Vacuum Hot-Press Sintering Furnace
Vacuum hot pressing furnaces are mainly used by colleges and universities, scientific research institutions, and other institutions for hot pressing and sintering of inorganic materials, cemented carbides, functional ceramics, powder metallurgy, etc. under high temperature and vacuum conditions, as well as for testing the sintering performance of small samples. They can increase the density of materials and can also be used for hot pressing and sintering under gas protection.

Structural features of
Vacuum Hot Pressing Furnace
Starting from the internal structure, we show you the unique design logic of vacuum hot pressing furnace products:
-
Chamber and heating
Below 1200℃, use resistance wire module for heating
Above 1200℃, use graphite heating element
-
Ranging system
The distance is measured by grating ruler, with high precision, the accuracy can reach 0.02mm.
-
Temperature measurement system
Tungsten-rhenium thermocouples are used at low temperatures, while infrared thermometers are used at high temperatures.
Tungsten-rhenium thermocouples automatically shut down at high temperatures.
-
Control system
PLC+touch screen.
The equipment's operating conditions, temperature, vacuum degree, and displacement data curves can be recorded and viewed at any time.

FAQ
Focus on answering common questions to provide users with clear and practical usage guidelines:
-
Q:What is the pressure range and control accuracy?
A:The pressure range is adjustable up to 5 tons. High quality equipment offers even higher precision, enabling precise control of pressure changes.
-
Q:Can process data be recorded and exported in real time?
A:Full-process data recording includes temperature, pressure, vacuum level, displacement, and more. Data curves can be exported for easy process traceability and analysis.
-
Q:How to define the hot pressing time for different materials?
A:This depends on the difficulty of densifying the material. Powder metallurgy parts typically require 30-60 minutes, while ceramic composites may require 2-4 hours to ensure sufficient pressure transfer to the interior and eliminate porosity.
