Centrifugal Casting

Centrifugal casting, also known as centrifugal casting, is a casting method that involves pouring molten metal into a rotating mold. Through this method, centrifugal force can be utilized to assist in filling the mold with metal and help remove porosity and impurities from the casting, thereby improving the density and quality of the final product. According to different application scenarios and technical characteristics, centrifugal casting can be roughly divided into the following categories:
 
 
 
1. * * Horizontal centrifugal casting * *: In this type of centrifugal casting, the mold is placed horizontally. It is particularly suitable for producing long or tubular products, such as steel pipes, copper pipes, etc. Horizontal centrifugal casting can effectively control the uniformity of wall thickness and is very advantageous for producing large-diameter pipelines.
 
 
 
2. * * Vertical centrifugal casting * *: Unlike the horizontal type, in the vertical centrifugal casting process, the mold is installed vertically. This method is suitable for manufacturing circular parts or products that require openings at both ends, such as certain types of valve bodies. Vertical setting makes the pouring process more convenient and also facilitates the removal of non-metallic inclusions.
 
 
 
3. * * Tilted centrifugal casting * *: This is a method between horizontal and vertical, in which the mold is placed at a certain angle of inclination. The inclined centrifugal casting combines some advantages of the previous two, which is beneficial for forming products with specific shapes (such as conical shapes) and can improve the uniformity of material distribution to a certain extent.
 
 
 
4. * * Semi continuous centrifugal casting * *: In this process, molten metal is continuously injected into a mold that rotates continuously but gradually moves away from the sprue position. This method is very suitable for large-scale production of products with the same cross-section but variable length, such as utility poles.
 
 
 
5. * * Special purpose centrifugal casting * *: In addition to the common types mentioned above, there are also some centrifugal casting techniques developed for specific applications, such as high-temperature alloy centrifugal casting for producing aerospace components, composite material centrifugal casting for manufacturing complex internal structural parts, etc.
 
 
 
Each centrifugal casting method has its unique advantages and scope of application. When selecting a specific method, factors such as the characteristics of the parts to be produced, cost-effectiveness, and production capacity need to be considered. I hope this information is helpful to you!
