Taking a coupling flange as an example

we described design processes from parts

castings to casting mould on the basis of the Pro/E software.The part modeling should take various processing modelings into account during product design

especially a certain sequence and some kills followed in the parts and three-dimensional modeling process in order to ensure the design of the castings and casting mould smoothly.Processing model should be firstly constructed before modeling the casting mould

in which some technological parameters such as core print and drafting angle are set.Then process model was used to separate the outer mould from the core print

which could decrease the potential errors during individual modeling

improving the precision of the mould and shortening the market period of the product.
