Cycle time of a part in injection molding process is very important as the rate of production and the quality of the parts produced depend on it, whereas the cycle time of a part can be reduced by reducing the cooling time which can only be achieved by the uniform temperature distribution in the molded part which helps in quick dissipation of heat. Conformal cooling channel design is the solution to the problem which basically "conforms" to the shape of cavity in the molds. This paper describes the analytical study of cooling analysis of different types of cooling channel designs. The best cooling channel design is also selected on the basis of minimum time to reach ejection temperature, uniform temperature distribution, and minimum warpage of part. "Creo Elements/Pro 5.0" is used to model the case study, its molds, and the cooling circuit whereas analytical study is done using "Autodesk Moldflow Advisor 2013 (AMFA). "

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.
