumes of identical parts with tight tolerances.
Injection molding is a manufacturing process in which molten material — most commonly thermoplastic or thermosetting polymers — is injected under high pressure into a precision mold cavity. Once cooled, the material solidifies into the shape of the mold, producing identical parts at high speed.
Injection molding is ideal for high-volume production of plastic components with complex geometries and tight tolerances. While tooling costs are high upfront, the per-unit cost drops significantly at scale. It is one of the most commonly searched manufacturing capabilities on FindMyFactory, used across consumer products, automotive, medical devices, and electronics.
