When casting is complete, the plunger is drawn upward, pulling the metal back down the throat from the mouthpiece. The pot pulls backward away from the mold. The mold disk retracts from the vise studs which held it in perfect relation to the mold, thus breaking the slug away from the matrices. The mold disc then rotates counter-clockwise. In its travel, the slug base is trimmed by the back knife for height to paper (.918") and then returns to its neutral position in front of the "ejector blades" and aligned with the "knife block assembly" a pair of honed knives with a fixed knife, and a knife which is set to the point thickness of the mold liners being cast with. The knives are set to dead parallel. The fixed knife on the left bears against the smooth side of the slug (the mold body face of the slug) as it brushes next to it, and the right knife trims the ribs on the slug (the mold cap face of the slug). The disk stops when the mold is vertical, on the right, directly in front of the "ejector".
