Sand Casting is the most common metal casting process. In this process molds are made of sand and mixed with a bonding agent such as clay, then compacted around the three-dimensional pattern.
This approach is suited to all kinds of ferrous and nonferrous alloys, as light as 100 grams (0.2 lbs) with little or no weight limitations.
US Castings offers various sand casting processes:
