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.

Super Metal

Filed under: Zinc Casting Parts — Tags: , — admin @ 1:05 am

Super Metal. The #1 most abundant metal on earth is aluminum. Then there is iron, magnesium, calcium, and the rest. Aluminum is a widely used metal. Ever since the discovery of electrolysis to extract it from ores made it affordable and practical. Before that discovery in the 19th century, this metal was more expensive than gold and silver. The reason for this unusual phenomenon was that aluminum, though abundant, was hard to produce and therefore expensive to produce. Nowadays, it is a lot cheaper and used in a lot of different applications. Aside from such diverse functions as high-voltage electric lines, food containers, and mirror coatings, this silver grey metal zinc alloy is also in airplanes and automobiles, marine outboard motors, escalators, guitar amplifiers, light fixtures, and typewriters as aluminum cast parts.

Casting methods for aluminum can be chosen depending on what they are to be used for. The metal is so adaptable that it can be shaped or cast using all the processes known to metal. The aluminum casting process is as diverse as the metal’s many applications. Although in pure form it is soft, its alloy is quite hard. The metals suitable to make aluminum alloys are zinc alloy, copper, manganese, and magnesium.

Aluminum part castings use a number of metallurgical casting methods. The molten aluminum is poured into a mold. The mold could be made of sand, plaster, wax, or a stronger metal. These molds are pre-shaped into the desired product. They are strong enough to withstand multiple castings. The different processes of casting are called die casting, sand casting, investment casting or the lost wax process, and continuous casting.

All about Aluminum

All about Aluminum

Aluminum is a widely used metal in our modern world. Imagine a world without aluminum. It will also be a world without silver paints, explosives, glass, ceramics, cans, foils, LED lights, frying skillets, automobiles, airplanes, CPU’s, outboard motors, lawnmowers, escalators, conveyor belts, streetlamps, typewriters, and some dental equipment. All these things have a component of aluminum, as aluminum cast parts or in other forms.

First step in the aluminum casting process is the presence of an original object which a mold is patterned after. The mold could be made out of sand, wax, plaster, or another metal. There are variations within these variations. For example, sand could be dry sand cores or green sand molds. Metal molds could be water cooled or not. Lubricant is placed on these molds before anything else. Next step is the melting of the metal. The molten metal is then poured into the mold and allowed to solidify inside. As it cures, it takes the shape of the mold, copying every little detail. The product is then taken out of the mold. For aluminum part castings, the process is repeated on and on for a number of times, in the mass production of 380 aluminum parts. These parts are then used for building machines or casings of equipment, or they become part of the little details of some ordinary things that we take for granted.

The casting process is also used in applications other than industry, for example, in art. Sculptors are familiar with the aluminum casting process. In fact, one famous sculpture that is made of aluminum casting is the statue of Eros in Piccadilly of London, the U.K. which used the lost wax method.

Processes of Aluminum

Filed under: Cast Parts — Tags: — admin @ 1:01 am

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.
