Investigation on PID parameters for Uniform Temperature Distribution in the oven by Forced Convection using Lab VIEW 8.2

In this modern manufacturing era, the complexity of design procedure is exponentially increasing. This will lead to bring the design challenges in moulding. The quality of the castings produced in the foundry depends on the size and strength of core patterns placed inside the mould cavity. For getting uniform quality and repeatability, all the cores should have uniform strength. Temperature is considered as one of the main parameter for the strength of the cores. For getting uniform strength, the temperature distribution should be uniform inside the oven. The distribution can be controlled by making a control over the temperature and air flow. In this paper, the temperature is controlled by means of a virtual PID controller available in the LabVIEW software. The virtual PID controller will give better control and precision over an ON/OFF controller. For various PID values, the temperature distribution is analyzed for uniform temperature distribution inside the oven by using forced convection.
