Featured Success Story
Anders Johansson
VP Procurement, Nordic Thermal AB
Scaled from Prototype to 50,000 Brazed Heat Exchangers in 10 Weeks
TigerHubs took our complex plate-fin heat exchanger from CAD to full production faster than any supplier we have worked with. Their DFM feedback caught potential braze flow issues before fixturing, saving us thousands. Zero leaks on 100% helium testing across all 50,000 units.
Heat exchanger brazing batch at TigerHubs
"We switched to TigerHubs for our heat exchanger brazing after struggling with leak rates from our previous supplier. Their vacuum brazing process achieved helium leak rates below 1E-9 mbar-L/s on every single unit."
James Mitchell
CTO, ThermaCool Systems (USA)
"As an aerospace supplier, we require NADCAP-compliant brazing. TigerHubs brazing of our Inconel fuel nozzles was flawless with perfect capillary flow and zero voids on X-ray inspection."
Dr. Elena Rossi
R&D Director, AeroBraze S.p.A. (Italy)
"We have sourced brazed assemblies from China for over a decade. TigerHubs stands out for their transparency, real-time batch tracking, honest lead times, and exceptional braze quality."
