Used Aluminum Die Casting Machines!
Aluminum die casting machines are used for aluminum and aluminum alloys and major manufacturers include: Agrati, Buhler, Colosio, Frech, HPM, Idra, Italpresse, LK Machinery, THT, Toshiba, Toyo Machinery, Ube, Weingarten, Yizumi and Zitai.
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter and tin based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs, and this tends to limit the process to high volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium sized castings, which is why die casting produces more castings than any other casting process. Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.
Aluminum is primarily used to produce pistons, engine and body parts for cars, beverage cans, doors, siding and aluminum foil. It may also be used as sheet metal, aluminum plate and foil, rods, bars and wire, aircraft components, windows and door frames. The leading users of aluminum include the container and packaging industry, the transportation industry, and the building and construction industry.
Aluminum is almost always alloyed, which markedly improves its mechanical properties, especially when tempered. For example, the common aluminum foils and beverage cans are alloys of 92% to 99% aluminum. The main alloying agents are copper, zinc, magnesium, manganese, and silicon (e.g., duralumin) and the levels of these other metals are in the range of a few percent by weight.
One important structural limitation of aluminum alloys is their fatigue strength. Unlike steels, aluminum alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.
Aluminum alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminum alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.
Aluminum Helps Green the Planet
Much of aluminum’s contribution to reducing emissions, fuel use, and energy consumption comes during a product’s lifespan, particularly in aluminum’s largest end market: automotive and transportation. Aluminum’s light weight, combined with its durability, can result in dramatic energy and emissions savings.
Studies recently undertaken by the International Aluminum Institute show just how dramatic those savings can be. Among their findings:
A doubling of the aluminum tonnage in cars worldwide between 2000 and 2010 will curb greenhouse gas emissions by 180 metric tons annually.
The use of one pound of aluminum in place of 1.5 lbs. of steel in a typical bus or truck application reduces greenhouse gas emissions by almost 90 lbs over the lifetime of the bus or truck.
Use of one pound of aluminum in place of 1.6 lbs. of steel in a typical railway car reduces greenhouse gas emissions by almost 450 lbs. over the railcar’s lifetime.
Assuming that 12 billion lbs. of aluminum is used to replace denser materials, the potential savings in greenhouse gas emissions over the lifetimes of those vehicles would be approximately 240 billion lbs.
Our goal here is to assist manufacturers the world over to find valuable equipment - used, pre-owned, or second-hand Aluminum Die Casting Machines- which will enable them to economically expand their production of this valuable metal and so contribute to our world's progress.
On the pages of this site, we hope to help you with your due diligence in researching and selecting the Used Aluminum Die Casting Machines which you may need or require.
