Our professional soap cutting machines have two cutting grids. The first step is the loaf cut, which splits your large block of soap into loaves. The second step is your bar cut. The loaf cut takes the place of having to use dozens of individual loaf molds. After you cut your loaves, stack them together to cut all of them at once with your bar cut. Air Cutter Mold Example: Making a 3″ x 2″ x 1″ bar in an Air Cutter mold will get you 42 loaves per mold (first cut) and 13 bars per loaf (second cut), which gives you 546 bars per mold. In this situation, the loaf cut replaces 42 single loaf molds with one block mold. The bar cut with multiple loaves stacked together replaces 42 individual bar cuts with a small loaf cutter, giving you 546 bars with a single cut (13 bars per mold x 42 loaves).
