The long-term stable operating temperature can reach 1550℃, with a temperature control accuracy of ±1℃. The pressure range is 0.5～150 tons, which can meet the hot pressing sintering requirements of different materials.

The equipment supports multiple atmosphere environments such as vacuum, nitrogen, hydrogen, argon, carbon monoxide, and oxygen, and is equipped with automatic/manual pressure regulation, constant pressure holding, digital data storage, and multi-segment program temperature control functions.

Product Features

1. Precision Hydraulic Automatic Constant Pressure, Pressure Accuracy ±1‰

Utilizes an electric precision hydraulic press, with pressures customizable from 0.5 to 150 tons. Pressure adjustment is digitally displayed automatically/manually, supporting programmable curve control with an accuracy of ±1‰. Equipped with imported solenoid valves, ensuring excellent pressure holding and constant pressure accuracy of ±1‰. Pressure and temperature change data are digitally stored and recorded, and can be exported to spreadsheets for complete process data traceability.

2. Adjustable Bottom Mechanism for Flat Pressure Distribution

Equipped with a bottom adjustable mechanism, effectively ensuring the flatness of the pressure head and base, guaranteeing uniform pressure distribution on the sample surface. This avoids sample deformation and density differences caused by uneven pressure, improving the consistency of hot-pressed product quality.

3. Dual-Use Vacuum and Atmosphere Functionality, Multi-Atmosphere Compatibility

Vacuum level up to -0.1 MPa, compatible with various gases such as hydrogen, nitrogen, argon, carbon monoxide, and oxygen. Employs two float flow meters (nitrogen/hydrogen) for precise gas flow control. Vacuum and atmospheric conditions can be freely switched to meet the stringent atmospheric requirements of different materials.

5. Integrated PLC Control + Dual-Circuit Protection

The system employs an integrated modular control unit and PLC control, ensuring accurate control precision. It features dual-circuit control and dual-circuit protection, providing comprehensive protection against overshoot, over-adjustment, under-adjustment, thermocouple breakage, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start.
