There are three main stages in the injection moulding cycle. Reaction injection moulding rim is a method for rapid production of complex plastic parts. Reinforced reaction injection molding rrim in the rrim process two or more reactive resins are metered and impingement mixed under high pressure to form a thermosetting polymer injected into a mold and then cured. The injection pressure within the cavity is too low.
