Investment casting offers significant advantages over sand casting in many cases, though not all. If high-quality, precision cast parts are not needed, sand casting might be a good choice because of its low cost. It can also produce very large parts of more than 250 pounds. However, if high-quality parts that meet exacting standards and specifications are required, investment casting is by far a better choice. Specialized alloys, thin walls, complex geometries and better finishes are all additional pluses of investment casting. It is important to understand the comparative benefits and capabilities when choosing a production process.
