Die Casting

What is die casting ?

A precision casting technique, die casting uses a permanent die or mould, into which molten metal is directly discharged. Along with gravity feed system, metal is consistently forced into the mould under high pressure(we called high pressure die casting process. As per the cost incurred in the designing of dies, tooling and other capital costs are relatively high as compared to other operational costs. The operative costs are low due to the high level of industrialization and the small number of fabrication steps which includes the process of direct pouring of metal into a permanent mould. The major die casting alloys are zinc die casting, aluminium die casting, magnesium die casting, copper, lead and tin.

Design : 
Perfect for bulk and mass production, die casting technology is most appropriate for non-ferrous metals with relatively low melting point of approx 870oC such as lead, zinc, aluminum, magnesium and some copper alloys. The casting metals having high melting point like steel, iron and other ferrous metals lowers die life. Dies are fabricated from two blocks of steel, each including part of cavity, locked and attached together during the casting process. The removable and suspendable cores are used to configure internal surfaces. go to our website to know morealuminum_die_casting

Process :
In the entire procedure, firstly the molten metal is inserted into the die and held under pressure until it cools and dries. Than, the die halves are opened and casting is detached with the help of an automatic ejection system. To assist ejection and improve surface quality, the die is cleaned between each casting cycle, preheated and lubricated. The molded coating material is also applied to preserve the molten metal from conductive and cool veneer of the mould. Often, cooling systems are used to sustain the desired operating temperature.

Types :
In general, there are two basic forms of die casting machines, they are :

  • Hot chamber machines – Also regarded as gooseneck machines, they are usually used with zinc, tin and lead based alloys. These machines depend on a pool of molten metal to feed the die.
  • Cold chamber machines – They are mostly used with aluminum, magnesium, copper and zinc die casting alloys. Also, these are mostly used when the casting alloys cannot be used in hot-chamber machines.

Benefits :

Finishing, cleaning, machining and fabrication costs are very less.

After the set up of estate, operating costs are also very low compared to most other casting processes.

At high level of production, the total cost of castings is also relatively low as die can  maintain very high production rates of approx over 400 shots per hour.

This technique renders high accuracy, consistency and good surface finish with qualitative metal yields.

Provides cleaner work environment and low amount of wastes due to removal of refractory material.

The dimensional accuracy is really outstanding.

Disadvantages :

Start up costing is very high, in addition dies are also very expensive. The dies used in die casting are usually made out of hardened tool steels because cast iron cannot withstand the high pressures die casting involved.

The technique is limited to high-fluidity metals.

Aluminium Die casting is used in order to cover different types of metals by using different types of methods. There are many methods used for aluminum casting and different types of benefits are obtained. With the help of aluminum casting and aluminum die casting it is possible to increase life of metals and these can be used for a long time period with an amazing look and charm of metal.


Different types of methods are used for aluminum die casting. Main thing is to melt aluminum. High temperature is needed for melting aluminum. Special structures are used for melting of aluminum. When aluminum is melted then it is poured on the target metals. Then the melted aluminum is allowed to get hard and it is ready to be used after some time period. There are special containers which are made to be used for melting of aluminum. These structures are available in the market in different shapes and sizes. You are also able to make these structures at home by using the desired ingredients. You have many options in making these structures. If you are going to buy this structure from the market then you have to make selection of the size and shapes. There are many options in terms of sizes and shapes and different types of prices are charged by makers. Working of these structures is also different as some use fuels and some use manual efforts for getting heat to make sure that aluminum could be heated and melted effectively. High temperatures are obtained in these structures and then aluminum is melted and then used on the target metals for casting process.


There are many types of benefits of aluminum casting parts. Mainly this type of casting is done to make sure that the metal can remain safe from corrosion. Atmosphere conditions and moisture is bad for iron and casting can help to protect iron and increase its useful life. Aluminum is able to resist moisture and other harmful effects of environment due to which it can be used on metals through casting. Protective shield is made on iron to make sure that it can be used for a long time period. Aluminum can be casted on iron and make a protective sheet. This protection is in the form of a shining layer which is obtained by using high temperatures. This layer is permanent and good looking along with increasing strength and useful life of metal. Mostly iron is casted with the help of aluminum. This is a cheap process and the user is able to get benefits as the life of iron is increased.


Aluminum can be used for casting of iron and other metals. There are many methods available for this process. With the help of any reliable method the user is able to get benefits as the metal is saved from corrosion and other harmful effects of the environment. A protective layer is made as a result of casting and this layer is of aluminum. With the help of this layer the metal can be used for a long time period.
