The invention relates to a plasticizing and injection unit (1) of an injection moulding machine To inject especially smallest amounts of plastic melt in an injection moulding tool for injection moulding of small and smallest parts in a process optimized way the unit comprises a screw cylinder (2) in which a plasticizing screw is arranged rotatable and axially movable and an injection element (4) comprising a piston-cylinder system (5, 6), wherein a metered amount of plastic melt, which is deposited in a section (7) of a cylinder (6), is expelled via an injection nozzle (8) into an injection moulding tool by an axial movement of a piston (5) in the cylinder (6), wherein a flow path (9) is arranged between the end of the screw cylinder (2) and the section (7) of the cylinder (6) and wherein the flow path (9) is free from valve elements. Furthermore, the invention relates to a method for injection moulding of a part.
