There are lots of ways to cast components and just like the method of casting shapes are different, the casting components made from them are not similar. In this article, manufacturers of investment castings India will compare the techniques used by worldwide manufacturing units in the casting process.
Since the ancient time, people have been using this traditional method of pouring molten metal or plastic into a mold to form a shape. After the hardening of the material, it is extracted through the mold and get proper finishing with distinct treatments.
Every casting technique possesses its own unique advantages. However, people prefer an investment casting method more than any other technique, such as lost wax method. If you know the differences between these two methods, you can easily understand the reasons behind such preferences of the people. Let’s discuss it then.
Sand casting
In the sand casting method, manufacturers use silica based material, such as sand, for creating a molding surface. A mold made of sand is a bit flexible, which offers minimum risks like cracking, tearing, etc. as the molten material hardens when cooled down.

This technique possesses some benefits -
- It lowers the production costs
- It lowers the post tooling / finishing costs
- It offers an ability to cast ferrous as well as non-ferrous materials
- It offers an ability to develop large components
Why it is still not a best option to consider?
Sand casting is less accurate methods as compared to investment casting. It is tougher to cast components with predetermined weight and size specifications. Moreover, the finished product has rougher surface finish when it is cast from the sand casting method.

Investment casting
Manufacturers opt for investment casting technique as it is more reliable than any other method. It involves a wax pattern of a product to prepare a mold. Manufacturers dip the wax pattern into a refractory slurry made of materials like silica and POP or Sillimanite and silica to form a mold. After dipping the wax into slurry, they heat the pattern that helps them in melting and removing the wax and hardening of the slurry binders. The molten metal is poured into the mold and set as it is for cooling.

Major benefits of investment castings India -
- Precise production
- Precise dimensions
- Intricate shapes with thin walls can be made
- The ferrous and non-ferrous metal shapes can be made
- Premium quality production
- Finished product
The only drawback of investment casting is that it is expensive than other methods and take longer time to provide results. Still investment casting India is a talk-about subject for every manufacturer and consumer.
