The DIA-type large-volume press falls into the category of large-volume presses. It relies on six sets of primary anvils to synchronously compress the secondary chamber, featuring uniform pressure transmission, high overall rigidity and excellent deformation resistance, making it suitable for working conditions with heavy loads and long-duration continuous operation. Its integrated control system is equipped with high-precision sensor modules to conduct real-time monitoring and closed-loop regulation of pressure and temperature, effectively mitigating experimental errors. Compared with conventional models, it boasts a compact structure and rapid pressurization response. Capable of performing routine static ultrahigh-temperature and high-pressure experiments as well as partial dynamic pressure tests, it primarily serves specialized research fields including high-pressure physics, ceramic material modification and geodynamics.
