What is Cold Isostatic Pressing?

With quality and productivity in focus

For decades, Cold Isostatic Pressing (CIP) has been used successfully by manufacturers around the world. CIP is used to consolidate metal- and ceramic powders to make a “green” part that can be further treated, i.e. rolling, machining or sintering.

With typical pressures from 1,035 to 4,138 bar (15,000 to 60,000 psi) and ambient temperature up to 93°C (200°F), CIP can achieve 95% of theoretical density for ceramics.

A proven process for high-performance parts

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 minimize wear of the cylinder heads, telecommunications, electronics, aerospace and automotive.

Cold Isostatic Pressing benefits

State of the art” technology for medium and large size CIP presses
  • Highest safety, i.e.,”Leak-before-burst”
  • Outstanding cyclic life (> 200,000 cycles)
  • Superior process control at all pressure levels
Benefits compared to conventional consolidation methods:
  • Programmable pressure distribution with good accuracy
  • Reduced mechanical stresses of processed materials
  • Lowest weight of the machine
New and unique materials can be processed
  • Process optimization
  • Improved functionality

Why you should CIP

60-95% of theoretical density
  • Consolidation of ceramic powders
  • “Green parts” for ceramics are ready for next process steps
  • Elaborate designs of ceramics by CIM (Ceramic Injection Molding)
Improved material properties
  • Increased mechanical properties e.g. powder compacts of alumina and electrical insulators
  • Reduced scatter of data for safest control of production
  • Highest properties for minimal corrosion deterioration
Safer and more efficient production
  • Fastest method for consolidation of ceramic powders to high density
  • Lowest cost/kg

We faced a colossal challenge! A cold isostatic press was needed to increase density of a 7,000 mm long part made from advanced materials. The CIP would need to fit into an existing manufacturing space, use existing overhead crane equipment, and have minimal impact on the existing structure.
