Some of the points that must be kept in mind during the process of cast designing are as follows:

☛ > To avoid the concentration of stresses sharp corners and frequent use of fillets should be avoided.

☛ > Section thicknesses should be uniform as much as possible. For variations it must be done gradually.

☛ > Abrupt changes in the thickness should be avoided at all costs.

☛ > Simplicity is the key, the casting should be designed as simple as possible.

☛ > It is difficult to create true large spaces and henceforth large flat surfaces must be avoided.

☛ > Webs and ribs used for stiffening in castings should as minimal as possible.

☛ > Curved shapes can be used in order to improve the stress handling of the cast.
