The hip process applies high pressure 50 200 mpa and high temperature 400 2 000 c to the exterior surface of parts via an inert gas e g argon or nitrogen.
Cold isostatic pressing ceramics.
Cold isostatic pressing cip is applied to consolidate ceramic or refractory powders loaded into elastomeric bags.
Cip is used to consolidate metal and ceramic powders to make a green part that can be further treated i e.
Common applications for cold isostatic pressing include consolidation of ceramic powders compressing of graphite refractories and electrical insulators and other fine ceramics for dental and medical applications the technology is expanding into new applications such as pressing of sputtering targets coatings of valve parts in an engine to.
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.
Medical implants tungsten carbide ceramics titanium and superalloys and aerospace parts.
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 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.
Cold isostatic pressing cip is a manufacturing process for the consolidation of metal and ceramic powders.
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.
Hot isostatic pressing hip involves both temperature and pressure applied simultaneously to obtain fully dense.
Some of the products that go through ips are.
Rolling machining or sintering.
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.
Froyen in fundamentals of metallurgy 2005.
Cold isostatic pressing cip is conducted at room temperature.
Isostatic pressing is the powder compaction method involving applying pressure from multiple directions through a liquid or gaseous medium surrounding the compacted part.
The cold isostatic pressing cip is a convenient tool to yield the powder compact of advanced materials including ceramics.
Warm isostatic pressing wip differs from cip only in that shapes are pressed at warm temperature to about 100 c.
