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.

Techmire Zinc Parts Explained

Techmire die casting machines, one of the major companies servicing the metalworking industry today. They produce die casting equipment for big companies as well as small custom die cast outfits. Operating from Canada, it nevertheless services customers in thirty countries around the world. It is able to take care of the technical concerns of its many clients by way of internet, fax, and telephone assistance through its full after sales service.

Techmire zinc die casting alloy parts are produced in die-casting machines specifically designed for zinc. The company has invented two different sets of machines for this, which they call the NT Series and the NTX Series of die casting equipment for zinc. The NT Series are general purpose, fully automatic, hot chamber, high precision, die casting machines using the multiple slide technology. The three models in this series are the 22 NT, the 44 NT, and the 66 NT. These offer a difference in nominal die size and recommended shot weight.

The NXT Series, on the other hand, complements the older series of NT machines. These new machines for producing techmire zinc parts now include the latest technology such as clamping systems which can handle a higher capacity, extreme pressures, and velocities. This makes the end product have a greater part density and an improved surface finish. The four models in this premium series are the 24 NXT, the 44 NXT, and the 88 NXT. These three machines offer different functions for a range of products. They each offer improved cycle speeds, rigidity, heavier load bearings, the handling of smaller components and larger surface area parts, and other improvements for the making of techmire zinc parts.

Aluminum Shaped

Aluminum Shaped

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.
