and Not Good Registry Markers
Function
- The Registry Marker has a raised circle with the letters "N
" and "G " located within, raised to different levels (see
Fig.2).
- At the bottom of the die stroke, if a circle and a "G " are
stamped in your metal panel, the die is set properly (see
Fig.1).
- If a circle and "NG " appears, the hit is too hard (see
Fig.1).
- If no mark appears, the hit is too light (see Fig.1).

installation head and is positioned over the part panel that is to
