2. Particle Size Smaller particles can generate finer cut quality and less surface roughness but may require higher velocities to achieve effective material removal. Conversely, larger particles can remove material faster but could introduce excessive surface damage.

1. Shell Coating Applying a thin layer of ceramic coating to the mold can improve surface finish and reduce defects. This technique acts as a barrier and provides a smoother surface for the molten metal.

The air set sand casting method is also relatively simple, requiring less sophisticated machinery than some other casting techniques. This simplicity can lead to lower setup times and easier maintenance. Furthermore, the process generates less waste than traditional methods, making it an environmentally friendly option in the casting market.
