What causes incomplete casting in the molding process?

Show Answers

Using an investment with excessive porosityHaving a sprue diameter that is too narrowEmploying a sprue pin that is hollowUtilizing an oversized reservoir

Explanation

Incomplete casting commonly occurs when the sprue diameter is too narrow, restricting the flow of molten material into the mold. Other factors like porous investment, hollow sprue pins, or large reservoirs do not typically cause incomplete casting.
