For aerospace, defence, and nuclear manufacturers, component integrity is a core requirement. Internal defects in cast or additive manufactured parts can reduce performance, shorten service life, and increase qualification risk**. Hot Isostatic Pressing (HIP)** helps address these risks by improving material density and reliability in critical components.

HIP uses high temperature and isostatic gas pressure to close internal voids and porosity, producing denser and more uniform materials. In castings, HIP reduces shrinkage porosity and internal defects that affect mechanical performance. In additive manufactured parts, HIP helps close internal pores and lack-of-fusion defects, improving fatigue properties and reducing the risk of in-service failure.

As a result, HIP extends component life, improves consistency, and helps de-risk critical applications where reliability is non-negotiable.

A Key Requirement for Mission-Critical Applications

The benefits of HIP are so significant that it is often specified as a mandatory process for aerospace, defence, and nuclear components. In many applications, HIP is required to meet qualification standards and ensure the material integrity needed for demanding operating environments.

HIP is routinely applied to high-performance materials such as titanium alloys, nickel-based superalloys including Inconel 718 and Inconel 625, stainless steels, and Hastelloy grades, where mechanical performance, fatigue resistance, and reliability are critical to component success.

As the use of advanced castings and additive manufacturing continues to grow, so too does the need for reliable HIP capacity.

Europe’s Largest and Most Modern HIP Capability

 

To meet increasing market demand, MTC Powder Solutions (MTC PS) has expanded its operations in Sweden with three HIP units, including one of Europe’s largest and most modern HIP vessels.

This investment significantly increases available HIP capacity within Europe while extending the size envelope of components that can be processed. Manufacturers can now access HIP treatment for larger and more complex parts, while benefiting from improved capacity and supply chain security.

More Than a HIP Service Provider

Many in the industry recognise MTC PS as a world leader in Powder Metallurgy Near Net Shape (PM NNS) HIP technology. The Swedish expansion also gives customers access to MTC PS as a HIP service partner for cast and additive manufactured components.

This not only gives customers access to world-class HIP equipment, but also to more than 40 years of experience working with HIP materials and processes.

That expertise creates a unique advantage. Beyond processing parts, MTC PS can support customers with material-related discussions, helping optimise component performance, qualification strategies, and manufacturing outcomes. Few HIP service providers can combine large-scale processing capacity with decades of hands-on experience in HIP-produced materials.

Supporting the Next Generation of Critical Components

As manufacturers continue to push the boundaries of casting and additive manufacturing, HIP remains a key enabling technology. By removing internal defects and improving material integrity, HIP helps ensure that components can meet the demanding requirements of aerospace, defence, nuclear, and other mission-critical industries.

With advanced HIP capability in Sweden, increased processing capacity, and decades of experience in HIP materials and manufacturing, MTC Powder Solutions is positioned to support customers that need reliable processing for critical cast and additive manufactured components.
