Raw material and selection

The common choices are 1000, 3000 and 8000 series. Conduct quality checks on raw materials to ensure their surfaces are smooth and free of impurities.

Smelting

Add the selected aluminum alloy into the furnace for smelting. Process parameters such as temperature, pressure and time need to be controlled during the smelting process to ensure the quality and stability of the aluminum alloy. After the smelting is completed, the molten aluminum alloy is poured into the prepared casting mold for preliminary shaping.

Casting and rolling

Put the initially formed aluminum block into a casting and rolling machine and roll it to the required thickness and width. During the casting and rolling process, parameters such as rolling temperature, speed and pressure need to be controlled to ensure the thickness, flatness and surface quality of the aluminum foil.

Heat treatment

Heat treatment is performed on the cast-rolled aluminum foil to eliminate its internal stress and improve its hardness and corrosion resistance. During the heat treatment process, process parameters such as heating temperature, holding time and cooling method need to be controlled to ensure the performance and stability of the aluminum foil.

Surface treatment

The heat-treated aluminum foil is surface treated to enhance its corrosion resistance and aesthetics. Surface treatment methods include painting, electroplating, anodizing,etc.

Quality inspection and packaging

Conduct quality inspection on the treated aluminum foil, including inspection of thickness, hardness, surface quality, etc. Qualified aluminum foil is packaged to protect its quality and safety during transportation and storage. The packaging method is determined according to actual needs, and can be paper packaging, plastic packaging or metal packaging.

In the production process of household foil, you also need to pay attention to the following points:

The quality of raw materials has an important impact on the performance and quality of aluminum foil. Therefore, it is necessary to strictly control the quality of raw materials and conduct regular quality testing.

Oxidation and impurity contamination need to be prevented during the smelting process. The quality and stability of aluminum alloys can be improved by taking appropriate protective measures and using pure raw materials.

During the casting and rolling process, parameters such as temperature and pressure need to be controlled to avoid problems such as cracks, bubbles and surface unevenness. At the same time, the casting and rolling mill must be maintained regularly to ensure its normal operation and effectiveness.

During the heat treatment process, process parameters such as heating speed, holding time and cooling method need to be controlled to avoid problems such as deformation and cracking. At the same time, appropriate heat treatment processes should be selected according to different varieties and specifications of aluminum foil.

During the surface treatment process, it is necessary to select a suitable treatment method and control process parameters such as treatment time and temperature to ensure the surface quality and aesthetics of the aluminum foil. At the same time, surface treatment equipment must be maintained regularly to ensure its normal operation and effectiveness.

During the quality inspection and packaging process, quality standards and packaging requirements must be strictly controlled to ensure the quality and safety of household foil. At the same time, it is necessary to establish a complete quality management system and packaging specifications.
