History

The number of foundries is falling as part of a domino-effect from the loss of the British steel industry.

 

Techniques

  • Sand casting – where a pattern, made of wood or original item is placed in a sand box, sand rammed around it, the pattern removed and molten brass poured into the cavity. This includes bell founding.
  • Investment casting or lost wax – where a pattern is moulded in rubber, wax  facsimiles are formed from the mould, these facsimiles may be joined if there are many small ones in the form of a ‘tree’ inside a flask or, if the object is large a  form is made and  that is then filled with plaster. The flask is then heated in a kiln, the wax is melted out (lost) and molten metal is poured, sometimes under vacuum, into the cavities that remain in the flask
  • Shell casting – where the wax facsimile is dipped numerous times into a slurry until a shell is built up rather like battering fish. Once the shell has dried then the  wax is melted out and molten metal poured into the empty shell(s).
  • Die casting – where a negative of the desired finished object is engineered in metal and then injected with molten metal.
