Unimech signs deal to acquire Hobel Bellows for Rs 450 crore

Mumbai: Unimech Aerospace and Manufacturing Limited has signed a definitive agreement to acquire Hobel Bellows for Rs 450 crore.

Hobel Bellows is a specialised Indian manufacturer of metallic bellows and precision-engineered assemblies. The move will strengthen Unimech's manufacturing capabilities and expand its presence across high-value industrial sectors, it said.

The proposed acquisition, subject to customary closing conditions, is part of Unimech’s strategy to evolve into a globally competitive, capability-led precision engineering platform. The company said the deal would help it move beyond precision components into higher-value engineered assemblies and sub-systems.


Hobel Bellows operates a 180,000 sq. ft. manufacturing facility in Duvvada SEZ, Visakhapatnam, and caters to industries such as automotive, locomotive, power transmission, and water and gas. The company has a strong export-oriented business, with nearly 90% of its revenue derived from overseas markets including the UK, US, Singapore and China.

For the financial year ended March 31, 2026, Hobel Bellows reported provisional revenues of around ₹130 crore, supported by strong profitability and cash generation. Its client base includes global original equipment manufacturers (OEMs) such as Cummins and Wabtec.

Chairman and Managing Director Anil Puthan said the acquisition represents a “significant milestone” in the company’s growth journey, adding that it strengthens technological depth, manufacturing breadth, and customer relevance.

Unimech said the acquisition is expected to bring complementary capabilities to it, including advanced metal forming technologies, precision pipe bending, robotic welding, and high-end testing and validation systems. These capabilities are likely to enhance Unimech’s ability to deliver integrated manufacturing solutions.

Unimech said the deal would also create synergies through cross-selling opportunities, improved capacity utilisation, and expanded sector presence, particularly in locomotive and industrial applications. It is also expected to accelerate time-to-market by providing immediate access to established customer relationships and manufacturing expertise.

Singhi Advisors acted as the exclusive advisor on the transaction.

With this acquisition, Unimech will deepen its engagement with global OEMs and strengthen its position as a trusted partner for complex engineering solutions across aerospace, defence, energy, and semiconductors.
