What is the Aluminum Die Casting Process?

Die casting aluminum is a metal part manufacturing method. To produce the appropriate metal pieces, a high-temperature aluminum bar should be heated until it completely melts, and then pressed into the cavity of the pre-shaped mold.

The cool chamber of the casting machine is used in the aluminum die casting process.


The high temperature of the molten aluminum would destroy the machine if the injection mechanism was immersed, as is done with a hot chamber machine while melting aluminum, hence cold chamber machines are used instead.

The melting pot is separated in the cold chamber machine, and the aluminum alloys are then ladled under intense pressure from the pot into the die. It takes some time for the molten aluminum to solidify after being injected.

The aluminum cast item can then be seen by separating the two sides of the mold.


A smooth surface is produced on the final product. Most of the time, the finished products require only minor machining and are ready for shipping immediately. In addition, the die-cast mold is reused to create the same components before it degrades.

What is the best casting for aluminum?

A lot of aluminum parts are produced via the casting method in addition to aluminum forging or aluminum machining. The three most common aluminum casting methods in China are:

1.       Gravity die casting

2.       Pressure die casting

3.       Sand casting.

The best aluminum casting method is determined by various factors, including part structure, aluminum grade, cost, quality, and so on.

Gravity Die Casting

Gravity die casting, sometimes referred to as permanent mold casting, is appropriate for different-volume manufacturing. Gravity die-casting aluminum castings can potentially be larger than die-casting aluminum castings.

Gravity die cast aluminum pieces can weigh up to 10 kg, but sand casting has a cheaper production cost, it is sometimes considered for considerably bigger castings.

After gravity die casting, T6 heat treatment typically helps enhance aluminium castings’ mechanical qualities. If maximal properties are required, a solution is heated to a high temperature, after which it is cooled, and finally aged naturally or artificially.

A356 alloy, A380 alloy, and other aluminum alloys are China’s most commonly used gravity die casting alloys.

Why Pressure Die Casting company for custom metal parts?

Pressure die casting company uses modern technology to make high-quality die casting parts. Melting metal is forced under great pressure into metal molds during pressure die casting. This kind of casting technique is best suited for mass-producing relatively small aluminum parts.

Aluminum castings produced by pressure die casting will always have tight tolerances and excellent surface finishes. Aluminum castings with thin or uniform walls can be created using this method.

Die cast aluminum alloys that are commonly used include A360, A380, and others. The production of aluminum-silicon-copper alloys like A380 accounts for about 85% of all aluminum pressure die castings.

Sand Casting

Sand casting generally refers to creating a casting mold out of the sand.

The first step in this process is to pack sand into a mold that has been formed using a resin pattern that is a copy of the product. Additional sand shapes, known as cores, are inserted into the mold to create internal cavities.

A running system is used to manually feed molten metal into the mold, which is then allowed to cool. The casting is shot-blasted and completed once it has been taken from the mold box.

Sand casting can create aluminum castings of various sizes and intricate geometric shapes quickly and affordably. Nevertheless, gravity die casting or pressure die casting techniques cannot compete regarding surface roughness or dimensional precision.

What the difference is between die cast aluminum and aluminum?

“Die-cast aluminum” refers to aluminum castings produced by high-pressure die casting, whereas “cast aluminum” often refers to aluminum castings produced through the casting process. The main difference between both is the casting technique.

Several casting techniques can be employed, including sand casting, dewaxing casting, gravity casting, low-pressure casting, ceramic mold casting, and gypsum mold casting. On the other hand, the die casting procedure is a form of high-pressure die casting made with a cold chamber die casting machine.

Heat Treatment for Iron Casting Parts

Generally, heat treatment can be used to strengthen cast aluminum castings, while T6 is the most popular technique. Die castings, however, are unsuitable for T6 heat treatment because of the high amount of gas spread densely within them.

This is because the gas in the die casting will expand and be driven out of the casting surface, causing surface damage and making the casting unusable.

As the gas runs out, the dot protrudes, severely damaging the casting’s look and making it unusable.

Aluminum castings are created using two techniques that are a part of the metal mold casting process: aluminum alloy gravity casting and aluminum alloy low-pressure casting. The molds are formed of hot work die steel like H13.

