Aluminum casting is one of the common casting processes which involves the liquid metal to be poured into a mold or form. In this casting or metalworking process, in place of the liquid metal only aluminum and other relevant alloys are used to be poured into the mold. Aluminum and investment casting in India is used to produce complex and intricate parts in an efficient manner.
The Process of Aluminum Casting
At first, the aluminum is heated to convert into a liquid form and poured into a mold. It should be noted that the mold is made with precision as the quality of the same will have direct implications upon the shape and surface finish of the resulting aluminum casting.
One can make the mold using various materials including tool steel, as the melting point of aluminum is much lower than steel. The mold can also be made out of sand in this casting process. Herein, the sand must be pressed to take shape of the desired finished part. As the sand is formed or shaped, the liquid aluminum can be poured into the same to allow it to be cooled. Following are the advantages which have made investment casting manufacturers in India highly popular:
- Being a lightweight metal, aluminum creates lightweight parts without compromising on the strength of the part.
- Aluminum casting parts are resistant to corrosion.
- It boasts an impressive electrical conductivity rate.
- It has a great strength-to-weight ratio.
- It can be produced in quick fashion and in a cost-effective manner.
- It is completely recyclable and reusable in the production phase.
Applications of Aluminum Casting in India
Due to its light weight properties and lack of difference in product strength, aluminum is preferred for developing different aerospace vehicles that can fly and escape the earth’s atmosphere owing to the light weight. Historically, even the Wright Brothers used aluminum for creating the first wood-frame biplane. Needless to say, aluminum is used extensively in the aerospace industry for various shuttles and structures.
Beverage cans are one of the longstanding markets where aluminum has dominated for years and will continue to do so in the near future. Its printable surface area, recyclability, and conductivity make it an attractive choice in the market. It also helps protect the taste and flavor of the product from any oxygen, light, or any contaminants due to its seal-packed nature.
Construction and Architecture
It isn’t surprising to notice how power grids and electrical transmission lines have shifted their preference to aluminum rather than using copper as the base. This is primarily due to high conductivity and light weight nature of aluminum. It used in large glass panes to handle its weight as strong frames.
In our daily life, we stumble upon various home appliances which are formed from the aluminum casting process. Its thermal properties make aluminum a highly popular and ideal choice for refrigeration of applications. Whereas, the light weight of the same makes sure that the appliances can be moved and placed with ease and comfort. In fact, in the digital arena, aluminum is used for creating various applications. Single blocks of aluminum are used to create the aluminum laptops produced by Apple. Flat screen television sets use aluminum as well for its light weight properties which make it easy to hang on the wall or somewhere else.
Apart from these, aluminum is widely used for other applications as well. Car makers use aluminum for environmental reasons. It is also preferred in the recycling industry due to its reusability nature, especially beverage cans and automobile parts. Aluminum is even used for cleaning purposes nowadays. Needless to say, the number of use cases of investment castings in India are diverse and wide-ranging and it will continue to be used in other sectors as well due to its various advantages.
