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.

Raw material—aluminum ingot

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.

<The more detailed the requirements, the more accurate the quote>

Before the supplier gives the quotation to the customer, if the customer can provide more detailed requirements, the price obtained will be more accurate, the following is the product information that needs to be known before the quotation of aerosol cans (The content of this article will include aerosol tin cans and aerosol aluminum cans):

Product size

Aerosol tin cans and aluminum cans have several fixed diameters.

The diameters of tin cans are 45/49/52/57/65mm, 

Aluminum cans have diameters of 35/28/40/45/50/53/59/66mm.

Each diameter can be customized different heights, customers can refer to the forms below to determine what size to be customized.

Product Use

It is also very important to tell the supplier what the purpose of the cans is, as there are some products which the cans need to be customized with an internal coating (e.g. insecticide spray and air freshener). In addition, there are some regular sizes of products that will be available on the market, standard sizes that are customized by most manufacturers: 45x128mm and 52x130mm for Snow spray, 65x100mm for Air Freshener, 65x158mm for Spray Paint, 65x158mm for Butane gas can (straight wall can)
