Control form: Lamination and curing protocol
Document material choice, mixing ratio and curing for each laminate you cast
Complete the form continuously while you work—not afterward from memory. Precise documentation makes it possible to find the cause if a laminate later proves to be too weak or does not cure correctly.
| Field | Noted as |
|---|---|
| Date and order/item number | Date + unique ID |
| Resin type and batch number | E.g. polyester, batch xxxx |
| Resin to hardener ratio | E.g. 100:2 according to supplier's instructions |
| Ambient temperature during casting | Degrees Celsius |
| Number of layers and fiber type per layer | E.g. 4 layers fiberglass mat 450 g/m² |
| Start time and expected cure time | Time of day + timer |
| Visual inspection after hardening | No air bubbles / dry spots / deviations noted |
| Performed by (initials) | Your signature/initial |
§Why it is important
Mixing ratio and ambient temperature have a direct impact on how well a resin hardens. Too cold, and curing can be incomplete or take much longer than expected. Incorrect mixing ratio can result in a laminate that never reaches its full strength, even though it appears cured at first glance.
Storage of the form
Save the completed form with the rest of the production documentation for the order, so it can be found again if there is later a question about the quality of the item in question.
