Manufacture method of powder metallurgy support

The invention relates to a manufacture method of a powder metallurgy support, which is characterized by sequentially comprising the following steps of: firstly, pressing a support basal body (1), i.e. pressing metal powder into the support basal body with the density of 6.0-7.3g/cm , forming a structure on which a transition block (2) is placed on the support basal body, and sintering the support basal body (1) for 4-6 minutes in a sintering furnace at the temperature of 105-1300 DEG C in vacuum or in a sintering atmosphere filled with soldering aid; secondly, pressing the transition block; thirdly, placing the transition block (2) on a position of the support basal body (1), wherein the position is used for placing the transition block for welding connection; fourthly, measuring the size and precision after welding; and fifthly, processing the support basal body (1) on which the transition block is welded with vapour, thereby the manufacture process of the powder metallurgy support is finished.
