摘要

The device (1) is for filtration and mixture of plastic (2) in connection with injection moulding, using an injection mouthpiece (3) and including an insert (4) and an enclosing casing (5) with channels (6,7) in it for through conduction and feed of plastic in liquid form to the mouthpiece front injection part (8). Between the insert and the enclosing casing are several axially extending inlet channels for plastic. From these channels extends a gap (10) acting as filter for the plastic to an axially extending track (11), from which holes (12) lead to a common axially extending mixing and outflow space (13) in the insert.
