The invention provides a universal hydraulic press for injection-moulding where two separate clamping units, each with a respective mould, are arranged in parallel and are adapted to be brought into alternate engagement with each of two injection units in which a different moulding material may be housed. One of the moulding materials may be injected into one of the moulds following which indexing movement brings the other injection unit into register with that mould for injecting the second material onto the first.
