ABSTRACT:
An apparatus comprising a housing with a guide bore in which an expulsion plunger can move to and fro, a portion of the guide bore constituting a mixing chamber which is bounded by the end face of the free end of the plunger and by two nozzle bodies which can be slidingly introduced into the guide bore. The plastics components flow, via inlet channels, through the nozzle bodies into the mixing chamber, the corresponding inlet orifices in the nozzle bodies being exposed during the stroke of these bodies. The end faces of the nozzle bodies constitute a restrictor in the form of an adjustable gap, which gap represents the outlet orifice of the mixing chamber and causes additional mixing of the plastics components. Using the apparatus, constant and good intensity of mixing is attainable, over the entire injection cycle, when processing two reactive plastics components.
