Aluminium sand casting

    Aluminium sand casting is one of the oldest casting process in the world, its history seems more thousands of years. It is characterized by using Aluminium and its alloy as casting material and using sand as the mould material. And this process also called Aluminium sand molded casting.
    Although the Aluminium sand casting also have its limitation, such as lower dimension accuracy, pattern maintenance difficulties, rougher surface, but it is still widely be used today.
    Why Aluminium sand casting so old but still wildly used today? It is just because Aluminium sand casting have its advantages as below list:

1.     Wide-spectrum for material choosing: can be readily produced in nearly any of Aluminium alloys, including low-silicon Aluminium alloy which can’t be done by other casting process.
2.     2.Low tooling cost: The relatively low cost of tooling makes sand casting a process of choice for lower volume needs.
3.     3. Versatile apply for size, weight, shape: Sand castings can be produced in weights from grams to tons. Via using cores, internal structures can be cast in place. The designers do not need to worry his complex shape or strange size can’t be allowed for produce via sand casting, and mainly rely on their imagination of the products.
4.     4.Small quantity are permit in the production.
5.     For this kind of Aluminium casting process in our foundry, there are always 8 steps to perform the whole Aluminium sand casting process:
6.     1.Place a ready pattern (normally made from wooden, Aluminium or steel) in sand to create a sand mold.
7.     2.Incorporate the pattern and sand in a gating system.
8.     3.Remove the pattern.
9.     4.Fill the mold cavity with molten Aluminium alloy.
10.     5.Allow the Aluminium alloy to cool.
11.     6.Break away the sand mold and remove the casting.
12.     7.Removing the burs or flashes of the castings
13.     8.Sent castings for next treatment if there were, such as heat treatment T5, T6, or machining, or coating operation like mirror polishing, painting, powder coating, e-coating and such on.
