In CAD section, the 3D model of the 20Mn Turn Cylinder casting was firstly created by UG software. it was used to determine the casting orientation, parting line, core designing, etc. Then based on modulus theory, then 20Mn Turn Cylinder casting was divided into several ponents by the cutoff function and analysis function in UG software. Afterwards， the mass, Volume, Cooling surface area, modulus， were calculated by Excel software. Finally, according to these parameters,the foundry technology of the 20Mn Turn Cylinder casting was designed by . The above design procedure fully shows the advantages of CAD method in aspects of design efficiency and design precision paring with the traditional method of foundry technology design. In CAE part, foundry technologies were evaluated and optimized by SOLIDCast software. Two foundry technology were designed, and one is with riser,another is riserless. Based on the parison of the filling process, solidification process, and shrinkage porosity prediction, it is obvious that the design with the riser head can eliminate all the defect of the shrinkage.
