The Process Of Making Aluminum Water Bottles

Although some bottles are made of stainless steel rather than aluminum, most are made of aluminum. Is it safe to drink from aluminum water bottles? Will they be able to keep up with the stainless steel bottles? This may lead you to wonder how aluminum water bottles are made.

In this article, we will explore how an aluminum water bottle is made and see if this method makes the bottles as durable and practical for storing liquids as possible. But for more in-depth information about aluminum bottled water, just visit https://www.myownwater.com/aluminum-water-bottles

An extruding machine press stretches small pieces of aluminum into a long cylindrical shape to make aluminum water bottles. Before being heated and solidified in an oven, the insides are fitted with an insulating material. Anodizing or spray painting the exterior with an aluminum coating and a chosen color are the finishing touches.

Using an aluminum water bottle instead of single-use plastic containers is a great idea. This advantage, however, is the result of a meticulous procedure. Let’s look at how an aluminum water bottle goes through a series of steps to ensure it can store drinks effectively.

The Process:

To form the shape and include insulation materials, an aluminum water bottle must go through impact fabrication. Protective coatings, exterior colors, and designs are also required. Let’s take a look at how to make aluminum water bottles step by step.

1. Collection of Aluminum Alloy

To begin with, an aluminum water bottle is made of a recyclable aluminum alloy similar to that found in beverage cans. This malleable material is also rust and corrosion-resistant.

2. Impact Extrusion Press for Cylinder Formation

Impact extrusion is a method of producing metallic containers with unusual shapes. A backward extrusion process thins an aluminum slug to a few millimeters in thickness before stretching it into a long cylindrical shape.

A cold slug wall aids in shape formation, while a punch mechanism compresses the aluminum alloy contained within the container. The press machine ensures a smooth and quick formation process by creating a stable sliding motion. The machinery passes over the cylinder several times until the opening of the bottle is reduced to half its original size.

3. The Necking Process

Necking is the process of wrapping a sleeve around the neck of a bottle. Most manufacturers use a custom-engineered double-turret bottle opener that can narrow or widen the mouth of an aluminum bottle. This can add 2 to 3 millimeters to the length of the neck.

Despite the pressure, the finely balanced pressing results in a threaded bottle neck closure. This procedure also adds an extra piece of metal to the top of the bottle, which aids in the tightening of the cap. It’s critical that the cap screws match the neck measurements of the bottle to ensure that nothing leaks out.

4. Getting the Bottles Clean

The aluminum bottles are washed by an automatic scrubbing station to remove metal debris and excess lubricant.

5. Polymer Lining Process

After washing and drying the bottles, the next step in making aluminum bottles is to incorporate high-tech polymer plastic using a spray nozzle. This procedure insulates the interior of the building. When the bottle is heated in an oven for 10 minutes at 365 degrees Fahrenheit, the powder polymer will solidify. This step is critical because the insides of the bottles require an internal coating to keep the raw aluminum from reacting with the contents.

6. Epoxy Spraying and Anodizing

Spraying the bottle with a sleek aluminum coating for a smooth yet rich metallic appearance follows after the polymer has solidified. Epoxy, on the other hand, is more prone to scratching and peeling.

Anodizing is an acid bath that thickens the aluminum oxide layer through an electrochemical method. This also acts as an abrasion, corrosion, and rust barrier for aluminum.

7. Color and Design Additions

The coating may also include full-color printing or adding personalized designs, depending on the manufacturer’s marketing efforts. These finishing touches provide an appealing aesthetic that appeals to a wide range of tastes. The following are the types of common color and design additions for aluminum water bottles:

  • Screen printing involves transferring a design onto a bottle using an emulsion.
  • A high-tech laser engraves a design onto the surface of the bottle.
  • Pad printing: This printing method transfers a 2D design using a large stamp covered in ink.

8. Reheating Process

After spraying the desired color, the bottles should be placed back in the oven to solidify and ensure a smooth exterior. All that remains is to pack and deliver the items once the bottles have cooled and dried.
