Gating System Design For 0.67hp Gasoline Generator Piston

Abstract

The design of gating system is key in the production of various engine components. It serves as basis for determining quantity of materials to be used in the manufacture of components during sand casting. The 0.67Hp gasoline generator piston designed to withstand stress and temperature conditions that the generator will be subjected to during operation was manufactured from the assemblage of gating system components. In order to produce effective generator piston the gating system design parameters such as weight of casting, thickness of casting, pattern length, runner size, sprue size and pouring time were designed to be 0.128kg, 4.805mm, 54.86mm, 492.31mm2, 122mm2 and 11.88s respectively. The gating system calculations were used to produce wood pattern, sprue size, runners and mould cavity. From the result obtained it showed that the developed piston was devoid of casting defects. The experimental generator piston produced from the application of the gating system worked effectively in a 0.67Hp generator set. Keywords: Gating system design, engine, casting and sandcasting
