Application of exhaust core bone in the production of water-cooled exhaust manifold

This article explores the influence of the number and position of process holes on the casting performance of water-cooled exhaust manifolds.The use of a new type of dual purpose core bone for exhaust and support has solved casting defects such as core breakage,choking,and peeling in water jacket products with fewer process holes,ensured the production of castings,improved the casting yield of water jacket products,gained customer recognition,and achieved good results.
