At Šumer d.o.o., insert moulding combines metal and plastic in a single step. A metal part is placed in the mould seat, and when the tool closes, plastic fills the cavity around the insert, creating one strong, integrated component. This process, also known as metal-plastic overmoulding, combines the structural strength of metal with the design flexibility of plastic.

Insert moulding is an effective alternative to assembly using force or adhesives. The bond is strong, precise and consistent across both small and large production batches. It is widely used in automotive, electronics and industrial applications where durability and tight tolerances are essential. Our processes are certified to ISO 9001 and IATF 16949.
