Need of CAPP for Casting

Metal casting is a primary manufacturing process in which molten metal is poured into a disposable or permanent mold to obtain solidified casting of a desired metal composition, strength and quality (accuracy, soundness). Cast parts are found in 80-90% of the manufactured goods. Major families of casting processes include Sand casting, Investment casting, Die casting and Centrifugal casting. Each of these, in turn, can be subdivided into different processes depending upon the type of tooling, molding, core making, melting/pouring, etc. (e.g. sand processes include green sand, shell mould, hot box, cold box, etc.). Each process targets different metals (Ferrous/Nonferrous) and employs different tooling, equipments and process parameters.

Selecting a appropriate casting process and determining its process parameters is a challenging task, needing a detailed knowledge of the process capabilities of various processes and the experience in process planning for a variety of products.

The growing complexities of operating a foundry profitably to produce and supply quality castings in shortest possible lead time, is forcing number of organizations worldwide to look for solutions such as CAPP.
