■ Types of powder metallurgy manufacturing processes 

(1) 1P1S : mixing-molding (P)-sintering (S)-(post treatment)

★Typical Density 7.1Max.g/cc

(2) 2P1S : mixing-molding (P)-sintering (S)-calibration (P)-(post-processing)

★Typical Density 7.1Max.g/cc

(3) 2P2S: mixing-molding (P)-pre-sintering (S)-repressurization (P)-main sintering (S)-(post treatment)

★2P2S : Double Press Double Sintering

★Process for increasing density (7.3∼7.5 g/cc)

(4) Warm Compaction :

Mixed-Forming (Warm Compaction, P)-Sintering (S)-(Correction, P)-(Post-treatment) 

★Process for increasing density (7.2∼7.3 g/cc)
