It also shows high resistance to corrosive forces, preventing rust accumulation.
Aluminum has high formability and can be transformed into many shapes and designs, making it suitable for designing front panels of unique shapes or sizes. Aluminum front panels would be highly aesthetic and visually appealing for you to look at, which makes them a widely popular choice.
Types of Aluminum Front Panels
Many aluminum panels with different features and purposes are available in the market. We will discuss some of the most commonly available aluminum front panels. These include:
1. Anodized Aluminum Front Panels
Some aluminum front panels are manufactured by an electrochemical process called anodizing. The anodizing process involves creating an oxide layer on the surface of the aluminum panel. The extra oxide layer is a barrier to corrosion agents and prevents the aluminum front panels from exposure to external corrosive agents, which could cause damage.
You can paint the oxide layer using different dyes to obtain different looks for your aluminum front panels.
2. Brushed Aluminum Front Panels
This type of aluminum front panel has patterns created using a wire brush.
The wire brush is brushed across the surface of the aluminum front panels. These patterns can help you hide surface defects on the panel while enhancing its visual appeal.
3. Polished Aluminum Front Panels
These front panels are polished using highly abrasive materials. First, you must use sandpaper to remove scratches from the aluminum surface. A polishing compound is then applied to the surface and dried for a glossy finish. The polished surface is smooth and reflects light making it visually appealing.
However, the high reflectivity of the polished aluminum surface can cause issues like glare and should be used with care for your specific application.
4. Matte Aluminum Front Panels
These front panels have a non-reflective surface with a matte texture. The matte finish is created by coating the aluminum surface with a light-scattering material. These panels are suitable for applications requiring minimum light reflection, such as outdoor applications.
Matte aluminum front panels have a sleek look and are preferred for industrial equipment. These front panels are also advantageous because they can hide surface defects like scratches and the presence of fingerprints.
5. Powder-Coated Aluminum Front Panels
Here, a dry powder is applied to the aluminum surface to manufacture powder-coated front panels. After this, the aluminum surface is cured at a high temperature, generating a coated surface. These kinds of aluminum front panels are long-lasting and resistant to scratches. You also have the option to create different textures on the aluminum surface using the powder.
How Are Aluminum Front Panels Manufactured?
Aluminum front panels are manufactured using different processes based on the kind of properties you require for your project. These include:
1. CNC Machining
In this process, you take the help of computer-controlled machines to help you cut your aluminum panel in your desired shape and size from a large block of raw material. You can create precise shapes using this technique, as you only need to instruct the computer on what to do. This manufacturing technique can also create complex shapes for aluminum front panels.
2. Sheet Metal Forming
Using this technique, you can cut a flat sheet of aluminum and bend it into your desired shape for a front panel. This method is suitable for creating front panels that are simple and flat in nature.
You can also force molten aluminum through a specially designed die to create shapes having long profiles. You can cut the extruded aluminum into your desired shape for the front panels. This method is suitable for mass production and for creating panels that have customized, unique shapes.
Customization Methods for Aluminum Front Panels
If you require your aluminum front panels to meet specific design requirements, you can customize them using different methods. These include:
1. Cutting and Machining.
You can use CNC machines or other cutting tools to cut your aluminum panels into unique shapes and required sizes. A CNC machine is preferable if you require high precision for your front panel design.
2. Laser Engraving
In the laser engraving process, you use a laser to remove material from the surface of your aluminum panel to engrave a design or text on the panel. These designs are permanent and have high precision.
3. Anodizing and Coloring
You can use an anodizing process to create an oxide layer on the surface of your aluminum front panel. Once this oxide layer is created, you can custom-color it to meet your specifications.
4. Screen or Digital Printing
Printing allows you to create different graphics or text on the surface of your panels. You can print your company’s logo on the panel or print other design specifications to customize your panels per your requirements.
