Traditional materials and manufacturing methods have kept the door open to problems associated with thermal stress fracturing or simply put, cracking. This phenomenon is primarily focused on the use of gray irons and particularly individual mold casting. That process creates difficult to control porosity problems during the casting procedure. Porosity weakens the structure and reliability suffers. We address this core issue in several areas by spec¡¯ing high grade Ductile Iron, not Gray iron. Then using a computer controlled continuous cast process to produce high quality heat treated iron ingots (giant bars, often referred to as billet). These are then cut into plates with highly specialized saws and CNC machined. The rotors are double disk ground to a tight tolerance and finish to insure flatness and parallelism. This material and method eliminates porosity, creates a homogenous and consistent grain matrix structure that is both very stable and very strong.
