Cold Isostatic Pressing Ceramics

Cold isostatic pressing cip is a manufacturing process for the consolidation of metal and ceramic powders.

Cold isostatic pressing ceramics.

Isostatic pressing cold isostatic pressing consists in compacting a powder in an elastomeric container submersed in a fluid at a pressure of 20 to 400 mpa. Cold isostatic pressing allows the production of simple shaped small or large powder compacts up to 2000 kg with a uniform green density even for large. For metals around 100 theoretical density can be achieved while ceramic powders that are more difficult to compress can reach about 95 of theoretical density. For near net shaping and quality control of these materials a preform configuration of powder compact as well as density distribution and porosity structure must be investigated before sintering and subsequent processings.

Cip is used to consolidate metal and ceramic powders to make a green part that can be further treated i e. Hot isostatic pressing hip involves both temperature and pressure applied simultaneously to obtain fully dense. Cold isostatic pressing cip is conducted at room temperature. Medical implants tungsten carbide ceramics titanium and superalloys and aerospace parts.

A flexible commonly polyurethane mold immersed in a pressurized liquid medium commonly water is used in the cold isostatic pressing method see the scheme. Warm isostatic pressing wip differs from cip only in that shapes are pressed at warm temperature to about 100 c. For decades cold isostatic pressing cip has been used successfully by manufacturers around the world. Some of the products that go through ips are.

The cold isostatic pressing cip is a convenient tool to yield the powder compact of advanced materials including ceramics. Hot isostatic pressing hip and cold isostatic pressing cip technology has been known for more than 50 years and is considered today to be a standard production route for many applications. Froyen in fundamentals of metallurgy 2005. Isostatic pressing is the powder compaction method involving applying pressure from multiple directions through a liquid or gaseous medium surrounding the compacted part.

Isostatic pressing services ips is a toll hip company started in 2015 primarily to do toll hipping for the investment casting industry due to its prime location. Rolling machining or sintering.
