Aluminum die casting housings have various qualities that's made it indispensable in manufacturing process. Ever since the material was put into a mold to give it shape, the product has stayed with us since then. While die casting from various other materials is possible, aluminum is the most used of them all and housing is the biggest form factor build with the material and process. Here we try to explain some aluminum die casting housing applications and why it is used in the first place. Die casting is a process of pouring hot liquid material into a set mold so that the material, when it cools, will take the shape of the desired mold. That is not a new manufacturing concept, some 200 years ago the idea took shape and it has been refined to the point where we use it now. Since die casting has made it giving shapes to metals easy, one the biggest beneficiary has been the housing form-factor. So, here are some of the industries where aluminum die casting housing applications are prevalent.

For example printed circuit boards, power supplies, transformers, etc. The thermal conductivity of aluminum ensures that the heat generated by the components is dissipated quickly, preventing overheating and prolonging the lifespan of the components.
Industrial Applications
Cast aluminum housing are used in industrial applications to house equipment. Such as motor controls, sensors, and power supplies. Aluminum's corrosion resistance makes enclosures ideal for use in harsh environments. In which they may be exposed to dust, dirt, or chemicals.
Automotive Industry
Casted aluminum enclosures are used to contain electronic components. Such as engine control units, sensors, and lighting control modules. Aluminum's lightweight and long-lasting qualities make these enclosures suitable for usage in vehicles. In which weight reduction is critical for fuel economy.
Medical Industry
In the medical business, cast aluminum housing are used to hold electronic medical instruments such as patient monitoring equipment, diagnostic equipment, and imaging equipment. Aluminum's consistent strength ensures that these enclosures can resist the hardships of medical use while still protecting sensitive electrical components.
Aerospace Industry
In the aircraft sector, cast aluminum housing are used to contain electronic components such as avionics equipment, navigation equipment, and control systems. Because of aluminum's lightweight qualities, these enclosures are suitable for usage in aircraft, where weight reduction is critical for fuel economy.
Outdoor and Marine Applications
Cast aluminum housing are often used to house electrical components such as lighting controllers, solar inverters, and marine electronics in outdoor and maritime applications. Aluminum's corrosion resistance assures that these enclosures can endure moisture, sea, and other environmental factors.
Die casting aluminum enclosures are typically made of aluminum alloys, which are a mixture of aluminum and other elements. One common alloy used for die casting is ADC12, which is made up of approximately 85-95% aluminum, 3-4% copper, 1.5-3.5% silicon, and small amounts of other elements such as iron, zinc, and manganese. This alloy offers good strength, excellent castability, and good corrosion resistance. Other aluminum alloys such as A380 and A413 are also commonly used for die casting enclosures, depending on the specific requirements of the application.
Size and weight of the component
Aluminum die casting can create components weighing anything between a few ounces and several pounds. Still, the part's dimensions and weight will impact how the mold is made and the casting process.
Surface finish
It is vital to note that certain elements may impact the surface quality of the entire aluminum die-casting parts. Therefore, consider the final surface finish sought and any additional procedures, like polishing or coating, that might be required.
Part geometry
Some design aspects, such as sliders or central pins, could necessitate preventive measures in the casting procedure. It is crucial to keep these things in mind during the design phase.
Wall thickness
While creating an aluminum die-casting housing, the wall thickness sensation of aluminum boxes is a crucial design component to consider. The wall thickness of aluminum boxes can impact the housing's performance, strength, and durability.
Thicker walls often provide further strength and durability, but the weight and price of the housing are also increased. On the other hand, thinner walls can compromise strength and durability but reduce weight and cost.
Finding an equilibrium between layer thickness and other design elements, such as the housing's shape, its intended purpose, and any weight or cost restrictions, is crucial when creating an aluminum die-casting housing.
Die-casting entails pouring hot metallic material into a mold at high pressure; thicker walls may necessitate higher pressure and longer cooling times to achieve accurate casting.
Hence, it is essential to design the wall thickness so that efficient casting and assembly are possible while maintaining the required levels of strength and durability.
