A full polishing range.
From cutting and one-step correction to final finishing.
Use a pane-level production traveller to keep treated faces, exclusions and release status clear throughout a shower-glass coating process.
Updated · NANOLAB Knowledge

A glass panel can be correctly coated and still be installed with the wrong face toward the shower. A production traveller connects the treatment record to the physical pane as it moves through washing, coating, inspection and packing.
Use the drawing’s established orientation and a clear face designation. Include a small sketch showing holes, cut-outs or another reliable feature. Confirm that the naming convention remains understandable when the pane is turned over.
| Field | Example entry |
|---|---|
| Pane ID | Job and component identifier |
| Face A / Face B | Treated, untreated or excluded by instruction |
| Product and batch | Traceable material identity |
| Release state | Waiting, inspection hold or released |
A blank box should not mean both untreated and forgotten. Use explicit states and require a reason for an intentional omission.
Choose an approved tagging or packaging method that does not contaminate the treated area. Preserve the link between the traveller and pane when racks are rearranged. If identity is lost, hold the pane for resolution rather than guessing from water behaviour.
Check the physical orientation, drawing and traveller together before packing. Transfer the required face information to the installation instructions. A photograph of the packed orientation can help where the geometry is difficult to describe.
The traveller is most effective when it contains a few decisive fields completed at the relevant station. An elaborate form filled in from memory at the end of the shift provides weaker traceability than a short record that follows the actual pane.
Discuss a shower-glass coating project. For application and care, use the current instructions for the exact product.
