Abstract

Press for transfer moulding synthetic resins has two heated plate movable axially relative to each other, a piston for the injection of the resin, and a mould assembly with an opening for the passage of the piston, an injection chamber, a moulding chamber and a passage between these two chambers. The moulds are rapidly interchangeable and are not fixed on the press assembly.
