Several cabinet versions can share one graphic overlay drawing and one part number at the quotation stage. Approve the samples separately: give each actual bonding surface its own row, with the door revision, surface finish and trial application record. Leave any door without supporting evidence pending, even if it uses the same adhesive as a door already approved.
On November 12, 2026, Sungrow launched its PowerStack 3.0 commercial and industrial energy storage series and described a modular architecture that can be configured for different applications. The release does not specify the cabinet-door overlays or adhesives and does not disclose a Baoshengda supply relationship. On a separate energy storage project with multiple cabinet variants, buyers may want one order for the same overlay. The question is which door each trial application actually represents.
List the doors first, then decide which samples can cover more than one
Suppose two cabinet doors share the same outline, window and legends. One has a fine-textured powder coating; the other has a smooth painted finish. Quote against one drawing if appropriate, but distinguish the two bonding surfaces for sample approval. Ask the cabinet supplier for the controlled drawing or finish identifier, the actual bonding area and available samples. In the same quote, ask the overlay supplier to identify the adhesive and the surface used for the trial. If a supplier offers a flat coupon instead of a door, have both suppliers document the surface conditions it represents. A flat coupon cannot establish adhesion around a step, folded edge or window on the cabinet door.
The 3M 9472LE technical data sheet provides typical peel data for specific substrates and test conditions and says typical data should not be used as specifications. It illustrates why a report needs to identify the test substrate. It is not a recommendation to use this adhesive. Select the adhesive and application method and assess acceptance against the actual project sample and agreed criteria.
Share the drawing on the order, but make each approved door traceable
- Covered door: record the door revision, actual bonding surface, overlay drawing, adhesive part number and trial application record, and specify the batches eligible for release.
- Similar-looking door without a representative sample: quote the extra sample or trial separately. Mark the order line as pending; do not carry over a signature from another row.
- Later change to the finish or application process: check the affected row before deciding whether to repeat any testing. If a different adhesive is needed, distinguish it by part number or a controlled configuration so assembly does not pick the wrong variant.
The Baoshengda Technology graphic overlay and keypad overlay product page lists bonding substrate, surface treatment and use conditions as material selection inputs; see also the Chinese product reference. For a quotation, use the project contact page to share one overlay drawing and the list of door revisions. Identify the actual samples available for trial application and the rows that need separate pricing. An order for a graphic overlay or keypad overlay alone does not include switch circuitry. Adhesion approval for the overlay does not replace acceptance of the complete cabinet.
If the adhesive itself is changing, see how to define the approval scope for an adhesive substitution. If the door stays the same but field cleaning changes, see when to revisit an existing sample approval after a cleaning change. The cover shows a sample with a release liner. It does not identify an adhesive used in the project, the cabinet finish or any test result.
