    摘要： A method and apparatus for making engine cylinders comprising the steps of punching cylindrical tubes with openings from the inside to the outside and then surrounding the thus formed tubes with a different body of material. In accordance with the method, the punching apparatus includes a mandrel that slidably supports the dies and a backup die that includes a slug ejecting punch which serves the dual function of ejecting the slugs from the backup die and also retracting the punches. In one embodiment of the invention, the port openings are formed smaller than the final configuration and the surrounding material is cast in place and extends into the liner opening for interlocking the surrounding material to the liner.

    摘要： An iron casting, such as a cylinder block for an internal combustion engine, includes a number of component zones, with each of the zones having selected surface to volume ratio and selected section thickness sufficient to cause in-mold cooling during the casting process at controllable, but varying rates sufficient to result in predetermined, different percentages of nodular and compacted graphite iron in at least two of the zones of the cylinder block or other iron casting.
