The Metallurgical Sequence
Material Formulation
Proprietary powder recipes blended and homogenized for each application — including the nationally patented soft-magnetic ABS gear ring formulation.
Compaction & In-Line Weight / Density Control
25 fully automated molding machines from 25T to 630T form green compacts with 100% in-line weight and density inspection.
High-Temperature Sintering
Controlled-atmosphere sintering furnaces drive solid-state diffusion into high-strength metallurgical bonds.
Precision Sizing & CNC Machining
Secondary coining dies and CNC finishing correct thermal variance to final gear-class tolerances.
Surface Treatment & Performance Testing
Surface hardening and rustproofing, then gear testing center, CMM, ABS signal simulation and salt-spray validation before dispatch.
