Define what greyboard thickness and machine fit must achieve.
A greyboard thickness rigid box decision starts with the real product, complete format range, material specification, accepted-output target and the operation that receives the result.
Technical control plan
Specify board by measured thickness and behavior.
Nominal GSM and nominal thickness are not interchangeable. Machine fit and finished geometry depend on actual caliper, flatness, stiffness and cut quality.
01Sample each board gradeIdentify supplier, grade, GSM, nominal thickness and production lot.
02Measure actual caliperCheck multiple positions and record average and variation.
03Inspect flatness and edgesRecord warp, moisture condition, dust and cut accuracy.
04Trial the board layoutRun the thinnest, thickest and most frequent components.
05Define incoming limitsWrite the caliper and flatness range accepted for production.
Variables that change the equipment decision
- Actual caliper range
- Stiffness and moisture condition
- Board-piece width and joint geometry
- Cut accuracy, dust and edge quality

Scope boundary: GSM is a mass-per-area value; it cannot replace measured thickness when checking machine range, gaps or finished-case geometry.

Frequently asked questions
Questions about greyboard thickness and machine fit.
Use the answers as a starting checklist and confirm project-specific statements with current technical evidence.
Why does greyboard thickness and machine fit 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.
