It is to be expected that the Rules wil one day be taken as an outline or blueprint for an international specification on the methods for making reliable castings.John Cambell has over two decades of experience in the casting industry and is the author of over 40 technical papers and patents. He has become well-known in the foundry industry as the originator of the Cosworth casting process, which is becoming accepted throughout the world as a new production process for the casting 606 $aFounding 606 $aMetal castings 615 0$aFounding. 615 0$aMetal castings. 676 $a671.2 700 $aCampbell$b John$cMAFS.$0627327 701 $aCampbell$b John$cMAFS.$0627327 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910784332203321 996 $aCastings practice$91212912 997 $aUNINA
