The appropriate draft angle can vary depending on several factors, including the type of metal being cast, the complexity of the part, and the design specifications. However, as a general guideline, draft angles typically range from 1° to 5°. For deeper features or more intricate designs, draft angles of up to 7° or more may be considered.

Another advantage is the excellent thermal properties of green sand. The sand can withstand high temperatures, typically exceeding 1500 degrees Celsius (2732 degrees Fahrenheit), allowing it to be used for casting a wide range of metals, including aluminum, iron, and steel. The sand also has good collapsibility, meaning it can easily break apart after the metal has cooled, simplifying the removal of the cast piece.

Advantages of using Grey Cast Iron in Sand Casting

After the molten metal cools and solidifies, the next step is to remove the mold. This is often accomplished by breaking the sand apart, revealing the cast object. The sand can typically be reused for future molds, making sand casting an efficient process in terms of material usage. However, the casting might require additional post-processing to achieve the desired surface finish and dimensional accuracy. This can include machining processes, grinding, or sandblasting.
