Abstract: This paper presents the redesign of a transfer molded tool for producing stacked molded component for power tools and performing thermal analysis for the mould to access on the effect of thermal expansion and thermal stress in the mold. Selected transfer tool material is cold work tool D2 steel. The technique, theory, methods as well as consideration needed in redesigning of transfer molded tool are presented. The model for thermal expansion and thermal stresses due to working of tool at a high temperature is developed and solved using commercial finite element analysis software called ANSYS WORKBENCH. From the analysis obtain the thermal effect on parts of the tool. Provide optimum clearance between sliding part of the tool. Vary the dimension of the plunger and cavity back plate hole as per analysis result In order to operate the tool precisely.

Keywords: Transfer molded tool, Redesign, Thermal analysis.
