Processes of Aluminum

Some machines, equipment, and modern electronic gadgets are manufactured for worldwide distribution. The manufacturing process requires speed and efficiency at no sacrifice to quality and cost. For products that are composed of aluminum parts, casting is the answer.

The aluminum casting process provides dimensional accuracy, high strength, a light weight, and a good surface finish. Other benefits of aluminum cast parts are its resistance to corrosion and its thermal and electrical conductivity. Aluminum Casting requires the metal to be molten when it is poured into molds. As the aluminum sets or hardens, it then takes the shape and details of its mold. The properties of this metal that make it ideal for all the ways of metal casting are its high melting point, its malleability, and its ductility.

Aluminum part castings are:

  • diecasting, used for small detailed parts with the same thickness all throughout
  • investment casting, for thin walled intricate precision small parts
  • permanent mold casting, for high-volume larger than die casting pieces
  • sandcasting, for larger pieces with complex shapes and varying wall thickness
  • shell mold casting, like sandcasting but with better surface finish, more dimensional accuracy, and higher cooling rates
  • EPC or evaporative pattern casting, for intricate patterns
  • plaster casting, for fine details as well as close tolerances
  • continuous casting, for non-porous casting of round, square, hexagonal rods and other long shaped aluminum products

    • Other metals that are used for similar processes are the low heat metals that include zinc, tin, lead and the high heat metals such as copper, silver, and copper alloys brass and bronze.

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.

Cast Parts Beautiful

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.
