Centrifugal casting: what it is and how graphite is used in this process

Centrigual casting is a process where the metal is placed in a liquid state in a rotating container and expelled in direction of the mold.

Centrifugal casting: what it is and how graphite is used in this process

The centrifugal casting is a method that allows you to work with different metals to create new parts through alloys.

It is important to mention that the centrifugal casting characteristics, make the material does not lose any quality; and it is made at high temperatures to give the necessary shape.

Therefore, it is a resource widely used in different industries such as: aeronautics, automotive, construction, foundry, building, jewelry, steel, among many others.

What is centrifugal casting?

It is a process where the metal is placed in a liquid state, in a rotating container to which centrifugal force is applied, that is to say, it runs away from the center to give it the final shape. Since the metal fills with it, all the spaces to give a final finish to the piece.

The centrifugal casting machine depends on the type of technique and molds used, since they can be made of sand or metal and each one serves a specific purpose. For example.

  1. Real centrifugal casting: it is used to create tubular pieces, the molten metal is placed in metal pieces and depending on the speed with which the process is carried out, it will have more or less consistency the metal. It is used to create rings or tubes.
  2. Centrifugal casting: It is used to create pieces with different molds, since the molten material is sent through the centrifugal force, resulting in homogeneous pieces.
  3. Centrifugal casting: is used to create small, complex or geometric parts, since it uses a branch that sends the molten metal in a symmetrical way.

Benefits of centrifugal casting

The five most important benefits of the casting process are:

  1. It gives a very high quality, since thanks to the force applied to each mold, the material is dispersed in the same way.
  2. No material is wasted, because everything is spread in the mold and you no longer need to generate more processes to give them the final shape.
  3. The savings in the time of the process is a lot, because with only one process you can create several pieces.
  4. Different molds are used to give the final finish, and they are metallic. With the use of graphite, these pieces have a better performance.
  5. It accommodates specific needs, since it is possible to create from small to large pieces.

For example, graphite molds for casting have a high resistance to high temperatures, since graphite is an excellent conductor of heat. Casting can be carried out in graphite molds and thus melt gold, silver, precious metals, aluminum, etc.

For jewelry, there is a centrifugal machine that, thanks to its casting, allows you to create jewelry. It is used for products or pieces of different sizes. It should be noted that you can use this process for specific designs, but it is more expensive because you have to create a special mold to create the piece.

Conclusions

Casting is a widely used resource to create different parts, whether they are small, medium or large productions. Since it allows you to use all the material, without wasting anything and with finishes that have the highest quality.

In ESGRAF we have graphite for the elaboration of molds and containers used in this process, as well as customized solutions that we create from the needs of our customers.
