Advantages and disadvantages of centrifugal casting process for copper bushing

The advantages and disadvantages of the centrifugal casting process for copper bushings are as follows:

Advantages:

Advantages of centrifugal casting of copper bushings 1: Improved material utilisation: Centrifugal casting has virtually no metal consumption from the pouring system and riser system, thus improving material utilisation.

Advantages of centrifugal casting of copper bushings 2: Simplify the production process: in the production of hollow or long pipe-shaped castings, the core can be eliminated, thus improving the metal filling capacity, reducing the ratio of casting wall thickness to length or diameter, and simplifying the production process.

Advantages of centrifugal casting of copper bushings 3: Improve the casting quality: due to the centrifugal force, the casting has high densification, fewer defects such as porosity and slag, and higher mechanical properties.

Advantages of centrifugal casting of copper bushings 4: Suitable for special materials: to facilitate the manufacture of cylinders, sets of composite metal castings, such as steel backed copper bushings, bimetallic rolls, etc.; forming castings, centrifugal movement can be used to improve the filling capacity of the metal, so you can produce thin-walled castings.

Disadvantages：

Disadvantages of centrifugal casting process for copper bushings 1: Problems with bore quality: Inaccurate bore diameter of castings, rougher bore surface, poorer quality, large machining allowance.

Disadvantages of centrifugal casting process for copper bushings 2: Limitations: There are certain limitations when used to produce shaped castings.

Disadvantages of centrifugal casting process for copper bushings 3: Specific gravity segregation problem: castings are prone to specific gravity segregation, so it is not suitable for alloys prone to specific gravity segregation of castings (e.g. lead bronze), especially not suitable for casting impurities specific gravity is greater than the metal liquid alloy.
