Title: Design for Manufacturing Automotive Components
Abstract: This study presents an approach to the plastics part design and tool design optimization, intending to analyze the design parameters, that affects the product quality and molding processes. The proposed method incorporates the mold flow simulation results to characterize the polymer behavior during injection molding process. Computer-aided design (CAD) model was prepared using Pro/ENGINEER software, and analysis was done using mold flow plastic part advisor. The application of simulation programs and associativity of CAD helps to optimize the product geometry and design, and almost remove the usage of preliminary practice of mold trials by verifying the product prior to its manufacture. The part design is analyzed considering critical injection molding process values in particular, polymer melt temperature, mold temperature, injection pressure, packing force, time for filling, etc., with the specified polymer properties. Finally, the part design is optimized to have least defects during injection molding production. It is found that the filling time and shot volume reduced by 8.33% and 6.22%, while increasing the injection pressure and clamping tonnage by 27.9% and 11.2%, respectively. The gate diameter and location have emulated on part standards, attribute and sink marks. Subsequently, the investigation inputs were used to optimize the part design and tool design to save time and cost of molding system design.
