In this fast developing and revolutionary era, automation of industry have become a necessity. A Programmable Logic Controller (PLC) is a programmable system used for automation. It is a user friendly microprocessor based specialized computer that carries out control functions of many types and levels of complexity. Its purpose is to monitor crucial process parameters and adjust process operation accordingly. In an industrial setting PLC is used to automate manufacturing and assembly processes. This project deals with the automation of INJECTION MOULDING MACHINE using PLC and pneumatic cylinders. Four cylinders are used where each cylinder represents a specific task. The four processes involved here are clamping and de-clamping of the die, opening and closing of vibratory bowl lid, injection of the molten plastic material and then finally ejecting the component. These entire processes are controlled by PLC. The PLC based on the logic given, controls all the operations and performs the task. In a manufacturing environment, where this assembly is done manually would be labor intensive and would cause substantial reliability problems due to operator fatigue and manual errors. Therefore, there exists a need for an apparatus capable of accurately and reliably handling articles, in a manufacturing environment, while substantially avoiding the difficulties which is accomplished by the project with the help of PLC.
