In traditional casting, molten metal is forced into the part or die with the help of a die head. The die head is made up of mandrels, which hold the metal together, as well as a cylinder containing mandrels and a hand-rolling machine. The hot metal is allowed to cool and solidify inside the mandrel. This is then raised above the working area by a criss-cross process called cranking.

The cranked process also results in a vacuum and suction that draw in other parts of the mold while the crankshaft simultaneously pushes the metal into the areas where it is needed.
In this casting process, however, only the mandrels are used and not the hand-rolling machine. (The metal castings are held together using the appropriate cement.) After the metal is raised above the work area, it is moved downward using a drum roller. This movement triggers a discharge of molten metal from the mandrel into the rollers below. After the metal is cooled, it can now be shaped according to the needs of the customer.
The second type of casting process is sand casting. In this casting process, a sand mold is filled with sand at its bottom. To shape the part, it is pushed inside the sand mold at a high-speed and then the metal is forced into it. This is a convenient method because the entire mold is completed at one time, which increases the ability to complete a large number of identical parts. However, because the sand mold has to remain open while the product is being shaped, this process requires more manual work than the first sand casting process.
Another type of sand casting parts is the slag pattern. This process uses thin strips of sand that are forced through a cone-shaped mandrel. Because the slag is ejected directly out of the mandrel, the metal often comes out in random patterns. This effect makes it difficult to achieve a smooth, consistent pattern on the finished product.
A third method of sand casting parts is the hot gas cooling process. Instead of using the mandrel to hold the metal in place, a blast of hot gas from a compressed air blast is used to cool the metal. Because of this, it is much less expensive than other types of casting, but it must be done quickly in order to keep the molten metal from spreading. It often causes problems during casting if the molten material does spread too quickly from the mandrel. These problems diminish once the heat source is removed from the equation.
Overall, sand casting parts are used by a wide variety of casting industries for a number of different applications. From traditional jewelry and figurines to automobile parts and precision components, this process continues to be widely used. It provides a great number of advantages over traditional methods. From cost savings to consistency, these are among the most compelling of reasons to use sand casting services.
