Domin’s European production base is capable of producing high quality components and systems, aided by in-house tool and gauge manufacturing. With over 4000 square metres of manufacturing space, we house more than 30 CNC machine tools, the majority of which are equipped with 5 axes.
Our state-of-the-art highly efficient machinery, running at low-volume or large scale, is able to repeatably produce demanding features maintaining tight tolerances throughout.
Our capabilities range from components measuring 2 mm in diameter right up to 1 m in length, from peek and aluminium to titanium, from ground spools & pistons to complex manifolds with thousands of different features. We can design and manufacture just about any hydraulics valve or system.
Complex prismatic components are machined on dedicated high-end 5 axis machine tools, many of which robot-fed for 24/7 lights-out-manufacturing.
Capabilities include machining hard metals, such as titanium and stainless steel, as well as aluminum and exotic materials. Aided by large backup cutting tool racks, several thousands of features are typically implemented on a given complex hydraulic manifold, as used for porting the fluid in an aircraft’s aileron flight controls.
Rotational components are produced on our CNC lathes, ranging from diameters of 550mm (vertical turning), down to 3mm on our swiss-type lathes.
All machine tools are equipped with live tooling, reducing setups and increasing overall manufacturing efficiency & quality.
Our range of grinding equipment – be it CNC (inside/outside diameter), as well as flat, eccentric, centreless and bore grinding – is essential in achieving tight tolerances required for functioning of hydraulic systems.
In-process measurement allows for diametric matching of spools & sleeves with all equipment housed in fully air-conditioned surroundings.
Domin makes use of the latest wire and sinker EDM technology, pioneering hydraulic matching techniques such as wire-EDM-turning.
Due to its high precision, lack of tooling requirement and non-invasive nature, this technology sees applications in both rapid prototyping and serial production environments.
Long aspect, tight and blind bores with numerous cross-holes requiring single micron finishes – Domin masters such challenging features by designing, implementing and controlling the entire manufacturing process in-house.
The latest vertical CNC honing technology is used to guarantee highly repeatable output at minimal cost.
Cylindrical and dimensional tolerances down to 0.002mm are achievable reliably — as are surface finishes of 0.01 Ra.
Domin’s honing machinery is capable of running fully automated, producing 5-digit quantities of precise bores per year.
Domin’s non-destructive testing capabilities encompass both magnetic and fluorescent inspection techniques, both NADCAP approved to international aerospace standards.
Innovative, high-frequency fatigue tests are used to safeguard the integrity of additively manufactured metal components.
Being a design leader in additively manufactured high value systems, Domin has long believed in the importance of understanding and mastering this technology in-house.
Our machines laser-melt metal components with industry-leading fatigue strength, a quality essential to the success of our products, which Domin has taken years to perfect.
A dedicated tool design & production department is essential in a quick turn-around of Domin’s designs & systems. Complex multi-step port reamers are conceptualized, ground and put to use within days; tailored end mills for hard metal roughing beat competitors’ catalogue products by a factor of 3-5.
All tools are re-sharpened internally after use, additionally lowering serial production costs.
Zeiss Prismo Navigator coordinate metrology equipment with integrated turntables, CMM shape testers, instantaneous optical laser inspection – all aspects of Domin’s products are verified and monitored using equipment which is capable of measuring tolerances an order of magnitude more accurate than required.

“The Domin S6 Pro is a high-performance valve that competes very well with the other major manufacturers in terms of motion control performance, particularly with position and force control.
The linear response of control output to flow of the valve allows it to be tuned easily and the response time and bandwidth are very good. The valve exhibits excellent force control and is very stable during motion.
In the testing we performed, we were not able to get the valve to misbehave or go unstable, which means the valve can handle very difficult control situations.”
"We have now fully transitioned from the Woodward HRT 15 gpm servo valve to the Domin S6 Pro servo valve for piloting the Olmsted 32mm, 40mm, 50mm, and 63mm high performance cartridge valves.
The Domin valves have proven to be very rugged and reliable with outstanding performance."
"The valve was within specs (in terms of pressure drop and response time) and was much better than the Moog D633.
This is very good news for the future tests we will be performing."
“The Domin S6 Pro performs exactly as you advertised, extremely responsive, small in size, and looks great!”
"The valve is well made, solid, looks great and has a nice finish. It has great hysteresis and good repeatability. We tested it thoroughly and were unable to find any faults."
“Domin is an outstanding organization to work with and the advancements they’re making with once “traditional” hydraulic servo products is a game-changer for the industry.
The Domin valves are highly responsive, true to spec, easily tuned, repeatable, reliable and extremely robust.”
"The Domin S6 Pro servo valve is the best servo valve we have ever seen. It has an incredible response time and is unbelievably tiny."
“Domin’s customer service is the only thing that outshines the performance of the valves. The valves performance, configurability & durability is simply unmatched.
We’ve been able to replace several OEMS valves with a single Domin valve. We’ve put the Domin into our harshest applications & it performed flawlessly.”
"The customer and myself are very impressed with the performance of the valve in such a small package."
