Sand Casting Explained: A Proven, Cost‑Effective Metal Fabrication Method

Sand casting uses sand to create a mold for casting metal parts, from iron machine bases to cooking vessels. The process has been used for more than 3500 years and approximately 60 percent of all castings is still done using this method.

Advantages of sand casting

Sand casting offers a number of advantages. These include…

• Sand casting is generally less expensive than other casting methods of creating parts, especially when compared to investment casting.
• Sand casting can produce parts virtually in any shape and size.
• Works with most alloys. Sand casting can work with most ferrous and non-ferrous alloys.
• Short turnaround time. With sand casting, it’s quick to form the mold, which leads to overall short turnaround times.

Things to consider before deciding on sand casting

While sand casting has a number of important advantages, there are a few disadvantages you should consider before opting for this type of casting. These include…

• Rough texture. Surface finish of the sand casting is somewhat rough compared to parts made using other casting methods.
• Secondary machining required. Machining is generally required for sand casting to achieve features and accuracy required for fit-up and assembly.
