ABSTRACT

Injection moulding is the most widely used method for the production of intricate shape plastic parts with good dimensional accuracy. The design of a plastic moulding die is of critical importance for product quality and for efficient processing, it is also an integral part of plastic injection moulding as the quality of final plastic part is greatly reliant on injection mould die. The 3D Virtual Model of the moulding die and the core-cavity extraction was performed using the Auto Desk inventor software. The 2D manufacturing drawings were also drafted in Auto Desk Inventor. ANSYS software is used for mould flow analysis and optimum selection of different runner cross section. This work can also be further extended for a detailed stress and fatigue analysis for the core and cavity inserts to obtain better tool life by using ANSYS Workbench. There are various cross sections for the runner of mould design so the best runner cross section is the criteria for the optimization. Here we select the runner cross section by using the analytical hierarchy process.by using this method we arrived at particular solution of the multivariable problem and this method gives the optimum result. The main objective of this of this paper is to develop the relationships among the identified injection moulding parameters using AHP and pair wise comparisons of the element (usually, alternatives and attributes) can be established then can be translated into priority weights (scores).
