What Sujan Industries does

Sujan Industries is a privately held Indian industrial manufacturer, established in 1978 and headquartered in Vasai (East), Thane, Maharashtra, operating as part of the Sujan Group conglomerate. The company designs, develops, and manufactures critical-application rubber products, rubber-to-metal bonded items, anti-vibration mounts, seals, gaskets, custom moulded rubber parts, and stainless/carbon/alloy steel castings (5 kg to 1,000 kg per piece; 3,600 MT annual capacity) using compression moulding, injection moulding, transfer moulding, extrusion, and foundry processes across two Vasai-area plants and a US warehouse in Wayne, Illinois.

Sujan serves six primary verticals: Railway (railcar components, side bearings, draft gear pads, ballast brooms for Indian Railways, US Class I rails, and African railroads), Aerospace (CEMILAC-approved K-seal for India LCA, O-rings, fire-retardant seals), Defence (NBC pads, grommets, anti-vibration products for vehicles and missiles), Automotive (engine mounts, brake diaphragms, NVH components for HCV, 4W passenger cars in ICE and EV, E-Bus, and E-Scooter), Power (O-rings, cylinder head gaskets, mounts for generators and engines), and Electrical (insulating sleeves, bushbar joint boots, dampers for switchgear and transformers). Certifications include ISO 9001:2015, IRCLASS, TUV NORD, CEMILAC, AAR-M901E, AAR M948, and API 6A, providing regulatory access into highly demanding end markets.

The company earns revenue primarily through direct B2B sales of industrial components (hardware sales) via enterprise field sales to Indian OEMs, government buyers, and overseas customers (DDP/FOB/Ex-works). A long-running joint venture with US-based Miner Enterprises (since 2004) supplies TecsPak elastomer side bearings and gives the company privileged US railroad distribution. In 2025, Sujan extended its product surface into AI- and IoT-driven Smart Wagon and Smart Coach platforms, pantograph condition monitoring, and AI-powered obstacle detection, in partnership with RailVision and Transmission Dynamics, with the aim of moving from pure component supply toward software-enabled rail services.
