What Is Sand Casting and Why Is It Used?

Pouring liquid metal into castings

Sand casting is a method used for casting metal by pouring molten metal into a mold made from condensed sand. It has been used for hundreds of years and remains to be one of the most reliable and versatile methods of creating different castings to this day. While the main process has not changed over time, there are new advances to the method that have been developed throughout the years.

Reasons to Use Sand Castings

Flexible Mold

The mold boxes made up of sand casting are extremely reliable and easy to make.  The sand mold can hold the metal’s shape as the metal cools down to reveal the desired cast design. The use of sand casting allows you to create highly complex shapes in almost any size and form from nearly every type of engineering alloy.   

Cost-Effective and Relatively Cheap

One reason why most metal castings around the world are manufactured using sand casting is that it is relatively cheap and cost-effective. Sand casting is one of the few available processes for metals that can be recycled because of its reusability. Its ability to mold sand to be reused is a great asset in manufacturing operations.  

Strong and Resilient

Sand casting molds provide the best outcome possible because it can withstand the high temperatures of liquid metal it holds when creating designs. It can also manage thermal contraction, metal flow, and gas venting to prevent defects and impurities during the process. By using high-quality sand in creating the mold, your project will not melt, burn, or crack as molten metal is poured into it.
