With advancements in the display industry, LED display cabinets are no longer made solely from iron; they can also be manufactured using aluminum and die-cast aluminum materials. What are the differences between LED display cabinets made from iron, aluminum, and die-cast aluminum? Let’s take a closer look!
Manufacturing Process
In terms of manufacturing process, LED iron cabinets primarily use CNC machining methods and welding techniques to ensure dimensional accuracy and achieve precise component alignment. LED aluminum cabinets primarily employ sheet metal fabrication processes to form specific shapes and dimensions. LED die-cast aluminum cabinets primarily utilize die-casting processes, which involve injecting molten aluminum into prepared molds under high pressure, followed by cooling and shaping for mass production.
Weight
Weight is a key indicator for distinguishing the material of LED display cabinets. According to measurement results using the control variable method, the weight of LED iron cabinets is 45 kg/㎡, LED aluminum cabinets weigh 35 kg/㎡, and LED die-cast aluminum cabinets weigh 30 kg/㎡.
It can be seen that LED iron cabinets are the heaviest and require multiple people to move them. LED aluminum cabinets are the lightest, making them easier for staff to install and dismantle, thereby improving efficiency. The weight of LED die-cast aluminum cabinets falls between the two, but they are relatively lighter compared to LED iron cabinets.
Durability
Rust Resistance
The rust resistance of LED iron cabinets is relatively poor. Although modern LED iron cabinets are coated with a protective layer or film to isolate water molecules from the iron surface, these protective layers wear off at a certain point, allowing the iron elements in the cabinet to react chemically with water molecules in the air, forming iron oxide, commonly known as rust.
While LED aluminum cabinets react with water more slowly than LED iron cabinets, they still react faster than LED die-cast aluminum cabinets. Therefore, LED aluminum cabinets have better rust resistance than LED iron cabinets but slightly inferior to LED die-cast aluminum cabinets.
Heat Dissipation
In terms of heat dissipation, LED die-cast aluminum cabinets have the best heat dissipation performance, followed by LED aluminum cabinets, while LED iron cabinets have relatively poor heat dissipation performance.
The reason is that LED die-cast aluminum cabinets have a high thermal conductivity coefficient, and their die-casting process increases the surface area for heat conduction, accelerating heat dissipation. LED aluminum cabinets have the same high thermal conductivity as LED die-cast aluminum cabinets, but they lack the large surface area to enhance heat dissipation. LED iron cabinets have lower thermal conductivity and surface area compared to the former two.
Aesthetic Design
LED display cabinets made from different materials feature distinct aesthetic designs. LED die-cast aluminum cabinets offer the most modern and stylish appearance, capable of being customized to contemporary design trends; LED aluminum cabinets have a more minimalist and elegant appearance; LED iron cabinets feature a matte black finish. In terms of aesthetics, die-cast aluminum LED cabinets are more likely to be preferred by users.
Maintenance Methods
In terms of maintenance, LED iron cabinets and LED aluminum cabinets primarily use rear maintenance, allowing users to open the LED display cabinet from the back. LED die-cast aluminum cabinets primarily use front-and-rear maintenance, enabling access from both the front and rear, thereby improving installation and maintenance efficiency.
Price
The LED iron cabinet offers the best cost-effectiveness among the three; the LED aluminum cabinet is more expensive than the LED iron cabinet; and the LED die-cast aluminum cabinet is the most expensive of the three.
