Did you know that sand casting is the most common casting process used today? The sand casting process is versatile and can produce parts ranging in size from a few ounces, to several tons, all with varying levels of complexity. Sand casting is relatively inexpensive and the process is fairly simple. It is commonly used to make parts out of gray and ductile iron, aluminum and zinc, but because sand can tolerate extremely high temperatures, sand casting is also often used for metals with high melting points such as steel, nickel, and brass.
Changing the sand casting method can yield parts of varying levels of dimensional accuracy and surface finish, but it does have its limitations. The different levels of dimensional accuracy are detailed in ISO 8062, an internationally recognized standard that can be an invaluable guide to help determine whether or not sand casting is the most appropriate process for meeting the design requirements of your parts.
At Brukar, we can help you decide whether or not sand casting is the way to go to meet your needs. We leverage the expertise is our supply base to try to determine different ways to reduce your part costs while maintaining your current design integrity and it may be as simple as changing the type of sand mold, or it might involve switching to a completely different casting process, such as investment casting. conversely, it may be that changing from investment cast parts to sand cast parts is feasible, effectively resulting in lower costs. It’s worth asking the question. Let Brukar help you find the answers!
