Methods for making Aluminum Automotive Parts
Methods for making Aluminum Automotive Parts. Every single day, thousands of aluminum auto parts are made and produced by different auto companies: Chevrolet, Honda, Nissan, Toyota, and more. Many automotive parts are manufactured by net shape to save costs on additional labor and wasted materials. The metal aluminum is often used for car parts or auto parts for they are only a third of the weight of steel parts. Machining holes into the aluminum during production is easier. Indeed, aluminum proved to be the better metal compared to other metals because of its many beneficial properties.
To create aluminum automotive parts, the metal has to first undergo the die casting manufacturing process. First, the aluminum is being liquefied. The liquid metal will then be injected into the molds to take up the shape as dictated by the mold. Around 1,500 PSI to 30,000 PSI is applied, so that the liquid is forced into the mold perfectly. This will ensure accuracy in its dimensions. Afterwards, the molds are set aside to cool and once open, the aluminum automotive parts are perfectly finished.
The end result of this method is extraordinarily amazing: accurate dimensions and great surface finish. Parts can be remade with equal standard and consistency each time.

Enhanced Performance of Cast Aluminum Pistons
Federal-Mogul Corp. reports it has developed a new aluminum automotive piston design that withstands the mechanical and thermal loads produced by heavy-duty engines, making it a more reliable component for diesel engines. This will be important to automotive manufacturers seeking to build vehicles with smaller engines, to achieve lower CO2 emissions and better fuel economy, without compromising the vehicles’ power output.
In a diesel engine, combustion takes place in a hollow bowl in the top of the piston. Combustion temperatures may top 750 degrees F (400 degrees C) and pressures may exceed 200 Bar (200 x atmospheric pressure.) Under these combustion conditions, the rim of the piston bowl has an increased failure factor.
Federal-Mogul engineers identified thermal and mechanical failures factors for the piston bowl, and identified free primary silicon particles distributed throughout the aluminum matrix. Aluminum expands eight times more than silicon, so stresses are introduced within the piston every time temperature fluctuates. Also, the repeated mechanical loads could result in fatigue failure from the corners of the silicon particles.
Silicon cannot be eliminated from the aluminum alloy: It delivers low expansion properties and good castability. A previous solution to the problem is fiber-reinforcement, but fiber reinforcements increase manufacturing complexity.
Federal-Mogul’s new DuraBowl design involves pre-machining the cast piston and then re-melting the aluminum-silicon alloy around the rim of the bowl. Rapid cooling follows, which alters the alloy’s microstructure significantly by reducing the size of hardening phases such as silicon particles and intermetallics.
The result is a piston bowl rim which has its first few millimeters significantly strengthened to withstand temperature and pressure, thereby extending engine life four to seven times what may be achieved with a conventional cast piston.
“The strength and efficiency of our solution is that the process is physically simple,” stated Frank Doernenburg, Federal-Mogul director of technology, pistons and pins. “The sophistication is in the control of key parameters, which ensure consistent quality. The result is a technologically advanced, high-performing and very cost-competitive product when compared to both fiber-reinforced and steel pistons.”

Oil crisis boosts aluminum auto parts use
Oil crisis boosts aluminum auto parts use. There’s a silver lining in the escalating crude oil prices for the aluminum die casting industry. The high fuel prices has renewed consumer demand for lighter, more fuel efficient and environment-friendly cars, prompting the automotive industry to increase usage of aluminum auto parts.
Aluminum now ranks second behind steel among materials used in car manufacturing. Two years ago, the average aluminum content of cars worldwide has already reached close to 280 pounds, with the average in the North American auto industry even higher at an average of 319 pounds. The world average aluminum content of cars in 2002 has been estimated at 274 pounds and at 251 pounds, clearly indicating an uptrend which in the process had aluminum auto parts overtook plastic and iron in usage by the automobile industry.
Reducing the weight of the vehicle is among the primary avenues by which car manufacturers endeavor to reduce the automobile’s consumption of fuel and emission of greenhouse gases. Car Part designers estimate that a 10% weight reduction in automobiles could reduce fuel consumption by 6-8%. If the steel body of a car is changed to aluminum, weight could be reduced by 50%. This in turn would result in an estimated savings of 3,000 liters of fuel and gas emission reduction by 7,500 kilograms during the entire lifetime of the average car. The growing list of aluminum auto parts include instrument support panels, cylinder heads, engine blocks, wheels, front and rear bumper beams, side impact beams, engine sub-frame assemblies, suspension components, roof structures and closure panels.

Die Casted Aluminum Auto Parts
Die Casted Aluminum Auto Parts. Aluminum Auto Parts are becoming very popular among car manufacturers all over the world. Using aluminum has proven to be better compared to using other types of metal such as steel because of its properties. First of all, aluminum as just as strong and durable, if not even stronger and more durable, than steel, secondly aluminum weighs significantly lower than steel of the same size. In fact, Aluminum Car Parts weighs only a third of the same steel parts, making it easier to handle and adding less weight to the car. Aluminum can be mined almost everywhere in the world making it a cheap metal as well. Lastly, Aluminum Auto Parts can be die casted to meet demands for bulk orders.
The manufacturing process known as die casting is perfect for making small sized parts as well as medium sized parts. The finish of the product is amazing as the dimensions are accurate and the surface finish great. In other words, the resulting parts are high standard and consistent each time. This is because Aluminum Auto Parts are made first by liquefying the aluminum. The resulting liquid metal is then injected into molds, its crevices will give the liquid its new shape. Applying pressure of around 1,500 PSI to 30,000 PSI, the liquid is forced into every nook and cranny of the mold. This increases the accuracy of the product’s dimensions. The molds are then set aside to cool for a while and once they are opened, the Aluminum Auto Parts are finished.

Magna to Cut 10,500 Jobs at Opel
The co-head of Canadian auto parts maker Magna said on Sept. 14 that it planned to cut 10,500 posts at loss-making German car maker Opel once it completes its takeover of the General Motors’ unit.
Co-chief executive Siegfried Wolf said his group, which agreed last week to buy a majority stake in Opel from General Motors, was sticking with plans to cut jobs at Opel and its sister brand Vauxhall in Britain.
He confirmed figures reported over the weekend in the German media but said Magna had not modified its terms since late May, when it first signed a memorandum of understanding with GM on the deal. “Our plans haven’t changed since May 31,” Wolf said at a briefing in Frankfurt ahead of the international auto show.
Previously, the figure reported was 10,000 job cuts. The Opel business, including Vauxhall, employs some 50,000 workers across Europe.
Wolf did not say where the job cuts would be made, a sensitive topic as Germany gears up for national polls on September 27.
German Economy Minister Karl-Theodor zu Guttenberg told the newspaper Bild am Sonntag that he believed the cuts were deeper than those estimated earlier by Magna.
Wolf stressed that Opel could be made profitable again by 2015 and dismissed allegations that Magna would invest 600 million euros (US$870 million) of German taxpayers’ money in Russia.
Germany has extended a bridging loan worth 1.5 billion euros to keep Opel going until the takeover is completed, along with loan guarantees worth another three billion euros to get the new company started. Other European Union countries with Opel plants, such as Britain, Poland and Spain, are worried that Germany’s generous aid may mean German jobs take preference and that it could breach European Union rules on state aid. Germany is seeking support from the other countries meanwhile to eventually reduce its own contribution.
