Types of aluminum that can be used for metal collapsible tube bulk manufacture

Aluminum 1050: This is a commercially pure aluminum alloy with excellent formability and corrosion resistance. It is often used for applications where high ductility and weldability are required, making it suitable for collapsible tubes used in pharmaceutical and cosmetic packaging.

Pros: Excellent formability, making it easy to shape and manipulate into tubes.

Good corrosion resistance, suitable for packaging products with acidic or alkaline contents.

High thermal and electrical conductivity.

Cons: Relatively low strength compared to other aluminum alloys, limiting its use in applications requiring higher mechanical properties.

Aluminum 3003: This alloy is known for its moderate strength and excellent resistance to corrosion. It is commonly used for collapsible tubes used in packaging food products, beverages, and household goods like toothpaste.

Pros:

Moderate strength and excellent corrosion resistance.

Cons:

Lower formability compared to pure aluminum alloys like 1050 and 1070.

Aluminum 8011: This alloy is widely used for packaging applications due to its excellent formability, weldability, and corrosion resistance. It is often used for collapsible tubes used in pharmaceuticals, cosmetics, and industrial products.

Pros:

Excellent formability and weldability, making it ideal for collapsible tube manufacturing.

Good corrosion resistance and heat resistance.

Cons:

Slightly lower strength compared to some other aluminum alloys.

Aluminum 3104: This alloy offers good strength and formability, making it suitable for collapsible tubes used in various applications, including pet food packaging, household products, and automotive components.

Pros:

Good strength and formability, suitable for a wide range of applications.

Excellent resistance to corrosion, making it suitable for packaging food and beverages.

Cons:

Higher cost compared to some other aluminum alloys.

Aluminum squeeze tubes manufacturing process

The manufacturing process for aluminum squeeze tubes requires precision, expertise, and attention to detail to produce high-quality packaging solutions that meet the needs and expectations of various industries and consumers.

#1 Material Preparation: The process begins with the selection of high-quality aluminum sheets or coils, typically made from aluminum alloys such as 1050, 3003, or 8011. The aluminum material is inspected for defects and imperfections before being cut into precise dimensions to form blanks for the tubes.

#2 Tube Formation:

The blanks are fed into a customized metal tube-forming machine that shapes them into cylindrical tubes.

The forming machine utilizes a series of rollers and mandrels to gradually shape the aluminum blanks into seamless tubes of the desired diameter and length.

#3 Necking and Shoulder Formation:

For tubes that require necking or shoulder formation, a separate machine is used to shape the open end of the tube.

This process involves narrowing or flaring the opening of the tube to create the desired neck or shoulder profile, providing additional stability and functionality.

#4 Decoration and Printing:

Once the basic tube structure is formed, the aluminum squeeze tubes are passed through a printing machine for decoration and branding.

Various printing techniques such as offset printing, silk-screen printing, or digital printing may be used to apply branding, product information, graphics, or decorative elements onto the surface of the tubes.

#5 Internal Coating (Optional):

Some metal tubes may require an internal coating to protect the contents from interacting with the aluminum material, depended on the spefic product for packaging. This internal coating, typically made of epoxy resin or polymer coatings, is applied to the interior of the tubes using specialized spraying or lining equipment.

#6 Sealing and Closure:

The open end of the tube is sealed to create a closure mechanism, ensuring the integrity and freshness of the product contained within. Various sealing techniques such as crimping, folding, or welding may be used to securely seal the tube end. Once the tubes have passed quality control checks, they are packaged into boxes, cartons, or pallets for shipment to customers. The packaged aluminum collapsible tubes are then distributed to various industries and retailers for use in packaging a wide range of products.
