Engineering CAPEX estimate (INR) for setting up an anodizing line in India. Adjust capacity, automation, and process type to see line-item costs for tanks, rectifier, ETP, and civil work. Calibrated against 10+ commissioned plants.
The model sizes each major equipment block from your throughput target, then applies India-market unit rates calibrated against 10+ plants commissioned by Saravana Consultancy between 2018 and 2025. All figures are in Indian rupees and exclude land, GST, and customs duty on any imported equipment.
| Component | Sizing driver | India rate (2026) |
|---|---|---|
| Anodizing tank | Length = part length + 0.5 m; volume from 0.6 m × 1.2 m cross-section | ₹ 65-95k per kL (PP) · ₹ 110-160k per kL (rubber-lined MS) |
| DC rectifier | 2.5 A/dm² × instantaneous loaded surface area | ₹ 800-1,200 per A (12-30 V) · ₹ 1,400-1,900 per A (60-100 V hard) |
| Chiller | 1.2 kW thermal per kA rectifier output (Type III only) | ₹ 60-80k per kW thermal |
| ETP | 1.5× rinse-water consumption per shift | ₹ 8-15 lakh base + ₹ 1.2 lakh per kL/day capacity |
| Civil / shed | 2.5× anodizing-line floor area | ₹ 1,800-2,800 per sq.ft (tier-2 industrial) |

Talk to BalasubramanianA small manual sulphuric anodizing plant (under 50 sq.m/day) typically costs 25-50 lakh INR. A semi-automatic medium plant (200 sq.m/day) costs 75 lakh to 1.5 crore. A fully automatic large line (500+ sq.m/day) costs 2-5 crore. Hard anodizing adds 20-30% due to chillers and higher-rated rectifiers. See our full anodizing plant cost guide for breakdowns by use case.
Anodizing plant CAPEX covers polypropylene or rubber-lined tanks, DC rectifier with cooling, hoists or transporters, jigs and titanium racks, ETP and demineralised water plant, exhaust scrubber, instrumentation and control panels, civil and shed work, and commissioning. Land cost is typically excluded from line CAPEX.
DC rectifier cost in India runs 800-1,200 INR per ampere for 12-30 V switch-mode units, 600-900 INR/A for thyristor-based units. A 5,000 A rectifier for a medium Type II plant costs 30-55 lakh INR. Hard anodizing requires a higher voltage rating (60-100 V) which adds another 25-40%.
Yes — every anodizing plant in India requires an effluent treatment plant under CPCB and state pollution control board norms. A basic neutralisation plus chemical-precipitation ETP for a medium anodizing line costs 15-30 lakh INR, plus another 5-8 lakh for a demineralised water plant feeding the rinses.
This calculator gives a ±20% engineering estimate suitable for early-stage feasibility, bank pitch decks, and partner discussions. Final CAPEX depends on alloy mix, batch size, jigging strategy, and local civil rates. For a bankable detailed project report (DPR), engage a consultant for site-specific design.
