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

Gravity Die Casting and its Advantages

We use the method of gravity casting China in manufacturing casting parts from non-ferrous materials such as aluminum or low-temperature alloys. For a wide range of industrial applications in the defense, medical and energy sectors the process is used to create intricately shaped components. It involves pouring molten metal into a pre-formed cast iron block which is fully machined to produce the die under the force of gravity.

Gravity die casting is a form of die casting that is a great option for creating repeatable medium- and high-volume parts. We refer to this process as permanent mold. Compared to high-pressure die casting it is quite different and is used for parts that have higher structural requirements, are slightly heavier, and larger.

In manufacturing, gravity die casting is an effective and versatile means of quickly creating parts. In the case of other forms of die casting, with the help of a mold cavity molten metal is formed into a shape. In producing the same part this method allows a single set of dies to be reused indefinitely. This is fortunate as the cost of the metal dies and casting machinery can be very high. Because of their excellent surface finish and strength gravity casting manufacturer make use of this technique.

Here we will look at the process and the advantages of this technique.

In gravity die casting there are four main steps involved. At first, the two halves of the die are heated and sprayed with a coating before being clamped together.

Premature solidification is prevented with the help of lubrication and it also helps in the removal of the casting.

Into the cavity of the die, the pouring of the molten metal is done. Before it is allowed to cool the metal solidifies at a rapid rate. At last, the die is opened and the removal of cast parts is done.

Compared to equivalent manufacturing processes there are various key benefits which include:

• It offers excellent durability and dimensional stability.
• versatility – we can engineer complex and simple shapes
• high production rates - in a single day many hundreds of castings can be produced
• It helps in the production of smooth or textured surfaces.
• Gravity casting process provides higher tensile strength and improved mechanical properties when compared with sand casting.
