Investment casting is also called lost-wax casting and primarily an industrial process that is based on an old method of forming metal. One of the most major developments that have taken place in investment casting in India is foam casting. This kind of casting follows a shorter process because it doesn't follow certain steps required in the complete procedure. This foam casting is ideal for small casts but it is more expensive than die casting or sand casting processes. This old manufacturing process of old wax has been around for over 5,000 years and even Egyptians used it to create gold jewelry. Using lost wax process can even benefit creation of intricate shapes and it can perform such tasks with great accuracy and precision. Hence, it is not surprising that investment casting is also referred to precession casting.
Investment castingsb are commonly used in power generation and aerospace industries. Turbine blades as well as cooling systems are made of it. Some of the common examples of blades produced from the process are directionally solidified, conventional equated and single crystal blades. Even military, medical, automotive and commercial sectors make use investment casts.
This is a process becoming very popular and many investment casting companies have emerged in the market who have been doing the process but to perform the task one should have all necessary equipments like furnaces that can bare high temperatures, proper shape casting equipments, cooling elements that can freeze the cast that can maintain its shape and avoids any fragility of the concluded metal form. Metal casting is mostly used in airlines industry so that stronger parts are attained under a lighter weight. Although, one can find many investment casting companies in the world but one has to choose them very carefully so that any of the future losses are avoided and can run for a longer time as mostly human lives are involved. In simpler words no compromises can be taken under consideration.
Breakthrough in Investment Casting
The use of software is being looked upon as a big breakthrough for the Sand Casting process, something that will considerably optimize injection moulding of ceramic cores and facilitate the design of parts with more complex geometries.
