An automatic flatbed creasing and die-cutting machine for duplex paper is the right choice when you need clean, accurate cuts and creases on folding-carton board — and light corrugated — at medium-to-high volume. Unlike a rotary die-cutter, a flatbed press applies even pressure across the whole sheet, which suits the crisp creases and fine detail that duplex cartons demand. BMC's NDAD range runs at up to 7,500 sheets/hour and 300 tons of cutting pressure across sheet widths from about 1,080 mm to 1,650 mm.
What "for duplex paper" actually means
Duplex board (grey-back or white-back folding-carton board) is thinner and stiffer than corrugated, and it shows creasing quality far more visibly on the finished box. A machine tuned for duplex paper combines accurate registration with even platen pressure so creases fold cleanly without cracking the coated surface. The BMC NDAD models handle cardboard from roughly 250 gsm upward, and the smaller models also cut light corrugated up to about 10 mm — so one press can cover folding cartons and light shippers.

How to size the machine to your work
Notice how the rated speed falls as sheet size rises: the 1080 model is rated at 7,500 sheets/hour while the 1650 model runs at 5,000. Larger sheets mean a bigger, heavier press moving more mass per stroke. So don't buy the widest machine "to be safe" — size it to your largest real blank plus a sensible margin, and you keep the higher throughput. Confirm your smallest blank sits above the minimum sheet size too.
Buyer checklist
- Largest and smallest blank — both must fit the max sheet and min sheet sizes.
- Board types — confirm duplex weight and whether you also need light corrugated (up to ~10 mm on the smaller models).
- Throughput — plan around the working speed for your sheet size, not the design speed.
- Pressure — 300 tons across the range gives margin for tougher dies and heavier board.
- Support — installation, operator training and spare-part access.
Keep cuts in register
Even the right press needs correct set-up. If you see drift or ragged cuts, work through our die-cut misalignment troubleshooting guide. You can also compare other configurations in the full die cutting and creasing machine range.
Summary
A flatbed creasing and die-cutting machine for duplex paper delivers the crisp creases and detail folding cartons need, with even full-sheet pressure. Size it by your real blank dimensions and plan capacity around working speed. Tell our engineers your sheet sizes, board grades and volumes and we'll recommend the right NDAD model.
