| Summary: | 碩士 === 逢甲大學 === 智能化機電系統設計產業碩士專班 === 107 === This study aims to save cost efficiently by doing injection molding instead of hot press forming which caused excessive waste. In a traditional shoe factory, mold CAD file is normally held by the mold factory who designed it; therefore, the following sections will focus on how to acquire the CAD file of the model. Before starting the simulation, analyze the required parameters and preliminary estimation; use those values as input in Moldflow to simulate, in order to prevent and improve potential issues.
After simulating the flow process through Moldflow, it was found that there is uneven flow at the outsole. The reason is that the gap on the surface makes the thickness area thinner than expected. There are few ways to improve it. First of all, modifying thickness could be improved. Secondly, increasing the temperature of the mold and material to increase the flow of the raw material. Changing the position of the feed port to reduce its influences can play a role as well. Finally, according to the experimental analysis, found out that the suitable process parameters were mold at temperature 175 ° C, melting temperature 90 ° C, set time 5 seconds, vulcanization time 200 seconds, screw speed 100 mm / s, holding pressure 90 Mpa.
