About us

Founded in 2019, TCT specializes in the research, development, and manufacturing of high-end vacuum valves for critical industries such as semiconductors, photovoltaics, display panels, and vacuum coating systems.

TCT is a wholly owned subsidiary of Ringtech Instruments, a company established in 1992 and renowned for its expertise in semiconductor-grade ultrasonic cleaning systems. Building on this legacy, TCT inherits a commitment to quality, innovation, and long-term partnerships.

With a core team of seasoned vacuum engineers and professionals with global market experience, TCT is dedicated to advancing the localization of vacuum valve technology and intellectual property—breaking through long-standing market monopolies held by foreign brands.
