Design and Mould Flow Analysis of Injection Mould for Luggage Bag Wheel - A Review

Abstract

Due to heavy demand in plastic products, plastic industries are growing in a faster rate. Plastic injection moulding begins with mould making and manufacturing of intricate shape with good dimensional accuracy. To meet such requirements it is very important to adopt various advance technologies for the development of injection moulded components. This study deals with Design and Mould Flow Analysis of an automatic plastic injection mould for production of Luggage Bag Wheel. Plastic wheels, commonly used in standard bags, suitcases and are manufactured exclusively by the injection moulding process all around the world. Modelling in done by using Unigraphics (NX 6.0). The material used is Polypropylene (PP) for the outer part and Thermoplastic Elastomer for the Outer cover. Guide bush is used which acts as a sleeve is made by material Derlyin. The elements of injection moulding tool has designed and analyzed. A Design of Experiments (DOE) of the moulding process parameters is used to identify key moulding parameters by analyzing a multi cavity injection system.
