A Closer Look into the Casting Process

A Closer Look into the Casting Process. The aluminum casting process has been around for a long time, and it operates by forcing molten metal, which is aluminum (naturally) under considerably high pressure into a variety of tooling cavities. The end result of this process, which actually takes longer than most people think, is a number of aluminum cast parts. Aluminum cast parts are some of the most coveted cast parts in the metalworking industry, and it is not hard to understand why. Aluminum part castings are unbelievably delicate and intricate in form, detail, and texture, allowing clients to make quality products.

So, what actually happens in the aluminum casting process? First things first – the mold is closed, just after it is sprayed with lubricants, and the cast parts are closely monitored in terms of pressure and temperature. The pressure required to shoot the molten metal into the die is around 10-175 mpa or, in other measurements, 1500-25000 psi. This pressure is maintained until, finally, the mold successfully solidifies. To complete the aluminum casting process, the die is then filled with a high-pressure injection; this is repeated before the entire mold gets the chance to harden.

Aluminum is just one of the chosen metals that can be used in the casting process. Other casting process makes use of non-ferrous or ferrous metals (this all depends on the client’s taste and needs), such as tin, magnesium, lead, and zinc. Nevertheless, the aluminum casting process enjoys a vast market and claims one of the top spots in the list of the metalworking industry’s preferred casting processes. Die Cast Tooling.

Different Types of Cast Parts

Different Types of Cast Parts – The aluminum casting process is one that has become extremely popular over the last decade, although it has been around for many years now. The reason for this is simple: the aluminum casting process offers a number of benefits. Moreover, the process can produce different types of aluminum cast parts, and just what these are we will be discussing in this article.

Basically, there are three casting methods, and they are zinc die casting, sand casting, and gravity-fed casting. Die casting is probably the most popular and the oldest of all three methods. It is also the method that produces aluminum cast parts that have the highest tolerance and the most incredible, fine finish. The process mainly places pressure on the liquid aluminum so that the die cast parts end up more detailed than other cast parts. Die casting is recommended for the production of small to medium aluminum cast parts. Sand casting, on the other hand, is recommended for the production of large aluminum cast parts that require coarser surfaces.

Compared with die casting zinc, the production costs (both pre and post) of sand casting are higher, but the die cast tooling costs are lower. Finally, gravity-fed casting is considered as an intermediate option. Thus, it is recommended for the production of aluminum cast parts in all sizes. The polish or finish of aluminum part castings is as fine as that of the die casting process; the production costs are lower than those of the sand casting process; and the tooling costs are relatively affordable or reasonable.

Aluminum, uses and processes

Companies who specialize in aluminum cast parts usually also offer zinc cast parts. Die-casting is the preferred method for manufacturing small cast parts. The other metals used in casting aside from aluminum and zinc are magnesium, copper, lead, brass, and tin. Other methods aside from the die cast method are the sand cast, the investment cast, the gravity die or permanent mold. These other methods are ideal for different applications of the cast parts. Each casting process has its own pros and cons.

The aluminum die casting part process is just about the same as for these other metals mentioned here. A mold is prepared from an original. The patterns in the mold are to be duplicated by the cast metal. To make this process of aluminum part castings cost-efficient, several copies are to be made with the one mold. Therefore the mold has to be strong enough to withstand numerous repetitions and still come up with quality detailed products with dimensional accuracy, strength, and other mechanical properties. The metal is melted, and there are different melting points for each metal. The molten metal is then poured or force injected into the mold. As the metal hardens or cures inside its mold, it takes the details and the shape of the mold. The aluminum die casting parts are now formed.

These companies in the metalworking industry have their own foundries, machines, and tooling mechanisms. They provide services to a lot of other industries that require metal in their products. Aeronautics, automobile manufacturing, computer and electronics, consumer products, and a lot more modern industries have a use for aluminum.

The secret of the most useful metal in the world

The secret of the most useful metal in the world. It is the 1st metal in terms of abundance, making up about 7-8% of the earth’s crust. Ironically, it has been hard to mine and use this metal for industrial and commercial purposes until the 1880’s and the discovery of cost efficient methods. The Romans and Greeks used it in salt form for medicinal purposes. Bars or ingots of the metal were kept alongside silver and gold and other jewels.

Nowadays, not a gadget, an engine, or an equipment is produced without the help of this metal. Its commercial manufacture is second only to iron. I am talking about the versatile aluminum. Lightweight, malleable and ductile, with high strength, and non corrosive properties; this metal is the darling of the industrial world. Aluminum cast parts are used in automobiles, marine engines, bikes, construction equipment, and kitchen utensils. It is also found in electrical high wires, heat coils, and watches.

The process of aluminum part castings is also the process of other kinds of metal alloys such as zinc, magnesium, and iron. They are sand and die casting, permanent mold and evaporation pattern casting, composite mold and hybrid permanent mold casting, investment and plaster casting. All these methods in the aluminum casting process make this metal available and useful to all.

No matter what kind it is and what it is called, there is a basic process in metal casting. It involves molten aluminum metal which is poured into a mold and left for a while to solidify. The difference lies in the kind of mold used. Die Casting Tooling.

Aluminum analyzed

The world needs such a wide range of products made out of aluminum that some metalworking companies concentrate their businesses solely on aluminum products. Yet even when narrowed down to this one metal, the production activities for said company can be numerous. There is the choice of assembling aluminum die cast parts, powder coating such parts, or perhaps plating them. There is the pressure testing of aluminum products, tooling, mold altering, machining, or casting. More decisions are to be made regarding the aluminum casting process, whether it should be die casting, sand casting, permanent mold casting, or plaster casting. The decision will depend on the design features of the product. Dimension, surface finish, how complex the shape, the mechanical properties and quality needed, and of course the cost factors all come into play. Finally, although a company chooses to exclusively work on aluminum part castings only, the brochure of said corporation would still be filled with hundreds of different products.

This is because the metal aluminum has properties that make it suitable to almost all metalworking applications. Aluminum is malleable, ductile, with good heat and electric conductivity, has a high strength to weight ratio, is non corrosive, and is cheap enough to manufacture. All these qualities make aluminum the #1 metal for industrial applications. Aluminum is found in die cast parts for electronic gadgets, machines, automotive engines, rocket mechanisms, marine products; as well as in day-to-day products like toys and CPU’s. It is also cast to make kitchen utensils like skillets, pots, and pans. High wire electricity uses aluminum. It’s a good thing the metal is abundant in our earth’s crust.
