Abstract
A foaming agent charging and mixing device comprises at least one mixing device and one foaming agent metering device, wherein the foaming agent charging and mixing device may be arranged between an plasticating screw and a mold. In order to improve the foaming agent charging and mixing device in a manner that the mixing with foaming agent is facilitated and at the same time a risk of obstruction of the foaming agent metering device is avoided, the foaming agent metering device is alternately opened and closed through the mixing device during operation thereof for supplying foaming agent to the plastic melting.
