Abstract A manifold, especially a supply or receiving tank in a heat exchanger, is provided as an extruded/drawn tube (2) with outwards, longitudinally running protrusion part (3). Fastening flanges (4) with a diameter larger than the width of the protrusion part are an integrated portion of the pro- trusion part. The manufacturing method comprises extrusion or drawing of the shaped tube (2) with protrusion part (3), per- forating of the protrusion part resulting in a plurality of apertures (32) which are transformed in one or more steps by cold deformation into fastening flanges (4) of desirable dia- meter, shape and length.
