Abstract
Plastic injection parts with fiber reinforce always use for applications of high-strength injection parts and sometimes for replacement of metal parts. However, part surface problems were concerned due to limitations of material property, fiber orientation in plastic parts, and improper injection conditions. This research aimed to study the process parameters that affected fiber orientation and color intensity of plastic parts. Taguchi method was applied for the design of experiment (DOE) to analyze the results of average fiber length and color intensity for the injection part. The main parameters which were melt temperature, mold temperature, and injection pressure were investigated as injection condition settings in DOE. Plastic flow analysis software was used for the investigation of average fiber length and colorimeter equipment was used for color intensity indicating. From the results, the parameters that affected highly to average fiber length and color intensity were injection pressure and mold temperature respectively. The average fiber length and color intensity results after improvement with the Taguchi method were 75.62 % and 23.12 respectively.
