Applications
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
Advantages
- Hot pressing sintering of metal and ceramic powders;
- Preparation of ceramic/metal composites and intermetallic compounds;
- Research and development of diffusion welding process;
- Densification hot press sintering of oxygen/nitrogen/boron/carbon compounds and their mixtures
Detail & Parts
- Double shell structure with water-cooled jacket, the inner shell is made of stainless steel and has been finely polished. Housings are high quality carbon steel with anti-rust treatment or stainless steel with pad blasting.
- The heating element adopts graphite or molybdenum wire. Heating is divided into 1-phase or 3-phase heating. The rational design of the heating element helps to improve the uniformity of the temperature in the cavity.
- The furnace can be easily operated through the electrical control system. The temperature and pressure are controlled by PLC analog, or the sintering process is automatically completed by using a temperature and pressure programmable controller. The control system has alarm and protection functions such as water cut off, over temperature and over current.
Structure introduction
This electric furnace has two types of graphite heating and resistance wire heating, which are suitable for sintering metal powder, inorganic non-metallic materials, etc. under vacuum and high temperature hot pressing; of course, hot pressing sintering can also be carried out under protective atmosphere. In this way, the densification of the material can be completed, deformation can be prevented, and the grain size of the nanopowder can be suppressed.

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.
