For stamped parts, material is often the largest share of unit cost. A well thought-out strip layout is therefore not a detail of die design but a direct cost factor across the entire production run.
Nesting and part orientation
Rotating or mirroring the part can noticeably improve material usage. Rolling direction, bend lines and burr side all need checking, the tightest nesting is worthless if the forming operation then cracks.
Webs and carrier structure
Carrier webs must transport the strip reliably through every station. Webs that are too narrow cause strip breakage and downtime; webs that are too wide waste material. Sizing depends on sheet thickness, strength, feed pitch and the number of stations.
When a layout review pays off
For running series, reviewing the strip layout pays off whenever volumes rise significantly, the material changes or a die is being reworked anyway. A few per cent of material can often be saved without touching the part geometry.
