Aluminum is a metal found naturally in the earth’s crust. It is silvery grey. It is light in weight. It is not a magnetic metal. It does not sparkle but it was once considered more precious than gold. It is abundant but reactive and has to be extracted from ore.

Once extracted, this metal is useful in a wide range of industrial applications. Aluminum cast parts are found in an unbelievable number of our day-to-day appliances and equipment. It is used in car pistons, aircraft components, marine hardware, machine tool parts, lawnmower gear and housings, streetlamp housings, lighting fixtures, typewriter frames, dental equipment, frying skillets, golfing products, guitar amps, and hardware brackets. This metal has certain properties that make it ideal for use in all kinds of metal casting processes. The aluminum casting process include die casting, sand casting, permanent mold casting, composite mold casting, continuous mold casting, investment casting, centrifugal casting, plaster casting, and hot isostatic pressing.

Casting is a way of manufacturing that enables mass production in an easy, affordable manner. It involves the use of a mold, a pattern, release agents, sealers, and die casting alloy material. Viscous substances that can be poured into a mold are perfect for this. When the material sets or cures it takes the shape of the mold. This is how aluminum part castings are processed. Other metals that can be shaped in this way are tin, lead, zinc, copper, and silver. Non-metals used as material are concrete, plastic resins, plaster of paris, and wax.

The Process of Making Aluminum Cast Parts

Filed under: Aluminum Casting Parts — Tags: — admin @ 7:13 am

The process of making of aluminum cast parts entails value for product quality, above else. With this in mind, aluminum casters tend to give premium on following specifications right to the tilt. The basic agenda on the list is die construction, which is primarily made of aluminum casting tooling. Aluminum casting is made of alloy tool steels in at least two sections, namely the fixed die half and the ejector die half. In modern times, dies may carry cores, movable slides, or other sections for the production of threads, holes, and other features for the attainment of the desired shapes.

The fixed die half has sprue holes that makes it possible for the molten metal to enter the die and fill in the cavity. On the other hand, the ejector die half has runners and gates that lead the molten metal right into the cavity. Aside from these two sections involved in the aluminum casting process, dies also consist of locking pins (for purposes of securing the fixed die half and the ejector die half), ejector pins (for purposes of making the removal of the cast part easier), and openings (for purposes of cooling and lubricating the molten metal or cast).

When the chamber closes, the fixed die half and the ejector die half become one and remain locked together, thanks to the chamber’s hydraulic pressure. After a certain amount of time elapses (depending on the total projected surface area and the pressure required for the injection of the metal into the cavity), the aluminum casting process is completed and high quality aluminum castings parts are produced.

Cast Parts Beautiful

Filed under: Cast Parts — Tags: — admin @ 1:03 am

From forcing molten metal under high pressure into tooling cavities, products from and for cast parts are formed. Cast parts, as we know it, is one fine way to produce small to medium sized parts that has good and intricate details, delicately formed surfaces, and that has consistency in dimensions making it as a very welcomed addition in the part production industry.

Now, some of you may wonder what materials are used in this very clever process. With cast parts, raw materials and elements (or non-ferrous metals as they are properly called) like zinc die casting, copper, aluminum casting, magnesium, lead, and tin based alloys are used. These non-ferrous metals, as their collective name suggests, contains no trace of iron. And although these are the materials that are commonly used, ferrous materials (or materials that has traces of iron) can also be used in this process.

And the process itself, you may ask? Well, a cast part begins with closing the mold after being sprayed with a lubricant. By spraying lubricant on the mold, the temperature of the die can easily be controlled and the removing the cast later on will be much easier. After this first step, molten metal that is under high pressure of around 10—175 MPa (1,500—25,000 psi) is shot into the die. This amount of pressure is kept once the die is filled and until it is totally solidified. Filling the die by using a high-pressure injection is done so that the whole cavity would be filled before parts of the entire casting hardens. Moreover, using a high-pressure injection helps makers avoid irregularities in form even if there are parts of the cast that are not easy to fill due to its irregular shape.

And with a process as long as this one, one can be sure that the results will be beautiful die casting parts.

Aluminum Cast Part a Tough Job

Filed under: Aluminum Casting Parts — admin @ 1:44 am

Making aluminum die casting parts using the aluminum cast part process can really be a tough job. Just imagine pouring raw aluminum and zinc materials into molds, melting metal, and a whole lot more. And did I mention that those steps are just the beginning? Aluminum cast part requires more than just pouring metals around.

When the die has finally taken on a solid form, it then must be opened and will then be pinned by the ejector. The gate, runners, and flash, which are collectively known as the scrap, must then be separated from the casting. A special trim die that is in a power press or hydraulic press is often used to do this part of the process. Sawing or separating by hand can also be done but are considered as older methods which will then require case grinding to smooth out the scrap marks. A much easier way, when gates are thin and easily broken, would be to use tumble shots afterwards separation of gates should be done. The metal used in the whole process will not be entirely utilized as 15% of it will be not put to use due to many different factors. Remolding it though would make the metal recyclable.

Definitely, the whole aluminum cast part process takes on a intricate and arduous labor. And although that is the case, people in this industry still prefer to perform aluminum cast parts as it produces rapid production rates and gives various other benefits to the whole production process. Besides, the fine finished products that this process yields are very much worth all the hard work that aluminum cast part requires.

Advantages of Cast Aluminum Parts

Filed under: Aluminum Casting Parts — admin @ 1:09 am

The Cast Aluminum process is used for producing engineered metal parts through employing force unto molten metal put under high pressure in order to make reusable steel dies and molds. These molds are what the metalworking industry generally refers to as dies, and they are designed in different shapes, sizes, and thicknesses in order to meet the specifications of the user.

The demand for die casting aluminum parts has risen significantly as opposed to the consumer reception it obtained when it was first introduced in the middle of the 1800s. There are many reasons for this apparent change in choice in both the sides of the manufacturers and the consumers. The process of casting die is rich in history and over time, the use of die cast parts has become more advantageous compared to the other processes used in the metalworking industry.

Die Casting Aluminum is very versatile. Die cast parts carry amazing dimensional precision and creativity in terms of measurement, mold fit, and net-shape casting. There are a number of choices available as far as the physical appearance of die cast parts is concerned. As mentioned earlier, molds can come out in a variety of shapes, sizes, and thickness. They can be made to complement the visual output of their surrounding parts. Cast aluminum is also a very economical process, primarily because production (pre and post) costs can be cut down effectively owing to the fact that assistance from machines and tools are seldom required in making die cast parts.
