Design of Slot Hood for Plating Process

Abstract

Metal plating is a process to improve the properties of metals, such as shininess, corrosion resistance, and hardness. During the plating process, the chemicals in plating solutions will usually evaporate in the air which is harmful to human health. This research aims to study and design a hood for a plating tank size (width×length×height), of 0.62×1.50×1.00 m. The study assesses the suitability in hood size and drilling characteristic of hood slots which are in front to the section speed distribution. The computer simulation has been used to predict the flow behaviors based on laminar and turbulent flow.  The study found that the increasing of height and depth of hood are not affect the speed of air flow distribution in front of hood. Furthermore, the slot shape of the hood is also not affect as well.  The air flow distribution more regularly when increase the area of hood slot follow longitudinal direction (X). It is found that, moreover, the flow simulation which is suitable for designing the hood is laminar modelling.
