Key Sourcing Criteria for Vacuum-Formed Light Box Buyers

1. In-house mold & vacuum forming workshop: The core advantage for custom 3D, curved and irregular light box shells, distinguishing true thermoforming factories from trading companies that only assemble flat acrylic panels.

2. Material capability: PMMA (acrylic), ABS, PC, PS sheets; buyers should confirm UV-stable, high light-transmission raw material for long backlit lifespan.

3. LED optical system: Even light diffusion, low hotspots, constant-current drivers, optional low-voltage or dimmable LED modules.

4. Certification support: CE, RoHS, UL (when targeting the US market) and related safety test reports.

5. Export service: Sample lead time, bulk production schedule, pallet/carton packaging, drop test and after-sales technical support.
