Honeycomb paper is cut, not moulded, so every shape is a die decision. A die that is right for corrugated will crush the cells, and a tolerance borrowed from folding cartons will leave gaps in a pack that was designed to be tight. The rules are short and mostly about where the blade meets the cell wall.
What die should be used for honeycomb?
A steel-rule die on a flatbed platen, with a 2 pt or 3 pt rule at 30 to 42 degrees of bevel depending on the paper weight, and a cutting pad of 1.5 to 2.5 mm depending on the caliper. Laser cutting works for prototypes and short runs but chars the edge and leaves a 0.2 to 0.4 mm brown line that shows on white paper; waterjet is clean and slow. For production above 5,000 pieces, steel rule at 15 to 60 USD per die is the cheapest correct answer.
How tight can the tolerance be?
Plus or minus 0.8 mm on a 200 mm dimension, and plus or minus 1.5 mm on anything above 400 mm, because the paper expands and contracts 0.3 to 0.6 per cent with humidity between 35 and 75 per cent RH. That is 1.2 mm on a 400 mm cushion, which is why a pack designed with a 1 mm clearance will jam in a humid warehouse and rattle in a dry one. Design to 2 mm clearance minimum, and 3 mm on any dimension above 300 mm.
Why do the edges crush?
Because a honeycomb has 85 to 92 per cent void and the blade meets an unsupported wall. Three fixes: a 25 to 35 degree bevel that slices rather than compresses, a urethane cutting pad rather than a hard board, and a nick pattern that leaves 2 to 3 mm bridges every 150 mm so the piece does not shift during the stroke. A crushed edge band of 3 to 5 mm is normal and should be allowed in the drawing, not fought.
How should folds and hinges be handled?
Score, do not crease. A 1.5 by 2.0 mm score with a 0.6 mm rule crushes the cells along a line and gives a hinge that folds within 2 degrees of square; a crease with a 1.0 mm rule delaminates the facing and the hinge fails at 20 to 40 cycles. For a 90 degree fold on 15 mm board, leave a 1.0 mm gap between the score lines so the material has somewhere to go.
What does tooling cost and how long does it take?
A steel-rule die for a 400 by 300 mm cushion runs 60 to 180 USD and takes 2 to 4 days; a rotary die for a web line runs 600 to 1,800 USD and 10 to 15 days. Counter dies add 40 to 60 per cent. A first article of 30 pieces is the minimum to prove the die, and it should be cut on the production press at production speed, because a slow stroke hides the crushing that a fast one causes.
What belongs on the drawing?
Trim dimensions with tolerance, grain direction, score positions with gap width, allowed crush band, bridge positions, and the packing orientation. Add the paper grade and caliper, because a 15 mm board and a 20 mm board cut with the same die give a 0.4 mm difference in the finished height that shows up as a loose fit.
How does die design affect pack-out and freight?
Two things. A die that nests pieces on the sheet at 5 mm spacing uses 6 to 9 per cent less board than one at 12 mm, which on a 400 by 300 mm cushion is 4 to 7 cents a unit at current board prices. And a die that cuts the piece 2 mm oversize to allow for crush gives a pack-out that shuts with hand pressure rather than a knee, which matters when the same carton holds 20 units at 12 kg. Draw the nest layout, not just the part.
Design the shape around the cell, allow the crush band, and the die will produce the same part in July and in January.
