Difference Between Hot Isostatic Pressing and Hot Pressing

The hot isostatic pressure densification process is to place the product in a closed container, input high-pressure argon into the container through a compressor, and heat it through the heating furnace in the container at the same time, so that the product can be densified under the action of high temperature and high pressure at the same time.

What is the difference between hot isostatic pressing and hot pressing
Pressurization method and density distribution of the product
The main difference between hot isostatic pressing and hot pressing is the pressurization method and the density distribution of the product.
Pressurization method: Hot pressing usually applies pressure through a single axis, which means that the pressure acts mainly in one direction, while hot isostatic pressure is applied by equal pressure in all directions, i.e., the pressure is equal in all directions. This difference allows HIP to act uniformly on the material in three-dimensional space, while HIP is mainly concentrated in a single direction. 1
Product density distribution: Since hot pressing mainly relies on uniaxial pressure, the density distribution of products may be uneven, while hot isostatic pressing can make the density of products basically consistent due to the application of equal pressure in all directions.
These differences make HIP more suitable for applications that require uniform densification, such as densification of ceramic materials, preparation of high-performance metal materials, etc.
