Abstract Surface Forming Technology（SFT）and its technical characteristics are introduced in this paper，based
on the practices of PM machine part development. SFT follows the general limits of press molding technology.
SFT is a kind of combined application with both geometric and nongeometric elements to define the surface and/or
define the tooling surface which formed PM machine part directly. The geometric elements include dot，line，
face，and so on. The nongeometric elements mean word，pattern，texture，roughness，etc. The purpose of the applications
above is to meet the requirements of the product structure and function design，process development and/
or process management. In this paper，a series of typical application examples are presented to demonstrate the application
scenarios and application techniques of SFT，and to provide guidelines for SFT applied in PM machine
part development.
