This paper discusses the test process of producing ductile iron pedal with lost foam technology, determines the best pouring method of casting and the formulation and coating process of the coating, analyzes the reasons that the deformation of the pedal castings is easy to produce and the defects that should be taken Measures. The results show that the production of ductile iron pedals by EPPC method can improve the surface quality and dimensional accuracy of the castings and reduce the production cost through appropriate process control.
