Abstract

To produce a steel liner (10) for a cylinder (112) of an internal combustion engine, a tubular preform (50) of steel is subjected to a flow forming procedure which transforms it into a semi-finished liner (56) having a configuration that corresponds closely to the configuration desired for the cylinder liner. The flow forming process achieves a near-net shape such that only minimal amount of subsequent machining is required to transform the semi-finished liner (56) into the final shape for the cylinder liner (10).
