Precision forging & EV driveline
What it is
Transmission and driveline components - gears, shafts, differentials, steering parts - are precision-forged and machined to tight tolerances. An EV replaces the multi-speed gearbox with a single-speed reducer, reducing part count but not eliminating driveline content
Forging capacity utilisation drives fixed-cost absorption
Impact on industries
- Precision forging capability is a genuine moat - tolerance, metallurgy and capacity cannot be replicated quickly, and qualification is platform-specific
- EV drivelines need far fewer gears than a multi-speed gearbox, so content per vehicle falls even where the supplier wins the platform
- China-plus-one sourcing has opened global driveline supply to Indian forgers, and export orders diversify away from domestic ICE exposure
- Forging is capital-heavy so utilisation dictates margin, and lagged steel pass-through swings reported margins independently of performance
