Warpage optimization on battery cover using Glowworm swarm optimisation (GSO)

Abstract

Injection moulding process is a quite popular process in current industries to produce and replicate a various shape of plastic parts. However, the process involved a lot of processing parameters which is importance to control in order to minimise defect such as warpage. Nowadays, there are a lot of optimisation approaches that can be employed to obtain the suitable processing parameters setting to overcome this kind of defects. In this study, an artificial intelligent optimisation method which is Glowworm Swarm Optimisation (GSO) approach has been carried out to minimise warpage condition. The battery cover was tested with the selected processing parameters of packing time, cooling time, melting temperature, and mould temperature. Based on the Autodesk Mouldflow Insight (AMI) simulation results warpage value is 1.038 mm and GSO approach demonstrated a warpage reduction and the results were 0.931 mm. Thus, by utilising GSO in minimising warpage on the moulded part can be applied in injection moulding sector.
