Design and development of a low cost automation injection molding machine of 250 g capacity using microcontroller

Abstract

This article will describe an innovative way of implementing the automation of an injection molding machine using microcontroller which in turn will reduce total automation cost to only a few thousands rupees. In the piston side, toggle mechanism is used instead of direct drive to get extra mechanical advantage and safety features. The whole design is being simplified by cutting out some features which in turn reduce the total cost of the system without affecting its effectiveness. The system can be operated in two modes. In primary mode, the operator can easily operate through on-board keypad by entering only time sequences with the help of the manual. In the second one, it can be remotely controlled though a PC based application software.
