Hot Isostatic Presses

Hot Isostatic Presses - Basic functions

ABRA Fluid, one of the largest manufacturers of Hot & Cold Isostatic Presses introduces its Hot Isostatic Press Production Unit (HIP). Hot Isostatic Presses serve to produce workpieces without weak spots or welding cracks, but with optimal weight, best material property and long product life. By Hot Isostatic Pressing such workpieces can be manufactured with low costs and especially time efficient.
Hot Isostatic Pressing is a heat treatment process which occurs by using high pressures (usually up to 2’000°C and 200 MPa pressure). In order to reach the required workpiece specifications the cast parts are heated in argon atmosphere with all side effective gas pressure and high temperatures beneath their flow limit, so that diffusion controlled creep processes set in and lead to densification. Through this process internal cavities and residual porosity are removed from cast or sintered workpieces. Also like this various materials in either solid or powder metallurgically form can be merged with each other or applied as coating. Powder metallurgically materials can be compressed down to their theoretical density. After this they show characteristics which could have never been reached in the usual melting metallurgical way.

Research and application fields of Hot Isostatic Presses:

punkt    Research of optimal carbide components used in mass-production of parts (machined and wearing parts industry) such as indexable inserts, scalpels, core bits etc.

punkt    Research of ceramic alloys for medical components such as dental technology and artificial joints for the human musculoskeletal apparatus; highly wear resistant parts such as ball bearings and rolls etc.

punkt    Research and manufacturing of high temperature steels

punkt    Research of superconducting basic materials

This listing is not terminatory but shows the most important application fields.

Hot Isostatic Pressing Services at our own HIP

Customers are offered Hot Isostatic Pressing Services at our in-house Hot Isostatic Press.

We can offer the following specifications:

punkt    in operating pressure range up to 200 MPa

punkt    in temperature range up to 2’000°C

This offer is often used by smaller universities or companies who want to avoid the fixed costs of operating an own Hot Isostatic Press or are standing at the beginning of a series of tests. Our process engineers will be happy to advise you in this matter.
