6 different types of collapsible Aluminium tubes surface treatment from manufacturer


There are many reasons to choose wholesale collapsible Aluminium tubes for Cosmetic Tube. Collapsible aluminium tubes are widely used, such as cosmetic aluminum squeeze tube packaging, toothpast aluminum squeeze tube, Aluminum collapsible tubing production for collapsible aluminium manufacturers cost is relatively low. It has high strength-weight ratio and corrosion resistance. It is environmentally friendly and can accept high performance coatings.

Collapsible Aluminium Tubes Manufacturers have decided to design custom Collapsible Aluminium tubes profiles, you need to make some important choices. One such choice is which finish option to choose from manufacturer.


Choosing a finish is important for two main reasons:

First, surface treatment aluminum packaging tubes can improve corrosion resistance.

Collapsible Aluminium tubes have a natural oxide film to prevent corrosion. This oxide film is sufficient for many applications. But in some Settings, additional protection may be needed.

Second, surface treatment can enhance the appearance of collapsible Aluminium tubes.

Depending on the aluminum packaging tubes you want to achieve, you'll need to choose the right finishes. Maybe you want something brightly colored. Maybe you want to achieve a "mirror" effect. You need to choose a finish that will give you the look you want.

Collapsible Aluminium tubes The following are 6 different types of collapsible aluminium tubes surface treatment:

Mechanical finishing

Collapsible Aluminium tubes can be polished, sandblasted, brushed, ground or sanded. These finishes can improve surface quality or prepare for other surface treatments.

Aluminum collapsible tubes preprocessing

Collapsible aluminium tubes can be etched or cleaned with alkaline or acidic materials. A pretreatment coating is then applied. The coating enhances the adhesion of powder or paint and provides resistance to corrosion.

Aluminium Tube bright dipping

The extruded parts can be bright impregnated to collapsible aluminium tubes with a mirror effect. To do this, technicians place profiles in special leaches-a mixture of hot phosphoric and nitric acid. After bright impregnation, the profiles can also be anodized to thicken the corrosion resistant oxide layer of the metal.

Aluminum collapsible tubes anodized

In addition to the natural oxide film, this electrochemical process provides additional protection. A durable porous anodic oxide layer is formed on the collapsible Aluminium tubes surface. Anodized Collapsible Aluminium tubes can also accept bright colors. Anodized Collapsible Aluminium tubes or their alloys improve surface hardness and wear resistance.

Aluminum collapsible tube spray painted

Spray paint is the use of compressed air to disperse liquid paint (commonly known as paint) into paint mist particles adhere to the surface of the profile, these coatings have a variety of colors, liquid paint usually contains volatile organic compounds (VOCs). They are removed during curing or baking. When the volatile organic compounds disappear, a large number of solids form films on the profiles.

Aluminum collapsible tubes powder coating

Powder spraying is to use powder spraying equipment (electrostatic spray molding machine) to spray the powder coating to the surface of the workpiece, under the electrostatic action, the powder will be evenly adsorbed on the surface of the workpiece, forming a powdery coating; The powdery coating is baked at high temperature, levelled and cured, and becomes a coating with different effects (different kinds of effects of powder coating). At the same time, powder spraying does not contain volatile organic compounds.

Collapsible metal tubes heat transfer

Have you seen collapsible Aluminium tubes that look like wood? Profiles can be heat transferred after being coated with a powder base coating. Technicians wrap the profiles in a patterned film. The heat transfer process transfers the pattern directly to the extruded profile.

Aluminum packaging tubes summary

Whether you are designing a new cosmetic packaging decoration, collapsible Aluminium tubes are an important part of your project. Choosing the right finish will ensure that your extruded profile has the right appearance and proper corrosion resistance.
