Overview of the Injection Moulding Optimisation for Shrinkage Defect

Abstract

The injection moulding process in manufacturing plastic material has become a worldwide used for more than 100 years. The used can be seen everywhere instead of became a daily used product. The complexity of the process makes it difficult to handle but the big production makes it possible to happen. The entire process not just involve the difficult cycling process, but the involvement of the materials which pertaining many types of characteristic which considered to. Every big production need a quality production product with suitable cost and time efficiency. Eventhough, alongside the process, many defects can be detected by the physically seen marks. Many people especially from the expert’s field are trying to minimise as much as they can to reduce the defects so that the residual cost can be minimise. One of the way to overcome the problems is by simulation before the real product is being produce. The simulation is made by two classes of types which classical and non-classical method. Either both of the method gave good result but it still not reaches a perfect solution. In this study, the optimisation method of non-classical and classical are used to minimise the shrinkage defects at the thick plate part.
