Double Control System Vacuum Sintering Furnace , 6MPa HIP Metal Sintering Machine
6MPa Vacuum pressure sintering furnace
The application field of vacuum pressure sintering furnace:
The purpose of the vacuum pressure sintering furnace is manufacturing of cemented carbide tools by the removal of adhesive from pressed forms, solid-phase sintering in vacuum and protective atmosphere (argon, hydrogen) and sintering in the presence of liquid phase with application of pressure.
1. All these gas pressure sintering furnace are equipped with double control system, double thermocouples and double high pressure sensor to ensure that if one system fails, the other will continue to work reliably.
2. We use German COAX high-pressure valve, Germany WAKI high-pressure sensor and Germany LEYBOLD or INFICON vacuum gauge for safe and reliable operation, high vacuum level and low vacuum leakage.
3. Each of these 6MPa vacuum-pressure sintering furnaces is detected by using helium mass spectrometer leak detector.
