This paper presents the chosen results of ball pins hollow forgings forming by means of rotary compression. Theoretical research was based on numerical simulations, conducted using finite element method. The software Simufact was applied for calculations needs. During simulations, kinematics of material flow, strain intensity distribution, damage criterion according to Cockroft-Latham and temperature distributions were determined. Force parameters in the process were also determined and limiting phenomena were identified. Results from FEM modeling were verified in laboratory conditions. Ball pins hollow forgings forming tests were performed in a special forge aggregate. The obtained results fully confirmed the possibility of ball pins hollow forgings manufacturing by means of rotary compression.
