10 Exceptional Benefits of Aluminum Enclosures

 

 

Very Light Weight
Aluminum has a high strength-to-weight ratio. Aluminum enclosures are lightweight, yet strong.

 

Extremely Strong
The strength of aluminum offers much better fracture toughness than most other materials used in enclosures construction. It is resistant to impacts, mechanical breakage, and propagation of fractures; it does not easily stress, tear, or crack.

 

Extraordinary Resistance to Corrosion
Aluminum is highly resistant to nearly all substances – such as salt water – that cause corrosion and weathering. Exposure to UV rays for long periods has no effect.

 

Insensitive to Temperature Extremes
The characteristics of aluminum remain constant over a wide temperature range – 80 °C to + 150 °C. In cold weather, aluminum enclosures do not become more fragile and brittle; instead, the tensile strength increases without lose of ductility. The low coefficient of thermal expansion of aluminum allows it to sustain higher temperatures without distortion.

 

Naturally Protects Electronics

How Do Aluminum Enclosures Differentiate Between Die-Cast Aluminum And Extruded Aluminum?
 

The aluminum enclosure is stamped with aluminum alloy material, which has the characteristics of good ductility, low density, electrical conductivity, heat transfer, corrosion resistance, beautiful appearance, etc. It is widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial Control, machinery and other industries. So how do aluminum project box distinguish between die-cast aluminum and extruded aluminum?


How to distinguish between die-cast aluminum and extruded aluminum?


The principle of extrusion is to apply pressure to the aluminum rod in the extrusion cylinder, so that the aluminum rod close to the melting point is extruded into the shape of the die hole through the die hole of the die. Therefore, the extruded aluminum profile is equivalent to the extension of a two-dimensional plane. In theory, this plane can be extended infinitely. However, due to the limitation of the length of the equipment, the later operation of the long material is difficult, and the extruded aluminum profile is generally not more than 6 meters long. Then cut according to the actual size used.

 

The principle of die casting is to completely melt the aluminum alloy and then inject it into the three-dimensional aluminum enclosure mold, and maintain a certain pressure. After cooling, the mold is opened, and a die-cast aluminum alloy enclosure is completed. Die-cast extruded aluminium enclosure has a wider variety of appearances.

 

It can be seen from the above that the extruded aluminum project box can only change its shape in a two-dimensional cross-section, while the die-cast aluminum enclosure can change its shape in any part in three dimensions. Die-cast aluminum can be made into a hollow ball, while extruded aluminum can only be made into a hollow round tube, and its two ends are open. Therefore, both ends of the extruded aluminum casing will be sealed with a cover or an aluminum plate. The die-cast aluminum housing can be made into a box shape and covered with a cover plate. But our extruded aluminum profile enclosures are still more common than die-cast aluminum enclosures. Why?

 

Because the die-casting aluminum mold is expensive, and the production efficiency is not as good as the extrusion aluminum profile, the processing cost is also relatively high. Die-cast aluminum housings are required in some cases where a waterproof seal is required.

How to Build Aluminum Enclosures for Electronic Projects
 
Step 1: Design Specification

Getting the right specifications is essential to determine whether you need extra protection or shielding from dust, chemicals, and moisture. Even the slightest errors in dimensions could cost more than your budget can manage. Design the aluminum battery box precisely, considering features, dimensions, ratings, power supply, and where it will be used.

 
Step 2: Designing the Aluminum Enclosures

In the design phase, consider the panel, enclosure layouts, and thermal aspects to customize the electronic enclosure to meet your requirements. Check the cut-out dimensions or use template cut-outs to ensure the customized electrical enclosure works to your specifications.

 
Step 3: Fabricating and Machining the Aluminum

After designing the enclosure, it is time to cut the material to size using accurate measurements. There are various methods to cut metallic materials, including punching, shearing, blanking, laser cutting, and water jet cutting.
After cutting the material into the desired shapes and dimensions, bend the panels to conform to the enclosure designs.

 
Step 4: Assemble the Aluminum Electronic Enclosure

There are several joining methods for building custom electronic enclosures. Welding is a preferable option if you are considering a permanent project box. In addition, you can join the materials using mechanical methods such as riveting, bolting, clinching, folding, or screw joining. The joining method you choose may affect accessibility, so you must consider maintenance and replacement requirements first.

 
Step 5: Surface Finishing

You can finish the aluminum surface in various ways to give it a more desirable look. Since you are using aluminum, consider wet painting or powder coating to achieve a waterproof aluminum box. Aluminum can also be anodized by immersing it in an acid bath to improve aesthetics and surface protection.

 
Step 6: Fix the Electronics

After finishing the exterior of the enclosure, mount the electronics inside, considering the connection cuts you made earlier. Lay out the electronics using desirable spacing and configuration, leaving room for connectors and wires. Some manufacturers build PCB standoffs with sticker backing; sometimes, you will need to drill the standoffs to fit perfectly. Once you are done, mount all the electronics, switches, buttons, and connectors, and start wiring.
