Diecast aluminum enclosures, also known as aluminum housing, have box-like structures. They are designed with the purpose of ensuring the protection of sensitive electronic devices and equipment in a wide range of working conditions such as industrial and commercial environments.

What is a diecast aluminum enclosure?

Diecast aluminum enclosures are technologically engineered to prevent damage to electrical equipment from dust and water with the help of their watertight seals. These housings are integral for safety of equipment in harsh climatic conditions. Their weatherproofing eliminates the possibility of damage from heat or water.

The diecast enclosures, due to their use of aluminum, are electrically conductive and are easy to ground. This quality plays an essential role in preventing electrical fires and eliminating shock hazard.

Their modern, industrial design also offers protection from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) preventing damage to electronic devices.

How are diecast aluminum enclosures prepared?

The die casting process is a metal casting technique that forces molten metal into a mold cavity under high pressure.

Diecast aluminum enclosures are prepared using the same method, in which the mold produces a box-like structure to meet specifications. Metals are hardened to produce the desired shape, using one of the two most popular techniques: cold-chamber or hot-chamber diecasting.

Since aluminum is a high-melting point alloy, the cold-chamber method is more suitable. This is because it uses a separate chamber to heat the metal and then transfer the molten metal to the casting machine.

The manufacturing process allows for high-volume production due to minimum finishing and machining requirements. Sunrise produces aluminum enclosures with machining, stamping and assembly. A variety of supporting features are also provided such as molded gaskets, powder-coated surfaces, fasting threads and recessed lids, along with shielding to prevent it from corrosion.

There can be some variations that can be introduced in both hot-chamber and cold-chamber such as:

Why are diecast aluminum boxes preferred over enclosures made from other alloys?

Diecast housing made from aluminum and its alloys have higher durability in comparison to enclosures manufactured from other materials. This is due to the resistance of aluminum to corrosive reactions unlike zinc’s corrosion in acidic and alkaline mediums.

Another factor contributing to the reliability of these diecast aluminum enclosures is the lack of reactivity of this metal. All of this offers maximum protection to the enclosure itself and its contents from external threats.

When compared to other metals and their alloys, aluminum’s light weight is another beneficial factor. Aluminum’s weight is only one third of that of steel while offering the same, if not more, strength.  It allows for efficient and more affordable transport of aluminum products over great distances via a range of transportation modes. It also makes the process of unloading and loading smoother to carry out as no extra measures are required.

Moreover, its weight increases the convenience of diecast aluminum enclosures application, in both personal usage and the industrial sector as aluminum is easier to manage than alternate metals and alloys.

The aluminum used in the diecast enclosures provides a natural barrier to these electromagnetic waves (EMI and RFI) and protects electrical equipment from malfunctioning or failing.


These qualities of aluminum enhance the protection diecast enclosures offer to all sorts of electrical appliances and devices that is unmatched by any other alloy

Are diecast aluminum enclosures and boxes aesthetically more pleasing than other such boxes? How?

The diecast aluminum enclosures, owing to their use of this durable alloy offer smooth, silver surfaces with an impressive finish. This innovative finish adds to their aesthetic appeal, making these housings suitable for many uses.

Such uses include LCD frames for which the housings are ideal, as they not only provide the required sturdiness and support, but also a modern looking exterior.

This aluminum exterior does not require high maintenance to maintain its natural silver shine. On the other hand, steel enclosures require regular upkeep in the form of paint for an impressive finish as they are susceptible to corrosion that can ruin outward the appearance of the housings as well as damage the interior.

Similar to steel, iron enclosures also react with moisture in the air overtime and form flaky, red-brown oxides on its surface, marring its appearance. Such issues are avoided with the use of diecast aluminum enclosures as they are resistant to deterioration over time as they are nonreactive. This ensures a first-rate exterior that is aesthetically pleasing and impressive to look at.

How cost-effective are diecast aluminum enclosures for industrial use?

Diecast aluminum enclosures are made affordable and highly cost-effective due to the combination of a variety of reasons.

Relative to other processes, these housings require minimal manual labor for assembly processes.

Moreover, the process of manufacture of diecast aluminum housings is more efficient and consumes less time when compared to the manufacturing times of other products. This well-structured process saves valuable time and allows for the costs to be more economical as it allows for increased levels of productivity.

As an alloy, aluminum is extremely durable and low maintenance, leading to low overall costs. Furthermore, aluminum is one of the most abundant metallic elements available. It eliminates possibilities of price surges due to shortages and allows manufacturers to maintain a reasonable and consistent price in the market.

For harsher settings, such as use in saline waters or water treatment plants, aluminum boxes prove to be higher versatile. They are coated for high resistance, making them immune to corrosion. Aluminum can achieve high level of ingress protection, much more than their plastic counterparts.

Are diecast aluminum boxes waterproof?

Diecast aluminum boxes survive well in outdoor conditions, even in a diverse range of climatic conditions including snow and rain. This is possible due to the waterproofing of these housings to prevent entry of water particles that could lead to damage to the contents of these enclosures.

Extensive waterproofing is ensured in these housings by the use of neoprene gaskets. Also known as polychloroprene, these gaskets are impermeable and thus restrict entry of particles of gases and liquids, including water.

In addition to water, the gaskets provide resistance on many fronts including but not limited to resistance to combustion, sunlight, ozone, chemicals etc. In combination with the durability of these neoprene gaskets, insulation of water particles is guaranteed in nearly all circumstances and conditions.

Furthermore, the water-resistant quality of the diecast aluminum enclosures is enhanced by the use of aluminum alloys. When exposed to water, a film of aluminum oxide forms that protects the underlying material from corrosion and vulnerability to leaks.

Do industrial electronics make use of diecast aluminum enclosures? Why?

In the industrial sector, there is immense use of electronic equipment and mechanical accessories both indoors and outdoors. A majority of these devices are vulnerable to malfunctions and failure if left unprotected.

To safeguard these components against external threats such as dust, rain, hail and extreme levels of heat, enclosures are required. This is integral to ensure the smooth working of the electrical devices without potential interruptions caused by damages.
