Introduction
Vacuum hot pressing furnace is a complete set of equipment that heats and pressurizes materials under vacuum or atmosphere. According to different materials and heating temperatures, heating elements can be graphite heater, molybdenum heater, and induction heating, etc; and one-way or two-way pressurization can be used for hydraulic pressurization.
Under the high temperature and high pressure and vacuum or atmosphere, the raw material solid particles are bonded with each other, the grains grow up, and the voids (pores) and grain boundaries gradually decrease;Through the transfer of materials, their total volume shrinks, and their density increases, becoming a compact polycrystalline sintered body with a specific microstructure, so that the materials can be pressed and formed.
The density, hardness and other mechanical, electronic and thermal properties of the finished materials can be significantly improved under high temperature and pressure as well as under vacuum or atmosphere

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
