              5.0.4   Die casting

              The  mould  is  of  steel  in  several  parts  dowelled
              together. Molten metal is fed by  gravity or pressure
              and, when solid, is ejected by pins. Aluminium, copper,
              manganese and zinc alloy are suitable for casting by
              this method.

                                                          Cylindrical or  circular  components  such  as piston
                                                          rings, cylinder liners, pipes,  etc.,  may  be  cast  in  a
                                                          rotating mould. Centrifugal pressure gives a fine grain
                                                          casting. Any metal may be cast using this process.