Draft angles
While developing an aluminum die-casting housing, draft angles are a significant consideration. Die-casting vertical walls have a taper called a draft angle, which makes it easier to remove the item from the mold. They prevent the component from adhering to the mold, which could harm both the piece and the mold.
Although the precise angle will depend on the size and intricacy of the object, an aluminum die-casting draft angle is typically between 1 and 3 degrees per side.
While constructing an aluminum die-casting housing, the location of the draft angles is also crucial to consider. The placement of draft angles should avoid affecting the part's usability or appearance. For instance, draft slopes can be positioned on the part's sides or rear, where they won't be seen.
A part's vertical walls must have a certain amount of taper to be smoothly extracted from the mold. Therefore, it's crucial to include draft angles in the design to ensure the appropriate part release and avoid mold damage.
Undercuts
Slots, holes, and cavities that stretch perpendicular to the mold's parting line are called undercuts. It can be challenging to make aluminum castings, necessitating the installation of specialized equipment or a more intricate mold design.
The Casting Processes for Cast Aluminum Housing
Low / high pressure die casting
Low pressure die casting (lpdc) is the casting process that can produce cast aluminum parts at low pressure, typically between 20 psi and 100 psi. In this process, aluminum is melted and then tranferred into a mold under low pressure until the aluminum solidifies. Cast aluminum parts made from this process can achieve good dimensional accuracy even in medium to high volumes. It is particularly suitable for making cast aluminum parts in thicker wall thickness.
High pressure die casting (hpdc), as its name implies, creats cast caluminum parts at high pressure, typically between 10,000 and 15,000 psi. In this process, molten aluminum is injected into a mold under high pressure fastly. By high pressure die casting, thin-walled cast aluminum parts with complex shapes could be made. Besides, it also allows for high volume production. The strength of cast aluminum made in this process is the best among all the aluminum casting processes.
Gravity die casting
Gravity die casting, sometimes referred to as permanent mold casting, involves pouring molten aluminum into metal molds using gravity for permanent cast aluminum production. Molds made of steel or cast iron typically can support useable multiple cycles, which make gravity die casting an economical medium-to-high volume production method. Cast aluminum parts made from this process can achieve improved mechanical properties and finer surface finishes than sand casting method.
Sand casting
As one of the most versatile casting processes available today, sand casting is not limited to make cast steel and cast iron parts, it can creat cast aluminum parts as well. Cast aluminum parts with intricate geometries are usually made in sand casting process, which is challenging by other casting methods. Aluminum sand casting process involves creating a mold from sand mixture, then pouring molten aluminum into it for solification. Next, the mold is broken away to take out the finished cast aluminum part. This process prpvides flexibility on mold design, so it supports both small and large cast aluminum parts with intricate shapes. While the surface is rougher when compared with die casting process.
Finishing processes can be for aesthetic or functional purposes. Below are a few finishing processes you can consider.
Powder Coating
Powder coating is a dry finishing process that involves the application of dry powder on aluminum. On application, the aluminum cast becomes more durable and has better corrosion resistance.
Painting
This is a popular aesthetic finishing process. However, it can also have a functional purpose. It involves applying a layer of paint to the aluminum part. First, the material is cleaned and sanded. Afterward, a self-etching primer is added, and the layer of paint and an optional extra protective layer containing the enamel sealer. Painting can be a means of color addition or improving the material's corrosion resistance.
Electroplating
Electroplating involves coating a material with a thin layer of another material. This process works by electrolysis. Using an electrode, pass an electric current through a solution that conducts electricity (electrolyte). For instance, if you want to copper plate the cast aluminum, you need a copper-based electrolyte and a copper anode with the cast aluminum serving as the cathode. The copper from the plating comes from the copper solution, which the copper anode replaces. This process adds aesthetic and protection to the aluminum cast.
Anodizing
Anodizing is an electrochemical process that converts the cast aluminum surface to an anodic oxide finish that is durable and highly corrosion-resistant. It involves immersing the aluminum cast into a tank of sulfur or chromic acid electrolyte (depending on the type) while passing an electric current through the medium.
