Abstract: Method for injection moulding one or more parts using an injection moulding machine and tool including at least one mould cavity, and a feed system comprising at least one gate and at least one runner that is located upstream of the at least one gate. The at least one runner includes at least one moveable wall and the method includes changing at least one cross-sectional dimension of the at least one runner by moving the at least one moveable wall in order achieve at least one of to vary a flow rate of material in the at least one runner, to apply a holding pressure to material in the at least one runner and consequently to the at least one mould cavity, or to compress residue in the at least one runner.

Abstract: Method for injection moulding one or more parts using an injection moulding machine and tool (12, 13) comprising at least one mould cavity (17), and a feed system comprising at least one gate (18) and at least one runner (19, 20, 21) that is located upstream of the at least one gate (18). The at least one runner (19, 20, 21) comprises a at least one moveable wall and the method comprises the step of changing at least one cross-sectional dimension (T, B, H, S or S+?S) of the at least one runner (19, 20, 21) by moving the at least one moveable wall in order achieve at least one of the following: a) to vary a flow rate of material in the at least one runner (19, 20, 21), b) to apply a holding pressure to material in the at least one runner (19, 20, 21) and consequently to the at least one mould cavity (17), c) to compress residue in the at least one runner (19, 20, 21).
