Abstract
Apparatus for manufacturing a composite structure of metal or other material and injection moulded synthetic plastics is disclosed. The apparatus comprises three components (12, 14, 16) which can be moved between an open position in which they are spaced apart and a closed position in which they are forced into contact. The centre component (14) has openings (30) in it and the outer component (16) has protrusions (36) which enter the openings (30) in the component (12) and punch a strip (40) which is between the two components. The punched out element is forced through the centre component (14) into a moulding cavity defined by the components (12, 14) and the front faces of the protrusions (36). A plastics material injection point (18) is provided in the component (12).
