CENTRIFUGAL CAST PROCESS is acknowledged to be the best method for manufacture of Cylinder
Liners. It possesses the bearing metal qualities that cause skin healing after abrasion and a structure
that is readily wetted by oil and retains an oil film. Corrosion resistance is further improved by adding
Chromium to the metal. In the centrifugal casting process, the molten metal is poured into a metal
mould or die, which is revolving at a high speed. The centrifugal force causes the metal to distribute
itself evenly around the die. The resulting casting is of much finer grain and free from blow holes or
porosity. A further important advantage is that the impurities, being lighter than the iron, are forced
centrifugally to the bore surface from which they are removed by machining.
