INDUSTRY TRENDS
Practice and advantages of two conventional ways of centrifugal casting

In industrial production, centrifugal casting is usually achieved by volumetric method and weighing method. These two kinds of precautions are not only different in operation process, but also have different advantages. Which one is better? Further analysis is needed to know.

The so-called volumetric method is to use the short runner to cast the corresponding size of the casting, and the volume of the pouring liquid is quantitative. In order to improve the quantitative accuracy, the corresponding ladle will be designed before centrifugal casting, and its design basis is the casting weight. This kind of ladle used in centrifugal casting by volumetric method has many advantages, such as accurate quantification and good repeatability.

In the weighing method, the metal to be cast is weighed first, and then poured into one time to obtain the ideal casting. In this process, it is necessary to use weighing equipment to obtain accurate effect. Although the two methods are different, the castings obtained are still of high quality, so either method can be used.
