ABSTRACT:
An injection molding device includes a continuously operating extruder and a discontinuously operating injection unit receiving plastic material from 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 then emptied again.
