Machining new tooling for COPVs

Tooling has started here in Australia for the manufacturing of our ~1000L Type IV H2 pressure vessels. They will hold ~24 kg of compressed hydrogen at 350 Bar. The 450kg (990 lb) aluminium block (810mm diameter) is machined on our Okuma 5-axis CNC machine to make the dome end. That’s a lot of chips!
