Process Outsert moulding
Similar to insert moulding. Here though, a larger metal part surrounds one or more plastic elements like distance pins, flexible snap-locks, turnable buttons etc.

A prepared sheet of metal with holes and gripping areas is placed in a mould. Then plastic is injected as in conventional injection moulding.

Tools investments are slightly higher than for injection moulding.
