Comparative Analysis of Automotive Interior Trim Materials Based on Moldflow

Abstract

The influence of different materials on the formability of plastic injection molding has been studied in current work. The automotive glove box trim cover was chosen as analytical model. This study has been focused on the influence on fill time, warpage, sink mark depth and clamp force of different materials. PP+T15, PP+T20, PP+T25, PP+T30, PP+T35, PP+T40 and ABS+PC were used for analysis in this study. The injection molding processes of automotive interior trim of different materials were analyzed by using Moldflow software, the rationality of the material choice was evaluated. Merits and drawbacks of different materials were found out through the analysis done in Moldflow. There is positive influence on reducing mold cycle and negative influence on advancing the dimension stability of part by using the kind of PP materials. Oppositely, there is negative influence on reducing mold cycle and positive influence on advancing the dimension stability of part by using ABS. It can be reduce extremely the cost for manufacturing the mold, and shorten the development cycle by using this method.

The Effect of Size on the Mechanical Properties of 3D-Printed Polymers

“…Recognizing this critical gap, the present study is poised to embark on an investigation aimed at characterizing the size effect exhibited by four polymers: polycarbonate acrylonitrile butadiene styrene (PC/ABS), ASA, PLA, and nylon. Each of these polymers holds distinctive applications in a diverse array of industries; for instance, PC/ABS finds prominent utility in blow-molded seatbacks [36] and automotive exterior components [37], while ASA is widely employed in the automotive industry for its excellent performance in exterior applications [38], as well as in the construction sector [39]. Based on initial findings, it has been suggested that recycling PLA has an environmental impact that is 50 times more favorable than composting and 16 times more favorable than combustion, which is considered quite sustainable [40,41].…”

Deformation simulations of plastic parts with consideration of assembly constraints

“…rozstawu otworów montażowych) [4][5][6]. Wynika to z tego, że tworzywa sztuczne mają niższą sztywność, a konstruktorzy oczekują od elementów produkowanych metodą wtryskiwania dokładności niewiele gorszej niż w przypadku wyrobów metalowych [7].…”
