Sand moulding systems use sand as a refractory material and a binder that maintains the shape of the mould during pouring. A wide range of sand/binder. Cleaner Production Manual for the Queensland Foundry Industry November 1999 Page 7 systems are used. Green (wet) sand systems, the most common sand system, use bentonite clay as the binder, which typically makes up between 4% .
· Shaping styrofoam. Styrofoam is one of the easiest materials to shape by normal means slicing with sharp knives or a hotwire cutter, sawing with serrated blades, rasping with files, and smoothing with sandpaper. The real challenge lies in controlling the shape and especially, in this case, how one achieves concave forms.
Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (, a threedimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue.
Zircon sand flours. Zirconium silie or Zircon is a naturally occurring sand. Zircon's low thermal expansion rate, its high thermal conductivity and its nonwettability by molten metal make it an ideal mould and chill sand. Zircon is also used in core and .
