A moulding method for making a small thin-walled metallic hose, including a mould piece 3, a pair of predetermined halves 43 and 44, and a punch for forging so as to process the small thin-walled metallic hose, characterized in that: place a metallic hose 1 in the pair of predetermined halves 43 and 44; to form a plastic bag depending on the shape and volume of hole 10 of hose 1; place the plastic bag to the hole 10 and inject liquid mercury to the plastic bag and seal the bag to form the changeable mould piece 3 in the hole 3; pressure the mould piece 3 of the hole 10 by punch 5, after the mould piece 3 being subjected to the stamping, the stamping force being transformed to the force of deformation to force the hose wall 11 to be the contour of the pair of predetermined halves 43 and 44.
