Domin

What Domin does

Domin Limited is a UK-based hydraulic engineering company founded in 2012 and headquartered in Bristol, specializing in electrohydraulic and electrohydrostatic actuation systems for the aerospace and automotive sectors. The company designs and manufactures hydraulic components — notably servo valves, radial piston pumps, and electrohydrostatic actuators — that replace legacy centralized hydraulic architectures with decentralized, wheel-corner or point-of-use pressure generation. Its technology is enabled by in-house metal additive manufacturing (laser powder bed fusion using maraging steel on Renishaw RenAM 500Q systems), which allows organic internal fluid galleries and consolidated part geometries impossible with traditional subtractive methods. Domin claims a 50% weight reduction versus legacy systems, 9 kW average power reduction per aircraft, 2-millisecond actuation with 99.9% positional accuracy, and 5x higher operating pressure (150 bar vs. 15-30 bar).

Domin's commercial portfolio spans aerospace components (electrohydrostatic actuators and servo valves for aircraft manufacturers targeting net-zero by 2050) and automotive active suspension (an electrohydraulic by-wire suspension system currently at B-sample with a large German OEM and slated for 2028 hypercar launch). Project Activate, funded through the UK Government's £4 billion DRIVE35 programme, extends the company into full active-suspension subsystems for zero-emission vehicles, integrating advanced electronics, embedded software, additive-manufactured hardware, and optimized control strategies validated through digital twin and hardware-in-the-loop testing. Revenue is generated via direct OEM supply on project-based, negotiated contracts, with no disclosed list pricing. Reported growth is 75% year-on-year for five consecutive years, with headcount nearly doubling in the past 15-18 months to a current range of 51-100 employees. The company is privately held with no disclosed institutional ownership.

Direct peers

• Bosch Rexroth: Global leader in hydraulic components, pumps, valves, and motion control. Competes with Domin in decentralized hydraulic architectures and OEM supply, and is the dominant incumbent Domin is displacing in active suspension and aerospace hydraulics.
• Moog Inc. Established US supplier of high-performance servo valves, electrohydraulic actuators, and motion control systems for aerospace and defense. Directly comparable to Domin in product (servo valves, electrohydrostatic actuators) and end-customers (aerospace OEMs).
• Festo: German pneumatics and fluid power specialist with active R&D into digitalized fluid power and decentralized architectures. Domin has explicitly appeared alongside Festo in industry panels on fluid power digitalization, signalling direct category overlap.

Broad incumbents

• Continental: Tier-1 automotive supplier with active suspension, brake-by-wire, and chassis electronics portfolios. Directly competes with Domin for by-wire suspension SOP slots at European OEMs.
• ZF Friedrichshafen: Major chassis and driveline supplier (including ZF Active Suspension) competing for active and semi-active suspension business at premium and volume OEMs.
• KYB Corporation: Japanese hydraulic damper and suspension OEM with global automotive supply. Comparable as an established hydraulic suspension supplier that Domin must differentiate against on weight and power efficiency.
• Parker Hannifin: Diversified motion and control technologies giant with deep portfolios in hydraulic valves, pumps, and servo systems across aerospace and automotive. Comparable as an incumbent supplier Domin must win against in OEM design slots.
• Eaton: Power management major with significant hydraulics and vehicle businesses (Aeroquip, Char-Lynn). Comparable as a broad incumbent competing for aerospace hydraulic and chassis electrification programs.

Emerging players

• Conflux Technology: Australian metal additive manufacturing specialist focused on heat exchangers and fluid handling components. Closely comparable technology play using LPBF for high-performance fluid components, though more focused on thermal than actuation.
• BWI Group: Specialist in advanced suspension and chassis systems including MagneRide magnetorheological dampers. Comparable as a niche chassis technology supplier pushing into premium OEM suspension slots.
