Abstract The production method of cast-iron diesel engine cylinder jacket includes the processes of making blank, machining-forming and plasma beam scanning and quenching, and is characterized by adopting polystyrene foam plastics and making it foam in cylinder jacket mould to form a dissolvable mould with cylinder jacket shape, applying alloy penetrating agent and fire-proof coating, embedding it into molding box, sealing and evacuating, pouring molten iton while evacuating and condensing so as to obtain the invented blank. As compared with the centrifugal casting process, the cylinder jacket blank produced by said invented method is light in weight, has no casting inner stress, its internal and external structure is compact and uniform, its production cost is low and wear-resisting property is good.
