A universal injection molding system has plural pairs of mold inserts that are engageable for mold cavities mounted on mold bases, respectively, on the relatively movable top clamp plate and base support plate of an injection molding machine. Rails on those bases hold the mold inserts in place in paired alignment. With the plates and bases closed to bring together respective mold insert pairs, the mold inserts are securely clamped in relatively fixed positions on the plates and bases. A multiple stage ejecting/stripping apparatus also is provided to strip parts from mold cavities, and a technique is provided to eject the sprue before the parts. Methods of facilitating set-up of an injection molding system and of injection molding also are disclosed.
