CYLINDER LINER & SLEEVES
A-trac manufactures Cylinder Liners in gray cast iron using Centrifugal Casting. Special chemical compositions are also used to ensure corrosion resistance properties and enhanced lubrication. Centrifugal Casting Process is known to be the best method for manufacturing Cylinder Liners. In centrifugal casting, a permanent mould is rotated continuously about its axis at high speeds as the molten metal is poured. The centrifugal force causes the metal to distribute itself evenly around the die. The resulting casting is a fine-grained casting with a very fine-grained outer diameter, owing to chilling against the mould surface. Impurities and inclusions float to the surface of the inside diameter, which can be machined away.
Air Cooled Cylinder Liners are made from special “Shell Moulding Process” having wear resisting close grained iron casting to ensure long life and efficient cooling.
