This blog can give you an insight into the production process of aerosol aluminum cans.
The Raw Material - Aluminum
The production of aerosol aluminum cans begins with high-quality aluminum. Usually, aluminum ingots are the main starting material. These aluminum ingots need to meet certain purity and mechanical property requirements to ensure the strength and safety of the final can.

Production Process
Fried Slices
Extrusion: The aluminum is put through an extrusion process to form a long cylindrical aluminum tube.
Stamping and Drawing: The aluminum tube is then cut into appropriate lengths and stamped and drawn to form the basic shape of the can body, including the bottom and the side wall.
Trimming: After stamping, the edges and excess parts of the aerosol aluminum cans are trimmed to ensure accurate dimensions and a smooth appearance.
(Internal Treatment)
Cleaning: The inside of the aerosol aluminum cans is thoroughly cleaned to remove any impurities, oils, or dirt.
Coating: This coating is crucial as it prevents the contents of the aerosol from reacting with the aluminum and ensures the stability and safety of the product.
(External Processing)
Printing: The desired patterns, logos, and product information are printed on the outer surface of the can. Advanced printing techniques are used to ensure clear and durable printing.
Varnishing (Optional): Some cans may go through a varnishing process to enhance the gloss and protection of the printed surface.
(Assembly)
The can top is prepared, which often includes a valve mechanism for aerosol discharge. The top is then firmly attached to the can body through techniques such as crimping to form a sealed aerosol can.
(Quality Inspection)
Visual Inspection: Check for any defects in appearance, such as dents, scratches, or improper printing.
Leak Testing: Ensure there are no leaks in the aerosol aluminum can to prevent the aerosol from escaping or air from entering.
Pressure Testing: Test the can's ability to withstand the designed internal pressure.
