Hot & Cold Isostatic Pressing

AIP-AIP8-45H

Hot Isostatic Pressing (HIP) is used to reduce the porosity of metals and increase the density of many ceramic materials. 

Uses/applications

In powder metallurgy, HIP allows us to compress a volume of metal powder at such high temperatures and pressures, that through a combination of deformation, creep, and diffusion, you actually create a product with an homogenous annealed microstructure (compact solid) with minimal or no impurities in the materials. 

Detailed description

This is a key part of through-processing, from alloy design to component manufacture, and an essential process for aerospace components [for example]. The HIP has a 150mm diameter x 300mm long hot zone that is perfect for scaling up samples.

AIP-AIP3-12-60C

Cold Isostatic Pressing (CIP) is a process for the consolidation of powders.

Detailed description

This research CIP is used to shape form powders into a green body, prior to sintering. This model allows the pressing of various shapes, including discs, bars, and tubes, and is therefore a near-net-shape process. 

Detailed specifications

WORKING PRESSURE: 60,000 PSI
WORKING SIZE: 3" diameter x 12" long

Location

Royce Discovery Centre, Harry Brearley Building, 5 Portobello Street, Sheffield, S1 4ND
