There are companies that make headlines, and then there are companies that make history — quietly, steadily, for more than a century. Walchandnagar Industries Limited belongs firmly in the second group. Founded in 1908, this Pune-headquartered engineering house has spent 117 years building the machines, plants and precision components behind some of India’s proudest achievements: its nuclear power stations, its space missions, its naval frigates and its missile programmes.
Walchandnagar Industries — WIL to those who know it — is an ISO 9001:2015 certified company listed on the BSE and NSE, with a diversified portfolio spanning projects, products and high-technology manufacturing. The company says its legacy is one of pioneering achievements in Indian engineering and a deep contribution to nation building. Few companies anywhere in the world can match the breadth of that record.
Firsts that shaped a nation
WIL was the first to manufacture critical components for a nuclear reactor in India, the company says — and it went on to supply critical components for 235 MW and 500 MW nuclear power projects. It built the main propulsion gearboxes for Indian-built Navy frigates, and components for satellite launch vehicles for ISRO. Its name is woven into India’s space story: the company says it supplied critical components for India’s first Moon mission, Chandrayaan-I, and for its first Mars mission, Mangalyaan.
The list goes on. WIL supplied major critical components for Agni V, India’s intercontinental ballistic missile programme, and contributed to one of the largest optical telescopes in Asia. It was also the first company to build an indigenous sugar project entirely on its own strength — a milestone that set the template for an entire industry.
Plants that power everyday India
Beyond the headline missions, WIL’s engineering runs through the everyday economy. The company designs, engineers, manufactures and erects complete plants and machinery for the sugar, cement, boiler and mining industries, alongside heavy-duty gearboxes, castings and precision instruments. Its reference list, the company says, runs to more than 600 EPC, semi-turnkey and turnkey projects executed across three continents and over 20 countries.
The numbers tell a story of extraordinary scale: more than 100 cement plants commissioned in India and abroad, more than 80 greenfield sugar projects, over 540 boiler installations worldwide, more than 6,500 gearboxes supplied globally and over 3,400 centrifugal machines delivered internationally. Behind those figures stand WIL’s own manufacturing bases — the heavy engineering works at Walchandnagar, a foundry at Satara, an instrumentation plant at Dharwad, and a shore-based facility at Dahej — with its corporate and marketing office in Pune.

A trusted partner of India’s finest institutions
What sets WIL apart is the trust it has earned over decades. The company says it has worked alongside India’s Department of Atomic Energy, NPCIL, BARC, ISRO and the Indian defence establishment for more than 40 years — relationships built on precision, reliability and delivery on projects where failure is simply not an option. That same engineering discipline serves its customers in nuclear power, aerospace, missiles, defence, oil and gas, steam generation and independent power projects.
The scale of the business today reflects that standing: the company reported revenue from operations of ₹259 crore in FY25, and it continues to serve a large, proven list of satisfied customers across the world. From its Walchandnagar works to its Pune headquarters, WIL remains what it has always been — an Indian engineering house of rare depth, building the heavy, precise and critical things that let the rest of India rise.
For a company that began in 1908 and still shapes India’s most ambitious programmes today, Walchandnagar Industries is a shining example of Indian manufacturing at its finest — experienced, trusted and built to last.
