<p>the casting process can be very economical for part designs that require intricate contoured surfaces, thickness variations, and internal features.</p>

<p><big>Quantitative analysis</big></p>
<p>The castability of a design can be partially quantitatively determined by the following three equations. Better castability is denoted by a larger number.</p>
