INJECTION MOLDING DEVICE WITH INTERMEDIATE STORAGE SPACE

摘要

An injection molding device includes a continuously operating extruder and a discontinuously operating injection unit receiving plastic material fr om the extruder, The extruder has an extruder barrel which includes a plasticizing zone and a discharge zone, whereby the discharge zone is configured to provide an intermediate storage space and has a cross sectional area which is greater than a cross sectional area of the plasticizing zone. In this way, the discharge zone provides a buffer volume which is filled during the injection process and th en emptied again.
