Tolerance is not only the number written on a drawing. Material stretch, cutting pressure, creasing position and machine setup decide how the part behaves in production.
Drawing scale is the first check
A PDF can look correct while scale is wrong. A control dimension and AI/DXF source file make the scale easier to verify when available.
- A control dimension is added.
- The cut line stays as a closed vector.
- The revision is named clearly.
Material can change the result
Board grain, corrugated flute, label liner or rigid PVC can affect final dimensions. Tolerance decisions must include material behavior.
- Gsm and thickness are written.
- Stretch or shrink risk is noted.
- Sample cutting is used when needed.
Creasing and cutting interact
If crease lines sit too close to cut lines, the part can deform. Creasing allowance and channel choice support dimensional stability.
- Check cut-to-crease distance.
- Folding direction is stated.
- Evaluate channel needs with material.
Sample checks protect production
For critical dimensions, series production should not start before the first cut piece is checked. The sample connects drawing intent with shop-floor reality.
- The first part is measured.
- Drift is tracked with file revisions.
- Old dies are rechecked on repeat jobs.
Quote details we clarify together
When the file, material, quantity and deadline are clear, the quote conversation moves faster and with less back-and-forth.
- Current revision file
- Material and quantity details
- Critical dimensions or production notes
- Deadline expectation and delivery preference
