From molten metal to line-ready component
Foundries, machine shops, a metrology lab and engineering services — vertically integrated so quality is controlled at every step.
Among the largest shell-moulded ferrous casting foundries anywhere
Three dedicated shell-mould foundries (Plants P1, P2 and ISIS) produce critical automotive and hydraulic components with full machining and sub-assembly. We cast intricate thin-walled components — down to 3.5 mm walls — including water-cooled parts, and hydraulic components with thin, complex internal ports delivered with the highest degree of as-cast dimensional accuracy.
| Material | Typical applications |
|---|---|
| Grey iron (cast iron) | Cylinder blocks, housings, brake components |
| Ductile iron (SG / nodular) | Safety-critical automotive & hydraulic parts |
| Malleable iron | Camshafts, brackets |
| Compacted graphite iron | High-strength, thermally loaded parts |
| Austempered ductile iron | Wheel hubs, high-wear components |
Steel & stainless steel foundry
Our newest foundry manufactures precision steel and stainless steel components, extending the Indo Shell materials portfolio to corrosion-resistant and high-strength applications.
PLACEHOLDER: Add steel foundry specifics — casting process (investment / shell / sand), alloys poured, weight range, monthly capacity, and 2–3 example components with photos.
Aluminium & copper alloy castings
A dedicated non-ferrous foundry manufactures custom aluminium castings and copper alloys accurately to national and international specifications — including gravity die casting for automotive and appliance applications.
PLACEHOLDER: Confirm current non-ferrous processes (gravity die / low-pressure / high-pressure die casting) and add capacity figures — the 2016 site's die casting pages contained duplicated filler text, so this section needs authoritative detail.
Precision machining & assembly
Three machining facilities — P3, P4 and Indo Shell Precision — take castings to finished, fully assembled components.
Turning
Multi-axis CNC turning units and CNC Swiss turning centres for high-volume precision parts.
Milling
Multi-axis CNC HMC and VMC machining centres with pallet changers for complex prismatic components.
Finishing
Honing, lapping and grinding units achieving exact final dimensions and surface finish.
Cellular manufacturing layouts designed for efficient, safe, high-volume production. [PLACEHOLDER: confirm current daily/monthly machining capacity]
Hub motors for electric two-wheelers
Indo Shell's five decades of casting and precision machining expertise now power the EV transition: we manufacture hub motors for electric two-wheelers, combining cast components, precision machining and assembly in-house.
PLACEHOLDER: Add hub motor specifications — power ratings (kW), motor type, monthly volumes, and whether design is in-house or built-to-print. A photo of the motor line will make this section a highlight.
Metrology & engineering services
NABL-accredited metrology lab
Advanced metrology laboratory of international standards, NABL-accredited to ISO/IEC 17025 since 2008 — providing calibration and dimensional assurance for every plant.
Engineering services unit
Computerised engineering services automate operations, monitor each process and strengthen process communication. Product development follows APQP/PPAP methodologies with full documentation, and our R&D team delivers VA/VE solutions that keep customers cost-competitive.
