He has personally overseen plant setups and production troubleshooting across India, and continues to operate Spectra Metal Shield as an active hard anodizing unit. He also supplies specialist anodizing chemicals — colouring salts, stabilizers, sealing salts, and etching finish chemicals — directly to Indian plants. When you engage Saravana Consultancy, you deal directly with him.

Typical greenfield anodizing plants take 8–14 months from site evaluation to first commercial run. Hard anodizing units add 1–2 months for chiller and bath cooling commissioning. Saravana Consultancy has commissioned 10+ plants on this timeline across India. ### What is the cost of setting up a hard anodizing plant? Hard anodizing plant capex ranges ₹2–6 crore for 50–200 m²/day capacity, depending on bath count, rectifier sizing, and chiller requirements. The dominant cost variables are current density target (typically 2.5–3.5 A/dm²) and required coating thickness (25–75 µm). ### Do you take on plant audits or only greenfield projects? Both. Production optimisation audits run 5–15 days on-site and produce a prioritised action plan. We have reduced rejection rates by 40–60% on multiple plant audits across India. ### Which standards do you follow for hard anodizing? MIL-A-8625 Type III for wear-resistant hard coats (25–75 µm), MIL-A-8625 Type II for sulphuric/decorative work (5–25 µm), and BS 3987 / AAMA 611 for structural architectural anodizing. ### Do you serve plants outside major Indian cities? Yes — we conduct site visits across India for greenfield projects and audits. Same-week availability for urgent troubleshooting issues; standard visits scheduled within 2–3 weeks.
