Stable & reliable DC power supply
09 March 2015
Selmet Inc., an American supplier of titanium investment casting to to the global aerospace industry has purchased 4 x 10,000 Amp, 0-35 Volt Cortina rectifier sets formerly used in the UK for the anodising of surface finished aluminium coil, as used in light diffusers and other similar products, from Riley Surface World. These high powered units are now being applied to vacuum arc melting (VAR).
Vacuum arc melting (VAR) is a method of melting consumable titanium electrodes in a water-cooled copper crucible while under a vacuum using high amperage and low voltage.
This highly specialised process requires a stable and reliable DC power supply, something that Riley Surface World was able to provide at a greatly reduced price in comparison to the purchase of new equipment.
