Abstract— In Centrifugal Pipe Casting machine, hot molten metal is injected from one end and the other end remains closed. This covering plate is locked by a worker with the help of a spanner. This covering plate again needs to be opened after completion of casting process for the extraction of the pipe from the mould. The new and improved locking plate is designed by the industry but it is not having any automatic locking or unlocking arrangement. Also after some time covering plate breaks because of high temperature. This project discuss mainly focused on the analysis of the same locking plate designed by the industry by using FEM and its remedies so that the human interference must be reduced to higher extent. Thus large amount of time can be saved which in turn will increase the productivity and reduce the cost of production. The design and analysis of a centrifugal casting lock plate is successfully carried out. The operation of the machine was based on the principle of centrifugal force. Suitable design theory, analysis and calculation were adopted carried out in the course of the work. The centrifugal force on the machine was determined to be around 70 N. A test was carried out on the FEM software’s and design is prepared in CAD package.
