<![CDATA[The objectives of this research are to investigate the effect of mold temperature variations on the flash formation and weld line, the mold temperature resulting in the rearview mirror case product with optimal quality on the injection molding process of the polypropylene globalene 7533 (PP) plastic product by using simulation software and on injection molding machine. The correspondence between the simulation of the software and the production application in industry on injection molding process for the design of mold temperature of injection molding process of the polypropylene globalene 7533 (PP) plastic product.This research used the descriptive quantitative. The samples of the research were the rearview mirror cases of PS135. The data of the research were gathered from simulations by using the software of Autodesk Inventor 2013 with the mold temperature parameters of 20oC, 30oC, 40oC, 50oC, 60oC, 70oC, 80oC, and 90oC. They were then entered into a table, displayed in the form of graphs, and analyzed.The results of the research are as follows the mold temperature influences the flash formation and weld line, The parameter which is optimal for the injection molding process based on the measurement with the software of Autodesk Inventor 2013 prevails and on the injection molding obtained through the use of machine of HAITIAN HTF 160X exists at the mold temperature of 20oC. The result of simulation by using the software of Autodesk Inventor 2013 is the same as that of the process on the actual injection molding machine. ]]>
