Abstract
An injection-molding method for selectively manufacturing molded parts with and without a breakthrough is disclosed. A molded part with a breakthrough is manufactured by positioning a mold core in a mold cavity, whereas a molded part without breakthrough is manufactured by removing the mold core at least partly from the mold cavity. The mold cavity delimited by a nozzle-side mold platen and an ejector-side mold platen. The mold core is movable relative to at least one of the mold platens, in particularly the nozzle-side mold platen, in an advance direction, where the mold core is closer to the nozzle-side mold platen and an opposite withdrawal direction.
