How a cylinder liner is made?

A cylinder liner is typically made through a process called casting, where molten metal is poured into a mold shaped like the liner. Common materials include cast iron or aluminum alloys, which provide the necessary strength and durability. After cooling, the liner undergoes machining processes such as boring and honing to achieve precise dimensions and a smooth surface finish. Finally, quality control checks ensure that the liner meets specifications for performance and durability in an engine.
