Hot Isostatic Pressing (HIP) is a process that
uniquely combines pressure and temperature to produce materials and parts with
substantially better properties than
other methods. The pressure medium is an
inert gas, normally Argon. Low temperature and high isostatic pressure, up to
300 MPa (3000 bar/44,000 psi), yield better
controlled grain growth and
structure as well as isotropic properties, which result in the superior
performance characteristics typical for HIP'ed parts.
HIP applications include defect healing of
castings, consolidation of metal powder (pre-form and near-net shaped parts),
consolidation of ceramic powders, and
sintering of diamond tools.

Avure Technologies Isostatic presses are widely
recognized as the leading brand in the world. This is due to the Company's
technological superiority in a number of
areas, particularly in the
institutional knowledge related to engineering, design, manufacturing and the
application of high pressure. The first QUINTUS ® isostatic
press was
delivered in 1965.
AVURE offers a full line of standard models of
Hot Isostatic Presses for medium and large scale production or models can also
be custom configured to meet your
needs. These presses are available with
furnace diameters of up to 2 m (6.5 feet) for pressures ranging from 40 to 300 MPa (400 - 3,000 bar/6,000 - 44,000 psi)
and temperatures from 500 to 3,000 °C
(900-5400 °F).
