Insert Moulding in the UK

112 of 446 verified UK manufacturers on cmgraph's Injection Moulding — UK lens offer insert moulding 25% of the cohort.

Moulding polymer around a pre-placed insert — typically brass threads, terminals or stampings — so the metal is captured in the moulding itself. Distinct from post-mould insert fitting, where inserts are pressed or heat-staked into a finished part.

Also known as moulded-in inserts or metal insert moulding.
