Product Description0.012-0.1mm 3003 H13 Aluminum foil for honeycomb foil
3003 H18 Alloy Chemical Properties
Composition basis: Aluminum-manganese alloy (Mn about 1.0-1.5%).
Strengthening mechanism: Pure cold work hardening (non-heat
treatment strengthening).
3003 H18 Alloy Physical Properties
High strength: High strength level achieved through cold working.
High hardness: High surface hardness and relatively good wear
resistance.
Low ductility: Poor plasticity and limited formability. Not
suitable for drastic forming operations such as deep drawing.
Maintain good corrosion resistance: Excellent corrosion resistance
in atmospheric environment and many chemical environments.
Good weldability: But the heat affected zone of welding will soften
(strength decrease).
Good processability: Can be processed, but it takes more tools than
the soft state.
Production Process
Processing aluminum foil into honeycomb core is a precise and
highly automated process. The core is to form a continuous
hexagonal honeycomb cell structure through a special forming and
bonding process. The following are the main steps and process
details.
1. Aluminum foil preparation
Select aluminum foil coils of specific grade 3003 and thickness.
The aluminum foil surface needs to be degreased and chemically
treated (such as chroming or chromium-free treatment) to improve
the adhesion of subsequent adhesives.
2. Gluing
Apply high-strength adhesive in parallel stripes to specific
locations on the aluminum foil. The width and spacing of the glue
stripes determine the size and shape of the final honeycomb cells.
Gluing method: Precision roller coating or spraying to ensure that
the glue line is uniform, continuous and precisely positioned.
3. Corrugation forming
The glued aluminum foil will pass through a set of precision
corrugation rollers. These rollers press the originally flat
aluminum foil into a continuous wave shape.The peak distance and
height of the corrugation need to be strictly matched to the
spacing of the glue stripes.
4. Lamination and lamination
Precisely align and stack multiple layers (usually dozens to
hundreds of layers) of pressed corrugated aluminum foil. Key point:
The peaks of each layer of corrugated aluminum foil must be
precisely aligned with the position of the glue stripes of the
adjacent layer.
5. Lamination and curing under high temperature and pressure
The hot press or continuous hot press belt applies pressure and
heat to the laminate. The adhesive melts, flows and solidifies,
firmly bonding the contact points of adjacent corrugated aluminum
foils. After curing, bonding points are formed between adjacent
aluminum foil layers at the glue coating, and the uncoated
corrugated parts naturally open up to form the prototype of
honeycomb cells.
6. Formation of "honeycomb block"
After lamination and curing, the originally separated multi-layer
corrugated aluminum foil becomes an integral aluminum block with a
regular pore structure inside, called a "honeycomb stack" or
"honeycomb core blank". At this time, the honeycomb cells are
connected in the direction perpendicular to the plane of the
aluminum foil, but the cells along the plane of the aluminum foil
have not yet fully opened.
7. Stretching and unfolding
Fix the two ends of the cured honeycomb stack on the stretching
machine. Apply tension perpendicular to the corrugation direction.
Under the action of tension, the bonding points between the
corrugated aluminum foil layers serve as fixed points. The troughs
of the corrugations are pulled apart, and the originally stacked
cellular structures are evenly spread out like an accordion.
Finally, a three-dimensional honeycomb structure with regular,
continuous, hexagonal cellular cells is formed. The stretching
speed and strength must be precisely controlled to ensure that the
cellular cells are evenly opened, without tearing or deformation.
