Frequently Asked Questions

1. How do I know if I need a horizontal or vertical machine to cast my parts?

A general rule of thumb is that a casting that is longer than its diameter is wide is cast using the horizontal centrifugal casting process. An example of this is a tube or sleeve.

Castings that have a wider diameter than length are generally cast vertically. An example of this is a ring. Typically, geometries other than just cylindrical are cast using the vertical process due to mold design complexities.

2. What are the main benefits of centrifugal casting?

The primary advantage of the centrifugal casting process is its increase in yield over static casting or gravity casting. Most castings that can be made using the centrifugal process don’t need gates and risers, which results in better material utilization or yield. Eliminating gates and risers also reduces cleaning time.

Using permanent molds to centrifugally cast a part considerably reduces molding time, core making and setting time.

Higher yields have a side benefit of increasing foundry furnace capacity without adding furnaces. Also, because less metal is being poured to make a casting, associated melt operating costs are reduced.

Other benefits of centrifugal casting are as follows:

  • Directional solidification can usually be controlled with centrifugal casting. This control offers the user a uniform casting. Mechanical properties are nearly equal in all directions and no significant variation in chemical composition exists. With some materials, an increase in density over sand castings is achieved.
  • Castings made using the centrifugal process are generally free of internal porosity caused by trapped particles. This is because slag-oxides and other free particles are usually lighter than the base metal. The difference in density results in the lighter particles collecting on the inner surface of the casting.

3. Do I need a different machine to cast Ferrous and Non-ferrous castings?

No. CCMCO's machines do not care what alloy you pour into them. Different machines are used for both ferrous and non-ferrous castings. The difference will be in the process by which the material is poured, spun, cooled and extracted. CCMCO helps our customers, whether pouring ferrous or non-ferrous castings, successfully produce their castings on our machinery.

4. Does CCMCO supply consumable items required for producing centrifugal castings?

Yes, CCMCO supplies CCMCO supplies our own private labeled coatings using materials such as Alumina, Graphite and Zircon.

We also supply ceramic runner tubes and non-asbestos millboard for use in the foundry.

5. If I have purchased a pre-owned machine on the secondary market, can CCMCO help me get it running and train my operators?

Absolutely. Each one of our machines has a unique serial number, beginning with a J-. If you can send that number we can find all records of your machine and get you some information.

Additionally, we offer start-up and training services among a host of others.

6. Can CCMCO act as an integrator, or Project Manager for large scale projects utilizing Centrifugal Casting?

Yes we can. CCMCO has been involved in many projects in which the centrifugal casting machine is just one part. We can participate in the development of the most efficient design for your plant and provide Engineering services. CCMCO will source robots, induction heaters, among many other things, to provide a complete solution for our customers. Our controls team can integrate all operations and provide a fully automated solution.
