Design of a helmet mold project with an injection molding process to provide a simulated picture of a product. The helmet design that will be realized is made of polymer material with an injection molding machine as the main tool. The use of the machine so that time efficiency becomes faster, the mold designed is only in the form of a core and cavity. The software used is Autodesk Inventor 2017 with HDPE (high density polyethylene) material. Making a futuristic helmet product design requires a design style that offers a modern, unique and unusual appearance. The purpose of this design is to be able to design project helmets that are more modern than before. The method used for the design of this project helmet is a simulation of fill analysis, fill time, confidence of fill, quality prediction to show the level of quality of the injection results. The test results of the fill time takes 11.67 seconds, the confidence of the filling capability is 100% filled, and the quality prediction of the product quality is very good 82.1%.
