High temperature and high pressure equipment full solution provider

China's leading high temperature and high pressure solution provider,
can provide a complete product line from equipment to accessories and consumables, and provide a full range of customized solutions.

Piston cylinder press can provide 4GPa high pressure,
1700℃ high temperature experimental environment

The automatic pressure holding device can evenly pressure and stabilize the
working pressure of the sample without manual duty.

Large chamber press,
The chamber is larger and the experiment is richer.

Kawai Large cavity press

The large press adopts Kawai type 6-8 two-stage pressure high temperature and high pressure device, and the open structure multi-lead measurement is more convenient. Using tungsten carbide anvil, high pressure >20Gpa and high temperature >2000°C can be generated on the sample.

  • ▪ Sample temperature >2000°C, sample pressure >20Gpa
  • ▪ The maximum tonnage of the press is 1000, 2000 tons
  • ▪ Press travel 150mm
  • ▪ Low pressure area, using traditional hydraulic system, high stability.
  • ▪ The high voltage range is regulated by the servo motor, and the maximum pressure error is +/-0.5 bar
