Learning about aluminum tubes cosmetics packaging will be today’s agenda! Aluminum tubes are extremely common and one of the most popular packaging alternatives used in cosmetics marketing in the industry. We see them so often that we do not really think about how they are made. Well, this blog will clearly describe to you the whole process from start to finish. Heads up, they start off with just a circular aluminum disc!

Step 1: Aluminium Impact Extrusion Process 

Each tube is made from an aluminum slug about the size of a coin. The metal will spin around in the container which orientates them horizontally so they will fit through a channel below. The channel feeds the slug to a forming press. With a method called impact extrusion, each slug will compress to produce the exterior shape of the tube, including the neck. At the same time, a mantle will form the interior. This process hardens the metal, something they will correct later on while heating it. Tons of pressure will be applied and the tubes can be as narrow as 1cm and as long as 22cm.

Step 2: Trimming Process

The aluminum tubes cosmetics packaging process will continue with the trimming machine. It will cut threads into the neck of the tube, passing each one between 2 synchronized rollers. Stationary blades will trim the top of the neck, making the surface smooth and safe to handle.

Step 3: Faulty Pieces Check

Workers will check the initial body of the aluminum tubes to check for defects. Deficient tubes together with excess aluminum parts will be thrown away.

Step 4: Heating Process

The made aluminum tube structures will move along the convey belt to the heating machine/oven. The workers will help arrange the tubes in order. Heat is added to the tubes to make them more malleable and flexible for the next step.

Step 5: Transparent Glue Process

After heating to soften the metal, the tubes move through another machine. The rollers will apply a layer of glue on the body of the aluminum tube. A circular machine with about 10 grips allows each tube to be inserted into the grip and released once the glue is applied. This step is done to allow the convenience and ease of applying the colored print as the next step.

Step 6: Glue Heating Process 

Grippers place the tubes on long pins which move through the oven for around 7 minutes for the glue to dry.

Step 7: Color Print Process 

Off to the color print machine, each tube will make one complete rotation against the colored wheel. With pre-adjusted colors added to the machine, the wheel turns continuously to ensure an even coat onto the aluminum tube.

Step 8: Cooling Process 

The convey belt from the color print machine will bring the colored tubes to the last stage of the packing station. However, they have to undergo a cooling process first. Thus, the distance between the stations is far apart. This is to allow the colored aluminum tubes to dry completely before it reaches the final point.

Step 9: Packing Process 

The last and final step of aluminum tubes cosmetics packaging will be packing. Workers will inspect the aluminum tubes and package them accordingly into the carton boxes. Inspections such as chips in paint or material will make the packaging deficient. Hence, taken out of the batch of completed aluminum tubes.

Frequently Asked Questions

How many tons of pressure can be exerted with the extrusion machine?

It varies according to the complexity of the machine. It can go up to 3600 tons for large-dimension and complex products.

Can factories advise on the aluminum extrusion alloys?

Yes, factories have a team of experts to guide your preferred choice in terms of aluminum extrusions. Choices of alloys will be dependent on factors such as product function, design, and surface treatments, etc.

What are aluminum tubes used for other than packaging?

Aluminum tubes or tubings are used in aerospace, automobile, and rail transportation manufacturing industries. Moreover, due to it being heat-conductive, they render as a good alternative to heavier metals such as steel.
