Hubei RTKings Instrument Co., Ltd. (Brand: RTKins) is a leading domestic provider of integrated high-temperature and high-pressure (HTHP) solutions, as well as one of China’s pioneering enterprises that introduced extreme HTHP experimental equipment and achieved full domestic production localization.

Back in 2015, the company independently developed and delivered piston-cylinder apparatuses, breaking the long-standing monopoly of imported equipment and filling the domestic market gap in this field.

To date, RTKings has built a comprehensive product portfolio covering a full range of large-volume presses including piston-cylinder assemblies, Kawai-type, Walker-type, DIA-type, rapid-pressure-boost DIA-type and D-DIA-type models. Custom capsule-style HTHP equipment tailored for biochemistry applications has also been launched, catering to extreme experimental research across multiple disciplines such as geoscience, materials science and biochemistry.

The company operates an in-house dedicated high-pressure experimental hall fully equipped with its self-developed full-series instruments with complete operating conditions. Researchers from all sectors are warmly invited to conduct experiments, test equipment, or negotiate joint research and other collaborative projects.

All RTKings instruments are independently researched, developed and manufactured. The company supplies a complete lineup of matching consumables alongside customized application solutions, delivering one-stop service encompassing "equipment + consumables + technical support". A professional team of application engineers can independently carry out all types of HTHP experiments, while providing full-lifecycle services including standardized operation training, custom experimental scheme design and on-site technical support.

In terms of technological reserves, the company holds over 150 authorized patents, including core invention patents. It implements rigorous full-chain quality control spanning special pressure-resistant material selection, high-precision precision machining and self-developed professional industrial control software. Every effort is made to deliver user-friendly, stable instruments and lower operational barriers for researchers.

Leveraging proprietary core technologies, RTKings HTHP equipment delivers precise control over an extensive temperature and pressure range: pressure exceeding 20 GPa and temperature above 1600 °C, with outstanding control accuracy and performance comparable to world-leading international standards. Widely deployed in cutting-edge research fields including deep Earth science, high-pressure physics, advanced functional materials, aerospace engineering, superhard materials and diamond synthesis, our products are supplied in bulk to key universities and institutes under the Chinese Academy of Sciences nationwide.

The company vigorously advances industry-university-research collaborative innovation by establishing long-term technical cooperation platforms with numerous prestigious universities and research institutions. It has participated in more than ten national key scientific research projects, driving the comprehensive localization of extreme-condition scientific equipment through continuous independent innovation. Our HTHP products have been successfully deployed at Jilin University, China University of Geosciences (Wuhan), Beijing Center for High Pressure Science and Technology Advanced Research, and various CAS research divisions, earning widespread recognition for their practical performance. The company also supports the HTHP subproject of CHIEF (Centrifugal Hypergravity and Interdisciplinary Experimental Facility), a major national science and technology infrastructure at Zhejiang University, as well as the Deep Earth National Science and Technology Major Project launched in 2025.
