Mold plate = cavities × pitch + 2 × border.

Material price (per m²)/m²

Ranks part orientations by material cost per cavity. Higher scrap price favors higher utilization.

Material price (per m²)/m²

Packs the demand with a rotation search; ranks by cost per part (lower is better). Cost per cavity is identical for all part types on one sheet.
