In terms of structure, The VIP cold chain box can be divided into three types: VIP board splicing into a box, PU-VIP foam splicing together into a box, and PU-VIP overall box foam into a box.

VIP vacuum insulation plate core material is mainly divided into powder core material and glass fiber core material two. Silica as the material of the powder core material vacuum insulation board, thermal conductivity is relatively high, mainly used in wall insulation. The thermal conductivity of vacuum insulation board with glass fiber core material is lower. The thermal conductivity of VIP insulation board is 0.00025W/m.K, which is mainly used for energy saving and heat preservation of refrigerators, freezers and refrigerated vehicles.

Process

1. Prepare materials outside the mold (aluminum sheet - cutting and planting, gluing and folding).

2. Fixation of materials inside the mold (sticking leakproof strip, inner liner adhesive, inner liner assembly, VIP board adhesive, fixing VIP board, outer panel assembly, adding protective Angle).

3. Foam (add PU foam material) for 15 minutes.

4. Finalize the design.

5. Trim, tear film, wrap Angle wrap edge, add glue, add protective plate, wrap Angle wrap surface, wrap, seal.
