Simulation Analysis of Injection Moulding Process for Fidget Spinner

Abstract

The injection moulding process is a widely adopted manufacturing method for producing parts using thermoplastic and thermosetting plastic materials. This investigation focuses on the moulding process of a fidget spinner. It aims to analyse the gate location to minimise defects in the final product. Simulation analysis using Autodesk Moldflow 2012 software is employed to achieve this objective. The 3-dimensional model of the fidget spinner is constructed using Solidwork. High Impact Polystyrene (HIPS) was selected as the moulding material. Various aspects, including the volume shrinkage, air trap, sink marks and weld lines within the Moldflow software, visualise the results obtained. Through this investigation, valuable insights can be gained regarding the parameter settings for reducing defects and improving the overall quality of the fidget spinner during the injection moulding process.
