Manufacturing process
The process on which the project will intervene can be depicted as follows:

  • Melting: takes place in a cupola furnace, with layers of coke and ignited with torches. When the coke is ignited, air is introduced to the coke bed through tuyeres in the sides, and when the coke is very hot, solid pieces of metal are charged into the furnace. The metal is alternated with additional layers of fresh coke.
  • Moulding: every day the production plan is sent to the molding line, and the parts to be cast during the day are indicated, with emergencies specified. The actual process of moulding is implemented by exploiting the imprint left by the two halves of the pattern on the green sand that fills the lower and upper box.
  • Pouring: the shapes are placed on the pouring line ready to be filled with molten iron.
  • Castings: the molten iron is cast and take the shape needed
  • Shot blasting: is performed to clean and polish castings, after being deprived of risers, investing them with a jet of steel shot.
  • Finishing: the castings are painted and polished.
