<p>The invention refers to a method for injection moulding of product incorporating an upper part (11) and at least one connection integrated therewith, and where the mould chambers (16) of the upper part have flow paths of different length in different directions from a melt intake (15), whereby adjustable cores (19) in said mould chambers (16) are individually adjusted for giving different flow resistance in different parts of the mould chambers for the purpose of ascertaining that the melt will reach all parts of the moulding chamber of the upper part substantially at the same time, and also a tool for performing the method, which incorporates a combination of a fixed tool half (13), a movable tool half (14) incorporating mould pressure cores (19), which are arranged to be movable in a direction in towards a moulding chamber (16), which is in contact with a melt intake (15), moulding cavities (17) for connections provided in movable connections cores (30), which moulding cavities (17) are in contact with the moulding cavity (16) via restrictable openings/flow channels (18).</p> |
