What are the types of vacuum sintering furnaces?

Vacuum sintering furnaces can be classified into various types according to different classification standards. Here are some main classification methods and corresponding types:

1. Classified by temperature range
Ordinary sintering furnace: suitable for temperature ranges of 1300 ℃ and below.
Medium temperature sintering furnace: suitable for a temperature range of 1300 ℃~1600 ℃.
High temperature sintering furnace: suitable for a temperature range of 1600 ℃~2400 ℃. In high-temperature sintering furnaces, graphite tubes, tungsten metal, etc. are often used as heating elements, or induction heating is used.

2. Classified by vacuum degree
Low vacuum sintering furnace: The vacuum degree is relatively low.
High vacuum sintering furnace: With high vacuum degree, it can meet the sintering process with high requirements for vacuum degree.
Ultra high vacuum sintering furnace: The vacuum degree reaches a very high level and is usually used in scientific research and production fields that have extremely strict requirements for vacuum environment.

3. Classified by structural form
Horizontal vacuum sintering furnace: The furnace body is arranged horizontally, suitable for processing long or large workpieces.
Vertical vacuum sintering furnace: The furnace body is arranged vertically, occupying relatively small space and easy to operate.
Box type vacuum sintering furnace: The furnace body has a box shaped structure, suitable for processing small workpieces or batch sintering.

4. Classify by other characteristics
Vacuum hot pressing sintering furnace: performs hot pressing sintering in a vacuum environment, suitable for workpieces that require pressure during the sintering process.
Atmosphere protection vacuum sintering furnace: In a vacuum environment, inert gas or other protective atmospheres are introduced for sintering to prevent oxidation of the workpiece during the sintering process.

In summary, there are various types of vacuum sintering furnaces, and users can choose the appropriate type based on specific process requirements, workpiece characteristics, and equipment conditions. When choosing, it is necessary to comprehensively consider factors such as heating method, temperature range, vacuum degree, structural form, and other characteristics.
