Why Aluminum Die Casting is Commonly Used?

Aluminum die casting is the most common alloy used for the die casting process today, as it is used in a broad range of products. One of the main benefits of aluminum die cast parts is that it is lightweight, yet withstands the highest operating temperatures among all the die cast alloys. Aluminum also has a very high dimensional stability for complex shapes and thin wall applications. Aluminum die casting parts are chosen for their corrosion resistance and good mechanical properties which makes them a primary choice for a wide range of applications from electronic housing to marine applications. Aluminum die cast parts has high thermal and electrical conductivity as well as EMI shielding makes aluminum an excellent choice for enclosures for networking and telecommunication applications as it provides shielding properties while providing effective heat dissipation for the electronic components housed inside. The lightness of aluminum die cast parts makes them an ideal choice for handheld applications such as power tools and other portable devices and is also used extensively in automotive and aerospace applications for weight reduction and fuel efficiency.  Aluminum die casting parts are also easy to machine for high precision requirements and can be chromated, anodized, painted or powder coated without difficulty.

According to the statements above, aluminum alloy has characteristics below:
1. Light-weight
2. Highest operating temperatures
3. High dimensional stability
4. Outstanding corrosion resistance
5. Good mechanical properties
6. High electrical conductivity
7. Good finishing characteristics
8. Very good strength and hardness
9. Excellent EMI & RFI shielding properties
10. Excellent thermal conductivity
11. Full recyclability

Is Die Casting Simple or Complex?

Die casting could be both simple and complex. Die casting generally uses zinc, aluminum, magnesium, copper, lead, and tin, and now zinc die casting is more widespread.

When it compared to other manufacturing process, die casting could be designed according to customer’s preferences and some special requests. Briefly, die casting is a procedure of molding definite that shapes moulds under high pressure.

Why we say it is simple? Because it could be conclude into a few simple steps.
Mold Lubricant is the first step to control temperature. The next step is to insert the molten metal to the die under high pressure. Keeping pressure until the metal is hardened, then stripping moulds from die cavity. Finally, to clean up the mould’s surface.

Aluminum Die Casting Is Spreading

As die casting products widely used in automobiles, commodities, yachts and other important components, which, everyday, people will get in touch with these products.
Compared to other metal materials, the usage of aluminum casting seems more widely. Some aluminum die casting methods like plaster casting, permanent mold casting and sand casting, are welcomed by the casting manufacturers, for its strengths in fields of price and qualities.
the aluminum casting all can achieve the characteristics of some products, some requirements like certain flexibility, precise size, and individual designs,. And through some practical examples, aluminum casting will be of some less defective and surface defects contrast others.

Development Prospects of Die Casting Industry

Recent years, new alloy die-casting products have been very popular in the market, however, just in the Chinese market. It does not mean it can be so favoured in other countries. So the domestic market is different from abroad. Nevertheless, Luo Baihui, the die casting mold expert, has said that our die casting products can not be going abroad for three reasons:

First of all, there are many shortcomings in using the raw materials which foreign customers cannot accept. What’s more, our country’s die casting production technology is still not perfect. Last but not least, our die-casting mold industry supporting system is not perfect as well.

These points are important obstacles that pressed the globalization of the die casting industry of our country. If we can break through these points, then our hardware products will be reach climax in selling in the international market.

In fact, many people do not know, die and mold are inseparable. Die-casting mold industry comes in to being because they are perfect match.

Die Casting Parts and Its Advantages

Plastics is everywhere in the past few decades. The usage of metal has gradually replaced with plastic products, just like some auto parts, commodities, and so on. While, the products manufactured through the die casting process, and die casting products are usually more durable, when it is compared to other plastic products.      
Whether for products designers, or the manufactures, die casting is a fine choice. Die casting is more suitable for precision parts making. And why is the die casting so durable? In addition to durable materials, die casting parts could resist higher temperatures, or other poor conditions.  
Die casting parts and plastic parts, both of them are the outcome of different economic development phase, and perhaps in the near future, die casting will be replaced with a new manufacturing methods.

Mainstream: Die Casting For the Automotive Industry


The development of die casting industry is always kept pace with automobile industry. During these years around 2000, the automobile die casting usually takes absolute majority of the entire die casting supplies, which always vary from 48 percent to 80 percent.

Of these countries, auto industry in Australia has relied heavily on die casting industry, and America has account for 48 percent, the rest of these auto industry counties are above 50 percent.                  

As is reported, the proportion has already reached to 75, and which will continue for the next few years. Thus it can be seen that die casting industry has accounted for a very important position in modern industry, so does china.

And now, except the common die casting, such as aluminum alloy and zinc alloy die-casting parts, Magnesium alloy and copper alloy die casting have become more widespread.

The Relationship between Die casting and Auto Industry

People are familiar with Auto industry, but few of them have heard die casting before-though it is a pillar industry for the automobile industry. Die casting, zinc die casting, aluminum die casting, even die casting industry, they can easily be found anywhere in our daily life, and most often overlooked.

With the rapid economic development, automotive industry has growing fast, so as the die castings. Just like the automotive industry, die casting have to face the huge challenges on the technology.

Actually, the application of die casting is really closely related to many industrial fields. But, no matter the amount of die casting, or quality, even the material quality, automotive industry has been leading the market. As always, automobile industry is the largest employer, and which will bringing die casting into a new world.


Die Casting is Developing

Die casting was nearly two hundreds years of age when it started. This is a period of history that is long and diversity. Seen from its manufacturing process, it seems quite simple, though the technology of which has been greatly improved.

Die casting is very common to see in the fields of production, and according to current situation, die castings will still be the main production mode in the future. The die casting moulds, is widely used for automotive, commodities, motorcycle parts and others.

Because of the widespread use of die casting, the modern industry has paid much attention on it. And die could shape the die-casting, which is an assurance of quality.

What is Green Die Casting?

As environmental concepts becoming more and more popular, the processes of die casting can also be green, from design to manufacture.

Now, die casting has been attacked by its low environmentally friendly production-it produces much waste solid and waste water. Aluminum die casting is a resource intensive processing, in order to make the surface of products more smooth and beautiful, the extra materials will be removed, and it can be used for recycle.

Green die casting should be low energy and highly effective, what’s more, green technologies could make die castings stronger.

Less pollution, less waste, that is a good vision, and of course, some stress is good, which will lead the control of die casting processes consciously and intentionally.
