2008-Jun-20 - Gravity Die Casting Info

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.

Gravity casting is used for the permanent mold process with pleasing results. Gravity casting is usually used when the finished product is more visually based then structurally based which is why this method is a favorite of artists and even some jewelers. The loss of strength is due to the lack of pressure used in this process. For those that need the strength but still want to use gravity casting, more of the molten metal will need to be used which will increase the weight.

Relying on gravity will take patience, although it will be needed for larger products.

If you have never tried gravity casting then you should, because you just may be surprised by what such a simple thing like gravity can create. For the sake of humor, make an apple and see what happens.
