Abstract

The invention relates to an injection moulding apparatus (1) comprising at least a first mould plate, the first mould plate comprising a first injection inlet (3) arranged in fluid connection with a first gate (4) leading into a mould cavity (2) and a second injection inlet (5) arranged in fluid connection with a second gate (6) leading into the mould cavity (2). The first and second injection inlets (3, 5) are arranged to open in sequence. The second gate (6) comprises a first gate volume (11) leading into the mould cavity (2). The second gate (6) is further provided with a second gate volume (12) allowing injection material to flow into the second gate volume (12) at the same time as into the first gate volume (11) and thereafter into the mould cavity (2). The invention also relates to a method for reducing a velocity increase of a flow front (10) during injection moulding.
