Purpose of Die Cast Aluminum Heatsinks. Aluminum is the ideal raw material to be used in making heat sinks because this part should be very durable. Aluminum is known to be a more durable metal compared to other metals including steel. At the same time, it is very abundant and easy to acquire which makes it a cheap material as well. Aluminum Heatsinks are used in electronic products and even appliances. Its purpose is to divert the heat produced by the electrical wires from the other more sensitive parts of the product. In other words, it is used as a safety feature to insure that the electrical device or appliance work perfectly and do not overheat.

Aluminum Heatsinks are used in many products all over the world which means that they are needed in large quantities at any given time. To produce them in an efficient and fast manner, the process known as die casting is used.

There are just three simple steps in die casting Aluminum Heatsinks. The first step is to take the aluminum bar and liquefy it by heating the bar. Once the aluminum is turned to liquid, the next step is to inject it to molds or castings so that it will take on its proper shape. When the casting cools, all that is left is to polish it and a few finishing touches.

Die casting can create consistent results in a fast amount of time. At the same time, it is a relatively cheap process which makes it a very popular method in making not just heat sinks, but other aluminum parts as well.

US Industrial production figures for October showed a mixed picture on Nov. 17 as manufacturing output eased after several strong months, Federal Reserve data showed. Output at the nation’s factories, mines and utilities rose 0.1% after an average gain of 0.9% in the prior three months.

Manufacturing output fell 0.1% in the past month, after a jump of 0.8% in September. Factory production had also surged 1.4% in August and 1.2% in July, fueled by rising motor vehicle and parts production and a general pickup in economic activity.

In October, auto production fell 2%, reflecting some of the volatility from the government’s “cash for clunkers” program that spurred buying until the incentives ended in August.

Capacity utilization, a sign of slack in the industrial economy, moved up 0.2 percentage points to 70.7%. This is 10.2 percentage points below its average for 1972 through 2008.

Even with the latest rise, industrial production is down 7.1% from a year ago, reflecting the deep recession that has caused industries to slash output.

“This squares with other data in suggesting that the early quarters of the economic and manufacturing recovery will be constrained by issues related to the sources of demand. Since June, manufacturing output gains have been catalyzed by the normal inventory cycle, in which a leveling of the rapid depletion of stocks requires positive output adjustments, and by a range of fiscal policy programs which provide only a temporary stimulus,” said Cliff Waldman, Economist for the Manufacturers Alliance/MAPI.

“But going forward, stubbornly high unemployment, historically low capacity utilization, and an uneven global economic recovery will prevent consumer, business, and export demand from producing as strong a recovery as might be expected following such a deep and risky economic and industrial downturn,” he added. “The weakness in the October production report was notably widespread with both business equipment and consumer goods industries showing slippage, the latter even beyond the expected retrenchment of policy-induced auto output gains. Such data suggest a modest manufacturing recovery for 2010, with factory output growth only beginning to accelerate to rates that will begin to absorb the large amount of unused capacity by 2011 and 2012.”

Aluminum Part Types – All You Need to Know. Aluminum die casting need a lot of tools and parts to make the perfect dies. The process has been well known to provide an easy method for many constructors to create the most ideal components to different automobiles and the likes. Aluminum parts types are not that easy to characterize especially for a person who is quite new in the die casting process. Since the system also involves a series of molten metals from copper, lead and zinc, a lot of aluminum part types are needed to come up with the best die that possesses the exact instructions by the client. Cold chambered and hot chambered are just two of the aluminum parts types specifically used for the actual machine in die casting.

In most cases, die casters choose to apply all aluminum part types while die casting. This makes the process more experimental, and can sometimes produce the best outputs at the end of the sessions. However, there is a startling difference between a cold chambered die casting machine from a hot chambered one. For instance, a die caster cannot simply use hot chambered types when dealing with aluminum material. This type of material is more compatible to a die casting machine that is cold chambered. Molds for aluminum die casting may also have parts that do not need cavities. This type of mold greatly differs in price compared to those with cavities.

A lot of the parts sold for aluminum die casting often come with substantial product descriptions to let you determine which of the aluminum part types you are about to purchase like Aluminum Handle Hardware and Aluminum Bracket Hardware.

Chinese Solar Panel Manufacturer to Open Plant in Arizona. Suntech Power Holdings Co. Ltd., a China-based maker of solar modules, recently announced plans to open its first U.S. manufacturing plant, near Phoenix.

The plant will have an initial production capacity of 30 megawatts and is expected to begin production in the third quarter of 2010.

The Suntech plant will employ more than 75 full-time workers at launch and may double its staff within the year if the North American market grows as expected, according to the company.

Suntech said it selected the Phoenix area “because of Arizona’s leadership in research through Arizona State University, and statewide renewable energy policies, particularly its Renewable Energy Standard and distributed generation set-aside, as well as a supportive local business climate represented by the Greater Phoenix Economic Council.”

‘Long-Term, Strategic Investment in the North American Market’

Locating the plant close to Suntech’s U.S. customers will reduce the time, costs and emissions associated with long-distance shipping of Suntech panels, the company said.

“This is the first step in what I see as a long-term, strategic investment in the North American market,” said Suntech Chairman and CEO Zhengrong Shi. “Over the last two years we have grown our U.S. team to more than 60 employees. As a result of that effort, we have developed a network of more than 200 solar dealers and integrators installing Suntech products and are actively involved with a number of large-scale solar project developers serving the utility market.

“We also have developed strong partnerships with U.S. companies such as MEMC of Pasadena, Texas, our largest supplier of silicon wafers used in our modules. The leadership shown by the U.S. government in advancing renewable energy will only improve the environment for further investments in the coming years.”

Tooling to Die Cast Magnesium. Die casting magnesium is a difficult but rewarding process for a manufacturing company. Its advantages greatly outweigh its disadvantages, so more manufacturing companies are turning to die casting for their processes to go smoother and more efficiently. Now, even more companies are asking how to die cast magnesium.

There four major steps in die casting magnesium. First, the mold to be used for the die casting process is sprayed with lubricant to control its temperature, and then sealed. Second, molten magnesium is shot into the die cast mold under high pressure, and this pressure is maintained until the cast has become solid. Third, the die is opened and the shot is removed from the mold by ejector pins. Lastly, the scrap is separated from the castings.

Die casting magnesium needs special equipment, of course. For magnesium, cold-chamber machines are used. The magnesium is melted in a separate chamber before being fed into the cast. This takes a longer time than using its counterpart, the hot-chamber machine, where pools of molten metal are utilized. However, since magnesium has a very high melting point, it would be much more difficult to use this machine.

When manufacturing companies ask how to die cast magnesium, they do so because they know the benefits of die casting for their companies. It is very complicated, but every company will benefit from having magnesium die casts as part of their processes.
