How to make aluminum honeycomb sandwich? There are two main ways:

Forming method: firstly, the aluminum foil strips are formed into corrugated strips, and then the corrugated strips are glued and laminated to form the aluminum honeycomb core blocks.

This method is only used for large or rigid alloy foils or non regular hexagonal sandwich panels.

Stretch method: first coated with glue on the aluminum foil, and then the aluminum foil stacked, glued into a stack, and finally stretched into the aluminum honeycomb core block.

Regular hexagonal or square bee lattices are manufactured using this method.

Process of making aluminum honeycomb sandwich panel by stretching method:

1, the first step for foil surface treatment. Degreasing before coating, usually using solvent steam degreasing, alkali washing and so on.

In order to improve the bonding strength and durability of aluminum foil, chemical oxidation, passivation and phosphorus treatment of aluminum foil can also be carried out.

2, second steps for aluminum foil coating. Glue glue and glue including vertical stripes.

The 3 and third steps are aluminum foil lamination and solidification. Fold the coated aluminum foil on the required number of sheets,

Then the reheat press or autoclave can be heated and pressurized.

4, the last is the stretching forming and processing of the sandwich. There are two solutions to this step: stretch first, then shape and shape first, then stretch.

The pre deformation method can be used for the small curvature of aluminum honeycomb panel structure. After processing the shape, the aluminum honeycomb panel core which is generally suitable for processing the profile or straight generatrix shape is drawn
