Technology & Products
Key Products
Wallwork Heat Treatment offers a comprehensive range of services including Hot Isostatic Pressing (HIP), vacuum heat treatment, nitriding (gas and plasma), PVD coatings (TiN, CrN), solution, age or precipitation, hardening and tempering, and vacuum brazing for metal AM parts.
Technological Advantage
Quintus QIH173L HIP with Uniform Rapid Cooling — most advanced HIP technology available — achieves precise microstructure control impossible with older HIP systems; unique combined HIP + heat treatment capability eliminates a second furnace cycle; four geographically distributed UK sites for rapid national logistics; 60+ years of aerospace process certification.
Differentiation
Value Proposition
Eliminates residual porosity and internal stress in metal AM components using the UK's most advanced HIP systems (Quintus QIH173L with Uniform Rapid Cooling), delivering aerospace-certified density and fatigue life improvements in a single integrated thermal processing step.
How They Differentiate
UK's largest private thermal processor with newest-generation Quintus HIP systems; unique combined HIP + heat treatment in single cycle saves time and cost; four 24/7 UK sites vs. competitors with single or fewer facilities; 60+ years of aerospace Nadcap-approved process heritage.
