What's the point of draft in sand casting

2017521 · 10. You need pattern draft to be able to remove the pattern from the sand before pouring. If you don't have any / sufficient draft then edges can be weakened or damaged / broken when you remove the pattern from the sand or plaster - whatever material it is. It is not to help remove the casting as the sand mould is destroyed.
