Define what round-corner hard-case design must achieve.
A round corner rigid box making decision starts with the real product, complete format range, material specification, accepted-output target and the operation that receives the result.
Technical control plan
Design the radius around board and covering-sheet behavior.
Round corners redistribute material around a curved edge. Radius, board caliper, grain and allowance determine pleats, wrinkles and edge coverage.
01Set the radiusDimension the finished corner and the board profile used to create it.
02Select the covering stockRecord thickness, coating, grain, stretch and marking sensitivity.
03Develop the allowanceProvide enough material for coverage without excessive bunching.
04Trial the forming sequenceRun production components through registration, folding and pressing.
05Approve visual limitsDefine acceptable pleats, symmetry, exposed edge and surface marking.
Variables that change the equipment decision
- Corner radius and board caliper
- Paper grain, stretch and coating
- Artwork position near the curve
- Allowed pleat, wrinkle and edge exposure

Scope boundary: The same radius can behave differently with another paper, board or grain direction; keep an approved sample for each material family.

Frequently asked questions
Questions about round-corner hard-case design.
Use the answers as a starting checklist and confirm project-specific statements with current technical evidence.
Why does round-corner hard-case design matter?
It can change feeding stability, registration, wrapping quality, repeatability or the acceptance result for the finished component.
Can a catalogue value replace a sample trial?
No. Catalogue values screen the project; actual materials and an agreed inspection method determine practical fit.
Which variables should be recorded?
Record material specification, flat dimensions, machine settings, ambient conditions, defects, accepted output and the approved reference sample.
How should a process change be evaluated?
Change one controlled variable at a time and compare the result against the same approved sample and inspection criteria.
