Design&Analysis of Cylindrical Leakage Fixture for Inspecting Sty-Cast Material used in Electrical Devices

The main objective of the project is to Design& Analysis of the leakage fixture for inspecting Sty-cast materials used at connector part of electrical devices. Sty-cast materials are used for potting of electronic components in order to eradicate the shocks and vibrations due to movement of devices. They are also used as the sealing in electrical components for exclusion of moisture and corrosive agents as the devices are used in various temperature conditions. Generally, Sty-cast materials are inspected through water immersion method in which sty cast is inspected by pressurizing it with dry nitrogen gas and then it is dipped in a sump of water so that if there is any leak in the material bubbles start rising up in the water. The main problem in this method is it can not observe the minor leakages& it also requires a lots of Human Effort. In order to overcome this problem we designed a leakage fixture for inspecting Sty-cast materials used at connector part of Electrical components with the help of pressurized Dry Nitrogen Gas (or) Dry Air.
