Precision CNC machined electric vehicle components for OEMs and EV startups worldwide. ISO 9001:2015 certified. CMM inspected. From prototypes to full-scale production.
✓ No minimum order ✓ Prototypes welcome ✓ NDA available

Electric vehicles demand tighter tolerances, lighter materials, and more complex geometries than almost any other manufacturing sector. A battery enclosure that seals imperfectly risks thermal runaway. A motor housing with a 0.05 mm bore error causes vibration that reduces drivetrain life. A thermal management plate with uneven channel depth compromises battery temperature control — and battery temperature is the single biggest determinant of EV range and pack longevity.
Robocon CNC has been manufacturing precision components for India's growing EV sector since the early production of Ola Electric, Ather Energy, and Tata EV platforms. We machine battery enclosures, motor housings, heat sinks, inverter housings, structural brackets, and high-voltage connector interfaces from aluminum, stainless steel, titanium, and engineering plastics — with CMM inspection on every critical dimension and full material traceability as standard.
From prototype to production, we scale with your programme — no minimum order on development parts, volume pricing from 25 pieces, and dedicated tooling for high-volume supply agreements.
Critical electric vehicle components manufactured to tight tolerances with full CMM inspection — supporting OEMs, Tier 1 suppliers, and EV startups globally.

Custom CNC machined battery pack housings with precision sealing interfaces, thermal pathways, and structural integrity. Lightweight aluminium 6061 and 7075 with Type III hard anodizing. Tight flatness tolerance on sealing faces — critical for IP67/IP68 pack ratings.

High-precision motor housings, gearbox interfaces, and drivetrain brackets machined to exacting bore tolerances — typically H6/h5 fits for bearing seats — to ensure efficient power delivery and minimise vibration.

Precision heat sinks, liquid cooling plates, and thermal interface components for EV power electronics and battery systems. Channel depth and width machined to ±0.05 mm for uniform coolant flow.

Enclosures and mounting interfaces for inverters, DC-DC converters, and motor controllers. EMI shielding slots machined to IPC tolerances, integrated cooling pathways, and precise connector cutouts.

Lightweight, high-strength brackets to integrate batteries, motors, and electronics into EV platforms. 5-axis machined weight-reduction pockets in aluminium 7075 — up to 40% weight saving versus solid billets.

Precision machined terminals, connector housings, and interface plates for 400V and 800V EV architectures. Exact alignment tolerances of ±0.01 mm on connector pin bores per IEC 60664.
±0.005 mm standard tolerance on safety-critical EV dimensions — bearing seats, sealing faces, connector bores. CMM verification on every critical feature.
Mazak Variaxis 5-axis simultaneous machining for complex EV geometries — cooling channel profiles, multi-face battery enclosures, compound-angle motor brackets in a single setup.
Deep experience machining thermal management components — cooling plates, heat sinks, and liquid channel manifolds with the channel depth accuracy that maximises heat transfer.
CMM inspection reports, material traceability certificates, FAI documentation, and PPAP Level 1–3 — everything EV OEMs need for supplier qualification.

We manufacture battery enclosures, motor and drivetrain housings, thermal management heat sinks and cooling plates, inverter and power electronics housings, structural and mounting brackets, and high-voltage connector interfaces for electric vehicles — for OEMs, Tier 1 suppliers, and EV startups.
Standard tolerance ±0.01 mm. For safety-critical EV features — bearing seats, sealing faces, connector pin bores — we achieve ±0.005 mm with CMM verification. Cooling channel depth typically held to ±0.05 mm.
Yes. We supply both — from single-piece prototype battery enclosures for early-stage EV startups to production runs of 5,000+ parts for established automotive OEMs. No minimum order on development parts. Volume pricing from 25 pieces. We have supplied Tier 1 suppliers in the Ola Electric and Ather Energy supply chains.
Aluminum 6061-T6 and 7075-T6 for battery enclosures, heat sinks, and structural brackets. 316L stainless for corrosion-resistant fluid fittings. Titanium Grade 5 for high-strength lightweight applications. Brass and copper for high-voltage connector interfaces. PEEK and Delrin for insulation fixtures.
