摘要： 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.

摘要： A mixing head for multicomponent plastics, especially polyurethane, in whose mixing chamber (2) a hollow piston (7) can be moved to and fro to control the component streams. The hollow piston contains an expulsion piston (8), which is movable independently of the hollow piston, and which can be passed through an outlet tube (3) which adjoins the outlet orifice (4). The end face (12) of the hollow piston forms, together with the mixing chamber wall (11) nearest the sprue, a shearing gap in which the components are mixed. As a result of the design and arrangement of the pistons (7) and (8), good mixing is achievable even under critical conditions, and the mixing chamber is also easily cleaned.
