Analysis of Multi Gating System Using Computational Fluid Dynamics

Abstract

Casting is a manufacturing process for making complex shapes of metal materials in mass production. There are two main consecutive stages; they are filling process and solidification process. Casting process design is important for production quality and efficiency.

Casting quality is heavily dependent on the success of gating system design, which currently is conducted mainly relied on technician's experience. Therefore there is need for the development of a pro-e tool with CFD (Computational Fluid Dynamics) Simulation and Optimization functions to ensure the quality of casting

The objective of the paper is to optimize gating systems based on Pro-e and simulation technology with the goal of improving casting quality such as reducing incomplete filling area, decreasing large porosity and increasing yield in this paper we have conducted the modular experimental setup for studying the flow of liquid in a multi-gate gating System. It consists of a pouring basin, a tapered sprue of square cross section, a runner of constant square cross section and four gates of same area of different cross sections i.e. rectangle, trapezoidal and compared the values with the CFD results obtained.
