16. Surface Finish. The average as-cast permanent mold surface finish is 200 to 420 RMS.This is smoother than sand casting (typically 300 to 560 RMS), but rougher than die casting (typically 20 to 120 RMS).. However, it's important to note that permanent mold castings typically have lower-porosity than sand or die castings. This means you can add machining …
Resin sand produces a denser, stronger, but less permeable mold. It is also a more expensive process than green sand casting. Green sand leaves a somewhat rough surface on the casting. This will typically be in the region of 200-500μinch Ra (5.0-12.5μmRa). CASTING DEFECTS The most common defects in sand casting are: • Porosity • Nonfills
