Introduction to Isostatic Pressing

Isostatic pressing is a manufacturing process that involves applying uniform pressure to a material to achieve a specific shape or density. The process can be performed at room temperature (cold isostatic pressing or CIP) or at high temperatures (hot isostatic pressing or HIP). This technique is widely used in the production of ceramics and refractory materials, and offers several advantages over other manufacturing processes, including improved mechanical and wear/corrosion properties, flexibility in shape and size, and enhanced alloying possibilities. Isostatic pressing also offers predictability and consistency in the final product, making it a popular choice for a range of industries.

Cold Isostatic Pressing (CIP)

Cold isostatic pressing (CIP) is a manufacturing process that involves compressing a powder or slurry into a desired shape by applying equal pressure from all sides. It is a method of compacting powdered materials into a solid homogeneous mass before machining or sintering. This technique ensures that materials have a uniform density, which means that there will be uniform shrinkage when the material is going through other processes such as sintering.

Types of Cold Isostatic Pressing

There are two types of cold isostatic pressing currently recognized all over the world.

Wet Bag Technology

In this process, the powder is filled in a mold and sealed tightly. After filling the mold with powder, the mold is submerged in the pressure fluid within the pressure vessel. Then isostatic pressure is applied to the external surface of the mold, compressing the powder into a solid mass. This process is not as common as the other type of cold isostatic pressing.

Dry Bag Technology

In this process, the mold is fixed in the pressure vessel. The powder is filled in the mold while it is still in the pressure vessel. After this, isostatic pressure from the pressure liquid is applied to the external surface of the mold, compressing the powder into a solid mass with a compact microstructure. Dry bag technology is ideal for the mass production of materials.

Advantages of Cold Isostatic Pressing

One of the benefits of using cold isostatic pressing in manufacturing is the ability to produce products with precise dimensions and uniform density. Additionally, CIP can be used with a variety of materials, including ceramics, metals, and polymers. This versatility makes it an ideal choice for many industries, such as aerospace, automotive, and medical.

Cold isostatic pressing also has the advantage of being a non-destructive process, allowing for the reuse of materials and reducing waste. Furthermore, it can be used to produce products with improved strength, durability, and resistance to wear and tear.

Compared with manual CIP, the electrical CIP can deliver better pressure control. Die-wall friction, which exerts a major influence on the density distribution of cold-pressed parts, is absent; so much more uniform densities are obtained. The elimination of die-wall lubricants also permits higher pressed densities and eliminates problems associated with lubricant removal prior to or during final sintering.

Because of the uniform compaction pressure, the cross section-to-height ratio of the part is not a limiting factor as it is with uniaxial pressing. In addition, cold isostatic pressing can be used to compact more complex shapes than possible with uniaxial pressing.

Isostatic pressing is a powder metallurgy (PM) forming process that applies equal pressure in all directions on a powder compact thus achieving maximum uniformity of density and microstructure without the geometrical limitations of uniaxial pressing.

Hot isostatic pressing (HIP)

Hot isostatic pressing (HIP) is a manufacturing process that applies high temperature and pressure to materials such as metals and ceramics to improve their mechanical properties. The process is performed in a pressure vessel inside a high-temperature furnace, where parts are loaded and heated, pressurized with an inert gas such as argon, and held at this temperature and pressure for a specified amount of time. The heat and pressure are applied evenly to the part, forcing out porosity and creating a uniform microstructure in the material, which can improve properties.

How does HIPing work?

HIPing takes place in a pressure vessel inside a high-temperature furnace. Parts are loaded into the chamber which is then heated, pressurized with an inert gas such as argon, and held at this temperature and pressure for a specified amount of time. The heat and pressure are applied evenly to the part (isotropically), forcing out porosity. The HIPing process can also include pressurized rapid cooling, which functions as a quenching step. HIP cycles can take 8 to 12 hours or longer.

Benefits of HIP

Hot isostatic pressing (HIP) has numerous benefits in manufacturing. The process can create materials with superior mechanical properties, such as increased strength and toughness, due to the high pressure and temperature conditions during HIP that can cause the material to become more dense and uniform in structure. Additionally, HIP can be used to create complex shapes and designs that cannot be achieved through other manufacturing processes. This technique has also been shown to improve the fatigue life of materials, which is essential for products that are subject to repeated loading and unloading.

HIPing of 3D printed parts

HIPing is now used for post-processing of metal 3D printed parts, typically those produced by powder bed-based processes such as laser powder bed fusion (LPBF) and binder jetting, although directed energy deposition (DED) parts are sometimes also Processed this way. The printed parts are loaded into baskets and transferred to the chamber of the HIP furnace. The HIPing process can also include quenching, aging and other post-processing steps.

Application of HIP in manufacturing industry

Hot isostatic pressing (HIP) is a well-established process used to improve various materials such as titanium, steel, aluminum and high-temperature alloys. Using this process, voids within the casting can be reduced or eliminated, and the encapsulated powder can be combined to form a fully dense material. HIPing can reduce quality assurance inspection requirements by improving material properties and reducing performance dispersion. Often, the savings on radiography will pay for the HIP. Optimized material properties can be established to minimize subsequent heat treatment requirements. Machined parts have higher reliability and longer service life.

In summary, hot isostatic pressing (HIP) is an efficient manufacturing technology that produces high-quality materials with excellent strength and durability. The HIP process is widely used in the aerospace, medical and automotive industries due to its numerous advantages. The use of HIP can create materials with superior mechanical properties, such as increased strength and toughness, and can be used to create complex shapes and designs not possible through other manufacturing processes. HIPing has many benefits in manufacturing and can reduce quality assurance inspection requirements by improving material performance and extending service life.
