Abstract

Using the slot gating system

with filling temperature of 590 ℃

mould preheating temperature of 200℃

injection speed of 5m/s

the filling and solidification process of A356 alloy electric field sensor shell were simulated by the ProCAST software to improve and optimize the gating system parameters.The results show that using semi-solid casting in form of the gate with castings tangential

gasentrapment and shrinkage porosity can be decreased to ensure mechanical performance consistency of the electric field sensor

and the overall quality of the electric field sensor is improved.Adopting the optimized parameters experiment

qualified electric field sensor was produced successfully.
