Similarities and differences between vacuum hot pressing sintering furnace and vacuum sintering furnace

Similarities:

1. Vacuum environment: Both furnaces can provide a vacuum environment, which can exclude oxygen and other impurities to ensure the purity of the material during the sintering process.

2. High temperature sintering: Both furnaces can provide high temperature conditions for the combination and densification of materials.

The difference:

1. Pressure: In addition to providing a vacuum environment, the vacuum hot pressing sintering furnace can also apply pressure. The vacuum sintering furnace only provides a vacuum environment and does not apply additional pressure. The density and mechanical properties of sintered body can be further improved by applying pressure in vacuum hot pressing sintering furnace.

2. Application: Vacuum hot pressing sintering furnace is mainly used in the sintering of high-performance ceramics, cemented carbide and other materials, as well as powder metallurgy, composite materials and other fields. Vacuum sintering furnace is more widely used in the sintering of various materials, including ceramics, metals, magnetic materials and so on.

3. Equipment structure: Because the vacuum hot pressing sintering furnace needs to apply pressure, its equipment structure is usually more complex than the vacuum sintering furnace. Vacuum hot pressing sintering furnace usually includes pressure system, heating system and vacuum system. The vacuum sintering furnace is relatively simple, mainly including heating system and vacuum system.

In summary, the vacuum hot pressing sintering furnace and the vacuum sintering furnace are the same in providing a vacuum environment and high temperature sintering, but the vacuum hot pressing sintering furnace can apply pressure
