Simulation of Micro-Gear Manufactured by Differential Injection Molding Based on Moldex 3D

Article Preview

Abstract:

In this article, the structure of the differential pump is introduced, which is the core part of the differential injection system. The micro-gear with a shaft collar is simulated as it is an important micro-part and has great potential application in mechanical transmission. The Moldex 3D simulation software is used to investigate effects of processing parameters on the micro-gear such as melt temperature, mold temperature, injection time and packing time etc. By comparing the micro-gear's warpage under different processing parameters, it can be concluded that melt temperature has a greater impact on the molding quality than mold temperature. In addition, the effects of injection time and packing time on the micro-gear's molding quality are also investigated.
