Finite Element Analysis (FEA) Simulation of an Injection Mold for IPR-2E System (Injection Polymer Recycled-Two Stages)

Abstract

The purpose of the study is to evaluate and optimize key aspects of the injection process, including time, pressure, and fill ability, prior to physical mold fabrication. The study uses finite element simulation with SolidWorks Plastic as the computational tool to analyze the performance of two injection channel designs, designated H and TAO. These channels are tested to evaluate several parameters related to the injection process. It was determined that the H channel was disqualified due to the presence of weld lines, which could compromise the integrity of the parts and affect the accuracy of destructive testing. The TAO channel, on the other hand, was found to be highly efficient in filling the cavity, offering optimal process times and excellent final pressures, with no detrimental weld lines. These results support the selection of the TAO channel as the preferred choice for the mold filling process of the IPR-2E system. Thus, finite element simulation is proving to be an essential tool in molding process engineering, conserving resources, improving part quality, and reducing the likelihood of costly defects.
