Riser design is an important part of casting process design.In order to save metal materials and reduce production cost

the design principles of riser process were further analyzed.According to the feeding principles and production experience

the riser optimization model was established and transformed into an actual problem model.The riser actual problem model was optimized by using fruit fly optimization algorithm.On the precondition of process requirement

the optimization result shows that the riser volume is reduces by 12.635% compared with calculated by the modulus algorithm

exhibiting a satisfied effects.Compared with the simulated results by HZCAE

the result verifies the feasibility of fruit fly optimization algorithm.
