What Patronage does
Patronage Filtex India Pvt. Ltd. is a Kolhapur, India-based manufacturer of ceramic foam filters used for molten metal filtration in foundry and metallurgical applications. Founded in 2009 by Shakun Shah and Nikhil Shah, the company initially traded imported foundry materials before transitioning to domestic manufacturing in 2016 after developing proprietary Silicon Carbide ceramic foam filter technology, becoming the first Indian manufacturer of these filters under the Make in India initiative. Today the company produces three product lines under the FILTEX brand — FILTEX SIC (silicon carbide, 80–87% porosity, up to 1500°C operating temperature), FILTEX AL (alumina, 1100°C), and FILTEX ZR (zirconia, up to 1700°C) — along with refractory gating system shapes and, via its 2023 subsidiary Patronage Micro Minerals, premium silica sand.
The business operates as a capital-intensive B2B industrial manufacturer serving ferrous and non-ferrous foundries, steel casting facilities, and aluminum cast houses. Distribution is direct-sales-only with no intermediary channels: PAN India supply within India and direct exports to 7+ countries including Taiwan, USA, UK, Iran, UAE, Russia, Turkey, and Saudi Arabia. Pricing is quote-based with no publicly disclosed price list. Logo customers include Hindalco Industries, Electrosteel Castings, Alicon Cast Alloy, Precision Camshaft, Laxmi Pumps, Saudi Mechanical Industries, NAFFCO, and government/defense customer Vikram Sarabhai Space Centre — a reference list of 500+ cumulative clients. Marketing relies on corporate website content, LinkedIn, YouTube, downloadable catalogues, and trade show participation (IFEX 2020).
Production scaled from 1M filters/month in 2017 to 8M filters/month at a new 3-acre state-of-the-art facility launched in 2024, supported by 150 employees. The company is privately held, founder-owned, and bootstrapped with no external equity, debt, or institutional capital disclosed in the source material. The vertical integration into silica sand through Patronage Micro Minerals (2023, 8-acre plant) signals an intent to control key raw material inputs and diversify revenue beyond ceramic foam filters into adjacent industrial and construction supply markets.
