Optimization of Platen for Injection Moulding Machine by Grey Relational Analysis

Now a days, injection moulding machine is the most widely used method for conversion of plastics in to différent end products - for a wide range of plastic materials to specialty engineering plastic. The role of platen plate in injection moulding machine is very important. In this process, compressive stress occurs at regions. As the load fluctuates at a very fast rate, there is a chance of failure of the tie bar road. Due to heavy size and shape, the weight is increased and also it increases the stress levels at regions, and it is not good for the process. This will create failure of the platen plate and failure of tie road due to stretching by nut and platen. This will create wastage of lots of money, man power, material, time, etc., hence the aim of this case is to study about the major areas like stress effect on tie bar and on platen plate deflection. By gray relational analysis we can optimize the platen for injection molding machine.
