Method and component of a hot-injection apparatus

Component, of an injection molding apparatus, configured to be mounted within a manifold for molten material as a junction between

• a supply channel, which has a first axis, and
• an injection channel, which has a second axis and leads to an injection nozzle for injection towards a mold cavity,
• wherein
• a nozzle shutter crosses the feed channel and the component along the second axis,
• the supply channel and the injection channel are made inside the manifold of the apparatus,
• the first axis and the second axis are substantially incident and form a direction change angle for the molten material,
• the component comprising:
• an outer surface comprising inlets adapted to receive the molten material arriving from the supply channel,
• a central cavity which is in fluid communication with the injection channel to send the molten material there,
• internal channels which cross the thickness of the component and are adapted to put said inlets in communication with P outlets in the central cavity through P terminal channel sections, P>=3,
• wherein the terminal section of each internal channel in proximity of the respective outlet develops so as to introduce the molten material into the central cavity according to an introduction direction directed towards the injection channel,
• wherein the introduction directions of the P terminal sections:
• are contained in a reference plane passing through a third axis parallel to the second axis,
• are arranged circularly around the third axis, and
• form an introduction angle 0<α<90° with respect to a plane orthogonal to the third axis.
