This kind of product mainly adopts the sand to cast the process, the external dimension of the products is required strictly, material: Aluminium alloy. Weight: 65 kg. Use: Apparatus outside cover.

'Gravity casting seems to be especially useful when dealing with aluminum and other light alloys. The basic idea behind this casting process is pretty much exactly what the name suggests. The metal is introduced into the mold by the force of gravity. Most other casting process either use natural pressure difference like the kind in certain sand casting procedures or they use forced pressure like in centrifugal casting to get the molten metal into the mold.

One of the most common uses for gravity casting is when permanent molds are going to be used. Also called a die, the permanent mold is really only economical for those planning on using the same mold numerous times and will need to keep the quality at a constant level. While some temporary molds can be repeatedly used the quality of the finished product will begin to suffer over time. With die molds the quality will remain the same. Die molds should be seen as an investment. Yes, they will be more costly then other molds; However they will outlast cheaper options for molds. With Permanent molds, they are created using cast iron, steel, and other metals. '
