How to specify carton size range for a case erector (and avoid the 3 common mistakes)
· Engineering · Product Knowledge
Most erector complaints trace back to a size range that looked fine on paper. Here is the checklist our engineers use before quoting.
Mistake one: quoting on the flat blank size instead of the erected carton. The machine's limit is the erected dimension plus the flap overhang — a 500 mm carton may need 620 mm of machine space.
Mistake two: ignoring board grade. A B-flute carton and a BC-double-wall carton of the same dimension behave completely differently in a vacuum pick-up. Always send us three samples, not a drawing.
Mistake three: sizing for today's range, not next year's. If your SKU count is growing, allow 15% headroom on the length range — it costs little at the factory and cannot be added later.
Our quoting form asks for: erected L×W×H, board grade, cases per minute, carton stack height in the magazine, and a photo of a real carton. With those five items we can commit to a performance figure.
