Powder metallurgy rapid omnidirectional compaction and slurry casting technology

Powder metallurgy rapid omnidirectional compaction and slurry casting technology

The powder metallurgy rapid omnidirectional pressing and slurry casting molding technology is the knowledge brought to us today. Whether it is the engine parts of cars, compressor parts, tailgate parts, etc., are all made by powder metallurgy technology. In addition to cars, there are many equipment that also need powder metallurgy technology, which has many advantages over traditional processing, Now let's take a look at powder metallurgy rapid omnidirectional compaction and slurry casting technology.

Powder metallurgy rapid omnidirectional compaction technology

It is a new technology for densification of powder materials. It is a cheap process for consolidating high-performance pre-alloy powder into fully dense parts. Compared with hot isostatic pressing (HIP), ROC has the advantages of high and low temperature, and can accurately control the size of products. The performance can at least reach the level of isostatic pressure, the production cost is 50% of HIP, and the consolidation speed is faster than HIP.

Powder metallurgy slurry casting technology

It is a molding technology that has been used in the ceramic industry for more than 200 years. In the middle of the 20th century, metal powder, carbide, nitride, boride, hard alloy, stainless steel, etc. were prepared by slurry casting.

The basic process of the slurry casting process is to make powder and water (or other liquids, such as glycerin, alcohol, etc.) into a certain concentration of suspension slurry, and inject it into the gypsum mold with the required shape. The porous gypsum mold absorbs the water (or liquid) in the slurry, so that the slurry material can be compacted in the mold and form the corresponding molding injection part on the mold surface. After the gypsum mold absorbs the liquid in the slurry, the mold can be removed to take out the injection part.
