Is Aluminum Die Casting Used to Produce Metal Parts?
Yes, it is a process through which you can accurately produce plane, defined, and textured-surfaced metal parts. It does this by forcing liquefied metals into a cast form because of the high-pressure systems.
Aluminum has properties that are beneficial for casting, such as; corrosion resistance, mechanical properties, excellent electrical and thermal conductivity. In the Aluminum Die Casting process, you can harden the metals and cast them into desired shapes.
The die casting process is a recyclable technique which you can repeatedly use to produce different die-cast aluminum products and metals. You can produce a variety of accurate and attractive shapes.
Aluminum die casting is an effective process for industries and businesses. This is the easiest process since Aluminum can be melted into the molds to produce the different desired products. This process holds a lot of significance when it comes to creating a variety of metal parts with quality.
What Are The Alloys Used in Aluminum Die Casting?
Some of the alloys necessary for the Aluminum die casting is,
Zinc is a metal that can be easily cast, has high strength, and helpful for long die life. Uses in a hot-chamber machine. It can easily form very thin walls.
Aluminum has unique properties which are beneficial for casting; dimensional stability for thin walls, corrosion resistance, mechanical properties, and high electrical and thermal conductivity. It is a very low dense alloy. It uses in a cold-chamber machine.
Magnesium is able to weight ratio, and you can easily use this metal in the machine. This is a machine-friendly alloy. It has a very low density. You can use this alloy in both hot and cold chamber machines.
Copper has the ability of high hardness, good corrosion resistance, and high strength to approach the steel parts, and high dimensional stability. It has a low die life because of the high melting temperature.
Lead and Tin have high density, and they are helpful for the special forms of corrosion resistance.
How Aluminum Die Casting Process Takes Place?
In the Aluminum die casting process, you can inject the molten metal into a mold with high pressure, which you can call a die. A die casting cycle completes in 2-3 minutes. Aluminum die casting is the fastest technique to produce non-ferrous metal parts.
The following steps are used to create die casting applications.
The first step in the Aluminum die casting process is clamping, which involves preparing two die halves. After the cleaning process, you can close the two die halves and clamp them. During this step, you must have to apply force to the die to keep it secure while you are injecting metal.
The second step is transferring from either a hot or cold chamber machine. The process that you can do in this step is to inject the molten metal with high pressure towards the die. These pressures range from 31,000 to 20,000 psi, respectively. The injection time depends upon the time required to fill all the cavities within the die. The wall thickness and injection time are directly proportional, it means that thick wall needs longer injection time
The third step starts with the molten metal entering in the die cavity. After cooling when the molten metal becomes solid in the cavity, you can see that the final shape of the casting is produced. You cannot open the die until it completely cools down. This ensures that the casting is solidified.
The geometric design complexity requires longer time for cooling just like the wall thickness.
The fourth step is the elapsing of the proper cooling time. After elapsing, the die halves can be opened and ejected from the die cavity. When the casting is ejected then you can shut the die for the next injection.
This is the last step of the Aluminum die casting process. During the casting process, the excess material and flash must be trimmed from the die channels because of the solidification. There is not only one way to do this process. It can be done through one or multiple cavities.
How Can You Classify Aluminum Die Casting Machines?
There are two major classifications of aluminum die casting machines,
Hot-chamber die casting
This technique is one of the types of die casting which uses metals with lesser boiling and melting points (i.e., zinc alloys). In this process, you can melt the metal by giving it the proper temperature. This process needs pressure ranging from 1,000-5,000 psi.
Cold-chamber die casting
This is a type of casting in which the metals which are utilized have high melting points. (i.e., aluminum alloys). The basic function of the cold-chamber machine is a lot like the other chamber. But there is a slight variation in its working. The difference is in the orientation and the structure.
What Are The Dies That Are Used In Aluminum Die Casting?
Two dies are used in Aluminum die casting,
- Cover-die half
This die half have sprue and shot hole that will help by allowing the molten metal to flow into the dies. This die is secured to the stationary.
- Ejector-Die Half
The ejector die has both the pins and the runner. The runner is the way from the sprue/shot hole that goes up to the cavity. Moreover, it is attached to the movable plate.
What Are The Geometric Features of Aluminum Die Casting?
There are a number of geometric features that are very important in creating a model of Aluminum die casting,
- Parting line
- Holes and windows
- A draft allows the other parts to eject easily from the die. This Draft is useful for all the die-cast surfaces when it comes to its proper ejection.
- Fillet is two surfaces attached while having sharp edges. By adding to a die casting, fillets are used to remove unwanted edges and corners.
- The parting line used as a joint that combines two different sides of a mold. Its purpose is to recognize the cover and the ejector’s side of the die.
- Bosses serve as a stand-off to the die casting and mounting points for various parts that are needed to be mounted. They have universal wall thickness for maximum strength of the Aluminum die casting.
- Ribs provide support for designs. They need maximal strength without making any change to the wall.
- Holes and windows’ parameters will grip the die steel during Aluminum die casting.
Is There any Variant of the Process of Aluminum Die Casting?

How to Design Parts in Aluminum Die Casting?
In the Aluminum die casting method, each part of a product that you produce has its genesis. Die casting allows manufacturers to create smooth or textured-surface metal parts. By using cold or hot-chamber, injects molten metal with high pressure into a die at the speed of 60-100 miles per hour.
Aluminum die casting could be a most popular producing method due to the power to make products at high speed. The uses of die casting include toys, sporting goods, vehicles, appliances, heat sinks, and many more applications.
Some of the tips that you can follow to design your parts are,
Parting Lines for Products
The best vital Aluminum die casting design tips is a parting line that produces a contact surface between all the elements. You should follow the following factors while making a parting line,
The customer’s specification regarding the half can build it difficult to position the parting line. The parting line incorporates a lower quality compared to the opposite surfaces.
A parting line can be low in cost, but a broken parting line costs more expensive to re-design.
Some areas are low tolerant, and that they ought to be set to at least one side of the die. The area close to the parting line must not have essential cosmetic requirements as a result the gates and vents are going to be visible.
The inlet should be placed in the parting line to fill the casting properly with molten metal.
The location of cores depends upon the parting line. You should consider the location of the core, size of the diameter, and length of every core.
Knockout pins are also known as ejector pins. The force which is required to knock out the part depends upon the placement of the parting line.
- Location and Formation
A metal can form on the casting and separate die components. A metal may result from the regular operation of ejector pins. You should flash within the design phase and confirm the quantity of metal you should remove.
- Wall Thickness
Aluminum die castings consist of thin-walls. It is very important to design steady walls in this process. It will help the metal to flow smoothly, and it will minimize the chances of distortion from cooling and shrinkage.
- Die Casting Lettering, Symbols, and Ornamentations
You should add piece of writing, logos, trademarks, and different identifications to the casting. You can use two methods to create these identifications.
- The first technique is the use of raised letters which is cost-effective. Through this method, the letterings last longer.
- The second technique is converting letters into components by using protruding characters on the die. This is an expensive technique.
- Cast Surface Finish on Die Cast Parts
To finish, the tooling is determined to finish the surface of the die-cast component. A good finish on the die will make good surface casting parts. You can do this through the following ways,
- Utility Grade
