【正文】 g part of the design parameters of the verification, CAE (Moldflow) analysis, choice the standardmode. Then product plans, mold assembly project plans and major parts of plans by drawing AutoCAD software. The injection molding method can be directly shape once plex shape of plastic products, it is a kind of high efficiency and mass production. Injection molding is the key process equipment production mode. As ascending CAE, injection molding mould design efficiency and quality, also increasingly attention. Key words： Injection Molding； CAE simulation analysis； Moldflow software； Injection Molding 桂林電子科技大學畢業(yè)設計（論文）報告用紙 目 錄 引言
