Improvement in Power Efficiency of Injection Molding Machine by Reduction in Plasticization Losses

This paper discusses the losses in injection molding machine specifically in the plasticization phase. Highest power consuming process is identified and a solution is proposed to reduce the losses and transient-thermal Finite Element Analysis (FEA) is performed for verification purpose. The results of analysis are in good agreement with the theoretical calculations. The analysis presented here provides an understanding that how injection system can be redesigned in order to be more energy efficient.
