Our History

Founded in 1969 and originally located in the heart of the Silicon Valley, Huntington Mechanical Labs began designing and manufacturing high and ultra-high vacuum components and systems for research laboratories. Driven by demand created by rapid growth in semiconductor and other industrial vacuum applications, Huntington quickly became a leading supplier of standard vacuum components while maintaining expert status in custom component fabrication.

Vision for the Future

Huntington’s ongoing commitment to innovation and improved design allows us to offer one of the industry’s largest selections of chambers, valves, motion devices and accessories. Huntington strives to deliver vacuum integrity and suitable life cycle expectancy in every product we make, and to consistently meet or exceed the highest industry standards.

The fabrication of vacuum chambers and related components is one of Huntington’s core competencies. Over the years we have produced ultra-high vacuum chambers, motion devices and basic system components of all sizes and shapes.  From simple to complex we have produced products for system manufacturers and scientists doing research in Surface Analysis, Plasma Etch, Lithography, Sputtering Applications and more. Huntington products can be found in the semiconductor manufacturing industry as well as R & D labs around the world, and even to the Moon and back!



Huntington still believes in the value of quality products. Like so many in the industry we utilize the latest in CAD/CAM design and CNC machines for repeatable and accurate volume parts and assemblies. However, where we take the most pride, is in our skilled craftsmen and dedicated technicians to provide the highest quality custom components to our customers. With ongoing improvements in processes and procedures, updated training of technicians to improve quality and flow, to an eye on the environment and the footprint we leave behind – We’re Huntington!


Innovative Design

Huntington’s expertise in the design and manufacture of dynamic products, as attested to by multiple foreign and domestic patents, is one our greatest strengths. Our vacuum valves, manipulators and motion feedthroughs offer unique benefits of higher torque, smaller footprint, greater load capabilities and extended cycle life. Constant improvement in design and materials is a hallmark of Huntington Mechanical Labs.
