The manufacturing process of aluminum honeycomb core mainly includes the following methods:

1. Traditional manufacturing process

Preparation of Materials:

Select suitable aluminum alloys as the base materials, which need to be sheared, leveled, cut and other processes to ensure that their size and shape meet the requirements of subsequent processing.

Coating Treatment:

The substrate is cleaned, degreased, oxidized, etc., to remove the oil and impurities on the surface, and increase the roughness of its surface, so as to improve the adhesion between the coating and the substrate. Specialized binders and resins are used to firmly bond the alumina layer to the aluminium alloy substrate to form a composite material. The purpose of this step is to increase the surface coating adhesion and corrosion resistance of the aluminum honeycomb core.

Cellular Treatment:

The substrate coated with binder and resin is placed in a high-temperature furnace, and by controlling the temperature and time, the binder is thermally decomposed and the gas is released, resulting in the formation of tiny pores in the substrate. These pores will form the structure of the honeycomb core. By adjusting process parameters such as temperature and time, the size and density of the pores can be controlled, so as to obtain honeycomb core products with different requirements.

Molding Processing:

Through processes such as shearing, embossing, welding, etc., the honeycomb core is made into the desired shape and size. These process steps can be processed and assembled according to the specific requirements of the product.

2. Modern manufacturing process (forming method and drawing method)

Forming method:

First, the aluminum foil strip is made into a wavy strip, and then the corrugated strip is glued and stacked, and then processed into an aluminum honeycomb panel core after powder and fine sand. This method is suitable for alloy foils with relatively large thickness or stiffness, or unique aluminum honeycomb panel sandwich cores with non-regular hexagons.

Stretching method:

The aluminum foil is first smeared with a sealing strip, then the aluminum foil is stacked, riveted into a stack, and then stretched into an aluminum honeycomb panel core. Generally, regular hexagonal or square bee grids are made using this method.

Gluing: Including vertical bar gluing and horizontal bar gluing.

Lamination and dry solidification: The glued aluminum foil is stacked according to the required number of pages, and then heated and pressed in a panelizer or autoclave to dry.

Stretch forming: There are two main schemes for this step, namely stretching first and then machining the appearance and machining the appearance before stretching.

3. Other manufacturing processes

In addition to the above methods, the manufacturing process of aluminum honeycomb core also includes melting casting method, extrusion method, rolling method, foaming method and composite method, etc. These methods can be selected according to different market needs and product requirements.

4. Precautions

Throughout the manufacturing process, the process parameters and quality requirements of each link need to be strictly controlled to ensure the performance and quality of the final product.

The manufacturing process of aluminum honeycomb cores needs to be adjusted and optimized according to the specific production equipment and process conditions.

In general, the manufacturing process of aluminum honeycomb core is a complex and delicate process, which requires strict control of process parameters and quality requirements in each link. By adopting the appropriate manufacturing process and quality control measures, it is possible to produce aluminum honeycomb core products with excellent performance and reliable quality.
