At Gasbarre, we produce isostatic presses that make powder metallurgy easier and more efficient than ever. 

What Are Isostatic Presses?

Isostatic pressing is a powder metallurgy process involving the application of equal pressure to a compacted powder to achieve optimal density and microstructure uniformity. Through this process, the press uses a gas or liquid to deliver force to a hermetically sealed container filled with the metal powder using either elevated or ambient temperatures. These processes are known as hot and cold isostatic pressing, respectively.

What Is Cold Isostatic Pressing?

Gasbarre isostatic presses are optimized for reliable cold dry bag isostatic pressing. Cold isostatic pressing involves the compaction of powders encased in elastomer molds. 

Through this process, the mold is placed into a pressure chamber and filled with a room-temperature liquid before the press applies the pressure from all sides, condensing the metal powder. As a result, the powder particles mechanically bond to each other, creating a solid green body. Finally, the liquid is removed and the container expands to its original form so that the product can be retrieved.

There are two types of presses used for cold dry bag isostatic pressing — monostatic isostatic presses with single-cavity structures and densomatic isostatic presses with multi-cavity designs.

Our Isostatic Presses for Powder Compaction

We carry reliable and innovative cold dry bag iso­static presses for powder compaction. Gasbarre’s SIMAC product line offers uniquely configured presses to allow for the laboratory or production manufacture of uniform density components. The dry bag design simplifies powder filling, compaction and ejec­tion and is more efficient, allowing for quick, ready-to-press parts.

SIMAC presses include a tool mounting system that allows for a wide range of parts to be produced in the same machine. Their dual inner bag configuration allows simple tool changeover.
