How Aluminum Aerosol Cans Are Made？
Here are the general steps involved:
Aluminum aerosol cans are made through a process called extrusion and can form.
1. Extrusion: A cylindrical aluminum slug is created by pouring molten aluminum into a cylindrical-shaped mold. The slug is then heated to soften it.
2. Impact extrusion: The softened slug is then placed into an impact extrusion press, where a punch forces the slug through a die to form the can body. The punch is designed to form the neck and the shoulder of the can while compressing the slug to make the sidewalls.
3. Trimming and cleaning: The newly formed can body is trimmed to its final length and cleaned to remove any debris.
4. Coating and printing: The can body is coated with a layer of protective lacquer to prevent corrosion and is then printed with the desired design and labeling.
5. Can forming: The can body is then fed into a can-forming machine where the bottom and the valve cup are crimped onto the body, and the valve is inserted.
6. Pressure testing: The completed cans are pressure tested to ensure they are sealed properly and will not leak.
7. Packaging: The finished cans are packaged and shipped to be filled with the product to be sold.
This process produces a lightweight and durable container that can withstand the high pressure of the aerosol product inside.
Aluminum aerosol cans are a popular choice for packaging products such as personal care and household items, as well as food and beverage products. Aluminum is a lightweight, durable, and corrosion-resistant material that can be easily formed into a variety of shapes and sizes.
There are several benefits to using aluminum aerosol cans, including:
1. Protection: Aluminum aerosol cans provide an excellent barrier against light, oxygen, and moisture, which helps to preserve the quality and freshness of the product inside.
2. Sustainability: Aluminum is one of the most recyclable materials in the world, and recycling aluminum cans can save up to 95% of the energy required to produce new aluminum.
3. Convenience: Aerosol cans are easy to use, and the spray nozzle allows for precise application of the product.
However, there are also some concerns associated with the use of aluminum aerosol cans. One of the main concerns is the potential for the release of volatile organic compounds (VOCs) during the manufacturing process. VOCs can contribute to air pollution and have been linked to health problems such as respiratory issues and cancer.
Another concern is the potential for the cans to become contaminated during the recycling process, which can lead to the release of harmful chemicals into the environment.
Overall, the use of aluminum aerosol cans has many benefits, but it’s important to consider the potential environmental and health impacts and take steps to minimize them. This can include recycling aluminum cans, choosing products that use non-toxic or low-VOC formulations, and advocating for better environmental regulations and practices in the manufacturing and recycling industries.
EBI specializes in the production of aluminum aerosol cans since 2010, with mature and multiple automated production lines. The aluminum aerosol cans produced by EBI have reliable materials, uniform wall thickness, and can be printed in up to 9 colors.
Due to the European energy crisis, many European manufacturers have unstable delivery schedules. However, EBI only needs 30 days to produce 300,000 aerosol cans.
