We manufacturer air cooled block for which casting is done in graded grey cast iron in such a way so as to achieve paralytic structure free from ferrite and graphitic as per international standards. Air cooled block are cast by shell molding process & used for diesel engines, automobile engines. The casting of these air cooled blocks/barrels are machined in the machine ship equipped with precision CNC turning centr, hydraulically operated NC controlled honing machines. We maintain hardness of the cylinder barrels strictly as per international standard. The usage of hardned liners with plateau finish improves the engine life, lowers lube oil consumption and improves fuel efficiency.
