Precision sand casting aluminum parts

The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, or carved directly into the sand.
Sand casting is the most widely used method employed in foundry. In this process, sand moulds are contained in metal molding boxes (or `flask`) that have four sides but no top or bottom below. During the molding operation the boxes are located together by pins so that they can be separated to remove the pattern, and replaced in the correct position before the metal is poured in. The boxes are clamped together, or the cope (top section) weighted down when pouring to prevent the cope from `floating away` from the drag (lower section) when the mould is full of molten meta
Sand casting is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). The processes of sand casting are discussed in this section, include patterns, sprues and runners, design considerations, and casting allowance.

Basic process
There are six steps in this process:
1.Place a pattern in sand to create a mold.
2.Incorporate the pattern and sand in a gating system.
3.Remove the pattern.
4.Fill the mold cavity with molten metal.
5.Allow the metal to cool.
6.Break away the sand mold and remove the casting.
