1  Core material selection
Aluminum grade：
      • Primary aluminum (such as 3003/5052 alloy) is preferred，Ensure that the mechanical properties meet national standards (such as JG/T334-2012), Avoid the lack of strength or color difference caused by recycled aluminum
Aluminum plate thickness adaptation：
·      • The thickness of the panel is recommended to be ≥0.8cm (such as fluorocarbon roll-coated board)，Bottom plate thickness 0.6~1.0mm，The overall deformation resistance is positively correlated with the thickness
According to usage:
Cabinet door/cabinet body: 18mm thick aluminum plate
Back panel/ceiling: 10mm
2 Honeycomb core structural parameters
Honeycomb core density and size
The honeycomb core side length is preferably 3×3mm or 5×5mm hexagonal structure，The higher the density, the stronger the support (need to be selected in combination with thickness)。
3×3mm core material: suitable for high flatness requirements (such as high-end cabinets
5×5mm core material: mostly used for 16mm thick panels, taking into account both lightness and strength
If you choose SPC honeycomb panel (plastic surface + aluminum core), it is only suitable for low-budget projects.
Sandwich process
• The aluminum honeycomb panel is recommended to use a composite structure of 0.8mm aluminum skin + 3×3 aluminum honeycomb core，Best stability；Three-layer honeycomb panel (0.65mm aluminum plate + offset honeycomb core) is suitable for high-end customization needs
3 Matching application scenarios
Building curtain wall/exterior wall
The wind pressure resistance should be ≥8000N/m². Fluorocarbon roll-coated plates with a total thickness of 25~50mm are recommended, combined with high-temperature curing adhesive composite process.
Interior decoration/custom furniture
Cabinet door/ceiling: choose 18mm thick honeycomb core + whole aluminum plate cutting process to avoid splicing deformation
Backboard/partition: 10mm thickness is sufficient, focusing on lightweight
Industrial/Aerospace
High-density aluminum honeycomb core (such as 5052AH14 alloy) is preferred and must pass salt spray test and wet heat test (paint film ≥ 25μm)
4 Process and quality verification
Surface treatment standards
Roller coating process requires paint film thickness ≥ 25μm, passes 48-hour salt spray and damp heat test, and guarantees no fading for 10~15 years
Fluorocarbon coating or color-resistant paint is preferred, and the acid rain and scratch resistance are better than PVDF
