4 Pieces of Advice That Can Help You Produce a Better Centrifugal Casting

There are four things you can do to produce a better centrifugal casting.


  1. Make sure you have followed manufacturer’s instructions for building the machine foundation. When designing the special foundation for CCMCO machines we do so with an eye for dampening vibration.  Take special care to ensure that you use appropriate grout and make sure your base is level on its foundation.  The difference of just a few millimeters can make the difference between good and bad castings.


  1. Control you Coating Process. Sometimes customers don’t believe us, but coating type and application are two key components to good castings.  If you are getting defects, one of the first things we will ask you about is what coating you are using, how thick are you putting it on your die and how are you applying it.  Coating can be applied too thick or too thin.  It can be too wet or too dry.  Your coating can even be too weak to withstand the turbulence of pouring metal.  We can help you get it just right!


  1. Determine a metal treatment procedure. Degassing your metal before pouring can have a big effect on casting quality.  Do you get pinholes, or blowholes, in your castings?  Depending where these pinholes are located they might be due to insufficient degassing.  One of the first things we will talk to you about is your degassing procedure.  Is it formalized or does it change from shift to shift?


  1. Pay attention to your molds! If you are getting visual and/or audible vibration during a casting cycle, we suggest that you take a thorough look at your molds.  Check each mold to make sure that it was machined correctly and it is not “out of round”. Mold quality, along with an unlevel foundation are two frequent contributors to poor casting quality.
