TTT Brings HIP Post-Processing In-House

Spanish surface-coatings subcontractor TTT Group is bringing hot isostatic pressing into its own production chain with a Hiperbaric HIP 107 system. The investment extends the company beyond coating operations and gives it direct control over a thermal and pressure treatment increasingly important to high-value metal parts.

HIP exposes components to elevated temperature and uniform gas pressure, closing internal pores and improving the consistency of mechanical performance without changing a part's overall geometry. That makes the process especially relevant to additive manufacturing, where complex shapes can be produced efficiently but hidden porosity may still limit fatigue life or qualification.

TTT is targeting aerospace and oil-and-gas work, sectors in which material integrity and documented process control carry more weight than build speed alone. Installing the equipment in-house can shorten logistics between manufacturing, densification, coating and inspection while giving engineers a tighter view of the complete post-processing route.

The purchase also reflects a broader industrial shift: additive production capacity is being matched with finishing and property-enhancement infrastructure. For demanding metal applications, the printed shape is only the beginning; repeatable downstream treatment is what turns it into a certifiable component.
