SAND Casting Services

Sand casting is widely used because of its ability to cast metals that have high melting temperatures, low cost, and flexible production options. Unlike other casting options, sand casting is an affordable way to cast larger parts without expensive machining costs. 

Both sand casting and investing casting have been around for ages. Investment casting is typically used when an engineer or designer needs smaller parts with intricate details. Sand casting allows for the production or larger, heavier parts and at a lower cost. Investment casting tends to be more labor-intensive since mold creation requires more steps prior to casting and additional machining steps after the metal has cooled. 

Out of the most widely used metal casting methods, sand casting is the least expensive for smaller batch runs. It is also a cost-effective model for large part production

The three types of sand used for sand casting are Green Sand, Silica Sand, and Resin sand. Sand casting with green sand is fast and inexpensive because sand is able to be reused for later castings. Its soft, reusable properties also mean the mold can shift or collapse during the casting process. Silica sand is a good choice because it can quickly turn from liquid to solid. Casting with silica requires more time because of additional steps to break down the mold after the metal has cooled. Resin sand allows for a smooth surface mold, which translates to fewer defective parts. This sand also comes with slower casting time and higher cost.