What aluminum is used for die casting?

A few aluminum alloys are regularly used in die casting. Some of them are the A380, A390, A360, A413 and ADC-12 and ADC-1.

The initial and most key step in getting ready for aluminum alloy die casting is choosing the proper alloy. We’ll help you out by providing some suggestions for various qualities of typical die-cast aluminum alloys.

The A390 alloy, for example, has a high hardness and great wear resistance but is less flexible than any other alloy. As a result, they are suitable for uses like automotive engine blocks.

A360, on the other hand, has excellent pressure tightness and corrosion resistance. Moreover, when molten, they have great fluidity. This alloy is perfect for oil pans, controller shells, 5G communication boxes, and other automotive components.

The A380 alloy offers outstanding product and casting qualities. As a result, they are the product of choice for a variety of applications. A380 alloy is used in many different applications, including power tools, furniture, electronic equipment chassis, gearbox cases, engine brackets, and many more.

Aluminum Die Casting Design Guide

These are some extra factors to think about while designing and manufacturing aluminum die casting products. Here are some of them:

Machining Allowance

The term “machining allowance” defines how much stock a manufacturer may take out of a finished die cast part. Little amounts might not be sufficient to complete the project. It is important to ensure optimal mechanical characteristics and density at the casting’s surface during the aluminum die casting process.

Wall Thickness

The 95% of aluminum die casting projects to require consistent wall thickness. Adjust the process gradually if the result demands a range of thicknesses. Thinner walls can assist to save money on materials and make the custom metal part lighter. The component must be consistent throughout, in addition to having the correct thickness.

Assembly Process

Assembling complex custom metal parts requires the use of methods such as welding, threading, and fastening. Complex assembly will demand numerous phases before the process is finished. So, it is important to choose the appropriate techniques during the planning stage because they will impact the final design of the product.

Shrinkage of Material

In aluminum die casting, it’s important to consider shrinkage. Metal will shrink throughout the cooling and solidification process. Its impact can be reduced by designing an aluminum die casting product with thinner portions. Keep in mind that parts of the custom metal part that are thicker are more likely to shrink and develop surface porosity.

Is aluminum good for die casting?

Aluminum is a good alloy for die casting because of its strong thermal and electrical conductivity, good mechanical qualities, and corrosion resistance. Metals made of low-density aluminum are needed for the die casting sector.

How do I make aluminum die casting?

Metal, a die casting machine, a furnace, and a die are all used in the process of die casting. Die casting machines inject melted aluminum alloys into the dies after melting the metals in a furnace. As aluminum is fed into dies as a liquid, it quickly cools and solidifies to form the finished cast item.

What aluminum material is used for die casting?

The special characteristics of aluminum alloys make them suitable for a variety of products. The most popular alloy for die casting is alloy 380.0 aluminum because it may be used to suit a variety of client needs.

What is the difference between aluminum and die cast aluminum?

Die cast is a casting technique that uses high-pressure die casting with raw materials. Cast aluminum refers to aluminum parts created with a casting process done with molten metal.

Die cast aluminum material properties

·         High working temperatures,

·         Exceptional corrosion resistance,

·         Lightweight,

·         Excellent strength and hardness,

·         Good stiffness, and a strong strength-to-weight ratio.

·         Good rfi and emi shielding capabilities.

·         High electrical conductivity and exceptional heat conductivity.

What is the difference between HPDC and LPDC?

Products made by HPDC have outstanding surface finishes and are porous. Nevertheless, LPDC does not cause any porosity within the casting and has an average surface finish.

Why is aluminum not good for die casting?

Aluminum binds to the die’s cores and other components. A poor surface quality on the casting, further cleaning of the casting and/or die, or even scrapping of the casting can all have an impact on manufacturing costs.

What is high pressure die casting used for?

A wide variety of automotive castings made of aluminum and magnesium, including engine blocks, gearbox casings, oil sump tanks, engine mounts, and structural components like cross-car beams, are best produced using high pressure die casting technology.

What is the pressure range for high-pressure die casting?


The pressure range for low-pressure die casting is from 0.7 bar to 1 bar. However, high-pressure die-casting uses high pressure.
