Initially, aluminum vessels were used to store water. But as years passed, those vessels were transformed into bottles for enhanced functionality. Aluminum bottles have to undergo a lot of pressure and several testing methods to be useful. Since aluminum is highly likely to deplete in water, it needs proper insulation too. Therefore, specific care is required when packaged water is served in these bottles. The step-by-step guide below will help you understand the entire procedure.
Gathering Raw Material
The raw or primary material of these bottles is, of course, aluminum. Manufacturers ensure that the aluminum they use is recyclable, rust-free, and corrosion-resistant.
Going Through Extreme Pressure
Any metal has to go through extreme pressure to form a shape. To create a bottle, a cylindrical shape is employed in which the aluminum is compressed to form a desired bottle.
Necking Procedure
One cannot drink water from molded aluminum. There are chances of getting hurt by its edge. It is where the necking process comes into the picture. The metal is wrapped at the mouth of the aluminum bottle, leaving a center space ideal for water flow. It is made considering the size of the cap.
Cleaning The Bottles
Once this process is completed, manufacturers move to the following procedure, i.e., cleaning or washing. All bits and particles of metal, dirt, dust, and grime are cleared in this process.
Insulating Using Polymer
As said earlier, aluminum items must go through insulation, so the metal is not depleted in the stored liquid. It is carried using high-tech polymer plastic. Insulation is done in the interior of the bottle after which the bottle is heated for 10 minutes at a high temperature.
Spraying Process
Now that the bottle is ready, it is given a metallic appearance using a spray. In addition, it is also given an acid bath so that the bottle layer thickens and stays free from rust and corrosion.
Adding Details
Plain bottles don’t really attract customers. Hence, colors and designs are added to the aluminum bottles to increase their aesthetic appeal. Screen printing, embossing, or pad printing are some methods used in this process. In addition, some brands may customize the designs on the bottle as per the client’s demand. For instance, names and logos are generally printed.
Heating It Again
Solidifying the detailing is necessary before the bottle is packed to sell. Hence, reheating ensures that everything is intact and the exterior is smooth enough to appear pleasant on holding.
