IMPROVE YOUR FOUNDRY PROCESSES
AN INTEGRATED APPROACH
TO HELP YOU IMPROVE
YOUR PERFORMANCE
KALTEK* ladle lining systems are just one
example of a long list of innovations that
Foseco has developed and commercialized
& K7 c' E/ g% Isince we began helping foundries in
1932. Our ability to help your foundry
succeed comes from our comprehensive
knowledge of the foundry business and
