Abstract

A method for testing casting quality includes collecting sand that has fallen from an internal cavity of the casting at a collection area. The collection area includes a screen and a pad. The method further includes capturing a first image of sand that has fallen onto the pad and analyzing the first image to determine an amount of black sand that has fallen onto the pad. The method further includes capturing a second image of sand that has been retained on the screen and analyzing the second image to determine an amount of black sand chunks retained on the screen.
