Unimech Aerospace Approves ₹450 Crore Investment to Acquire Hobel Bellows Stakes
Unimech Aerospace and Manufacturing Limited has greenlit an investment of up to ₹450 crore to buy controlling stakes in Hobel Bellows Private Limited. The parent company will take a 24% stake, while its wholly-owned subsidiary, Innomech Aerospace Toolings Private Limited, secures the remaining 76%. This move positions Unimech to deepen its footprint in precision aerospace components amid rising demand for advanced manufacturing.
Transaction Details and Structure
The deal involves issuing equity shares, loans, and compulsorily convertible debentures, with payments made in cash across one or more tranches. Following the stake acquisition, Hobel Bellows Private Limited will purchase a 99.99% partnership interest in Hobel Bellows Co., the operating entity established in 2007. That firm posted a turnover of ₹123.74 crore as of March 31, 2026, reflecting steady growth in a niche market. The transaction avoids related-party conflicts, as no promoters or group entities hold interests in the targets.
Strategic Fit in Precision Manufacturing
Hobel Bellows Co. specializes in metallic bellows and flexible tubing assemblies critical for aerospace engines, turbomachinery, defence platforms, automotive engines, and industrial exhaust systems. These components absorb vibrations, thermal expansion, and pressure fluctuations in high-stress environments. Unimech views this as a logical extension of its precision-machined parts for aerospace and energy sectors. The acquisition grants access to specialized processes like hydroforming, thin-wall metal forming, high-temperature alloy processing, and precision welding—techniques that demand exact tolerances.
Climbing the Value Chain and Market Signals
Unimech aims to advance from standalone components to integrated engineered assemblies, a shift that boosts margins and customer stickiness in competitive supply chains. Aerospace manufacturers increasingly seek consolidated suppliers to streamline production and reduce risks. Shares of Unimech closed at ₹998.30 on the NSE, rising 5.28%, signaling investor approval for this expansion. As India's defence and space sectors grow, such deals underscore the push toward self-reliance in high-tech manufacturing.
