What is a Cold Isostatic Press? (5 Key Points Explained)

Cold isostatic pressing (CIP) is a method used to compact powdered materials at room temperature, typically below 93°C.

It uses a liquid medium as the pressure medium and rubber or plastic as the encasing mold material.

The process involves applying pressure from multiple directions.

This results in greater uniformity of compaction and increased shape capability compared to uniaxial pressing.

This technique is primarily used to create "raw" parts with sufficient strength for handling and further processing, such as sintering or hot isostatic pressing.

What is a Cold Isostatic Press? (5 Key Points Explained)

1. Two Main Methods of Cold Isostatic Pressing

There are two main methods of cold isostatic pressing: wet-bag and dry-bag.

In wet-bag isostatic pressing, the powder is encased in a rubber sheath that is immersed in a liquid.

This liquid transmits the pressure uniformly to the powder.

In contrast, dry-bag isostatic pressing involves building the tooling with internal channels into which high-pressure fluid is pumped, rather than immersing the tooling in a fluid.

2. Advantages of Cold Isostatic Pressing

Cold isostatic pressing is particularly advantageous for producing parts with complex shapes or very large compacts.

It is also suitable for a variety of powders, including metals, ceramics, plastics, and composites.

The pressures required for compacting range from less than 5,000 psi to more than 100,000 psi (34.5 to 690 MPa).

3. Common Applications of Cold Isostatic Pressing

Common applications include the consolidation of ceramic powders, graphite, refractory materials, electrical insulators, and the compression of advanced ceramics such as silicon nitride, silicon carbide, boron nitride, boron carbide, titanium boride, and spinel.

The technology is also expanding into new applications, such as the compression of sputtering targets and the coating of valve components used to reduce cylinder wear in engines.

4. Versatility and Effectiveness

Cold isostatic pressing is a versatile and effective method for compacting powdered materials at room temperature.

It uses a liquid medium and rubber or plastic molds.

It offers advantages in terms of shape capability and uniformity of compaction.

5. Suitable for Various Industries

This method is suitable for a wide range of applications in various industries.
