Get to Know More about the Aluminum Die Casting

Forcing molten metal into a mold, Die casting like aluminum die casting china is a high pressure metal casting process. With a high quality finish, dimensionally accurate precision metal parts are produced by it. Making it perfect for the mass production of products, its ability to produce detailed parts is high. From non-ferrous metals such as tin, copper, zinc, magnesium, aluminum, pewter, and lead, Die castings are made.

Cold or hot chambers are the two methods of die casting. On the type of the part and metal, the process that is used depends. With metals that have a high melting point like alloys of copper, brass, or aluminum, the cold chamber method is used. To metals that won‘t dissolve on being heated, Hot chamber die casting is limited. These metals include magnesium, lead, and zinc alloys.

Offering a broad range of components and shapes, the die casting process used by aluminum die casting manufacturer is economical and efficient. To be visually appealing, Parts produced can be produced and have a long life. They offer designers remarkable benefits.

Complex shapes with close tolerances are produced by the high speed of die casting produces requiring no after production processing. Additional shaping or tooling is not required at all. With high tensile strength, Final parts are heat resistant.

The presence of iron within the alloys is one of the reasons for the limited ductility of aluminum die casting alloys. To minimize soldering (sticking) of the castings to the uncoated and unprotected steel die, the iron is added which occurs with die casting due to the high injection speed used. Its final use determines the kind of metal used in die cast. For truck and automobile parts, Aluminum is used due to its corrosion resistance and light weight, while stainless steel is sued to make medical instruments.

After and during the melting process, Metals for casting must maintain their characteristics and properties. The kinds include:

• Zinc
• Aluminum
• Bronze
• Brass
• Lead
• Tin
• Silicon tombac
• Magnesium
• Carbon steel
• Stainless steel

Benefits

As it takes very little energy to melt, Aluminum is cost effective for aluminum die casting. It is resistant to corrosion and rust. It is lightweight. It accepts surface finishes, conductivity, ensures dimensional stability, and strength at high temperatures. It is also durable and long lasting. Follow us on Twitter

Benefits of Forged Aluminum for Many Applications

In recent widespread publicity on the increasing use of light metals in the transport sector replacing steel has however in a wide range of applications has overlooked the tried and proven technology of aluminum forging. While considering fabrication options available to the designer, it is clear that some of the emerging casting technologies deserve close examination however at low cost the characteristics of a relatively simple forged design often provide the desired weight + strength.

Surface Finish

from very sharp serrations to relatively smooth surfaces, with forging a wide range of surface finishes can be produced and this may be a functional attribute of the part design or facilitate further surface finishing. Some alloys, like 6061, without any further surface treatment at all have desirable anti-corrosion characteristics.

Cost

In applications from the functional perspective where several fabrication options are viable, cost will be a major driver. Generally forging tooling is quite cheaper, for example, high-pressure die cast tooling, and the production rate is higher. To provide desirable heat treatable characteristics, offsetting this is generally higher raw material costs, associated with the necessary alloying of raw materials. Consequently, in highly stressed applications many aluminum forging process are used, although this is not always the case.

Strength

The light (SG=2.7) and common aluminium alloys when forged and heat treated exhibit some mechanical properties that is comparable with many grades of steel. Therefore the strength to weight ratio is far superior.

Forging is always porosity free unlike some casting processes from aluminum forging manufacturer thus allowing relatively straight forward heat treatment processes that significantly improve selected mechanical characteristics. Typical values of 310MPa is attained by lower cost 6061,which is also superior to, for example, A356 (or 601 types) Al casting alloy whether that alloy is semi-solid cast, squeeze cast or gravity cast. With 6061 aluminium, further fabrication by welding is also available hence opening the opportunities for many other applications.
