Another approach to iron casting: the permanent mold process
The ferrous permanent mold (FPM) process which was patented by Eaton Corp. in 1932 is widely used accepted overseas, although the mold was born on U.S. soil. The FPM casting process is predominantly a mass-production method that becomes cost-effective only when used for properly selected parts. Matched with the proper casting design, there are definite advantages in cost, quality, energy reduction and environmental issues.
