Plastic product become more popular adoption in our modern life , the weight of penetration is becoming greater and greater . But there is no any clear defined methodology to check the interaction between injections modeling parameter vs. injections deformation. The article is utilizing Takuchi Method to analyze the injection parameter vs. optical disk deformation (warpage) to see if the optical disk warpage can be improved correctly.
The result shows: there are 4 injection parameters (injection temperature, Injection speed, remaining pressure and remaining time) impact plastic product deformation (optical disk warpage) most. 9 sets of parameter were defined with Taguchi′s L9 Orthogonal Arrays approach then apply to experiments on optical disk injection to get 90 sets of sample (10 of each set of parameter). We got 90 sets of warpage value from measuring 90 sets optical disk sample with 2.5D measurement tool. Inputting 90 sets measuring result to Excel to get mean value and mean STB (the small the best) value. Comparing the mean value and means STB value to equivalent analysis by Minitab , the result shows there is no difference and best parameters are obtained. Injected 10 more sample with optimized injection parameters (injection temperature, Injection pressure, Packing time , Packing pressure) approved the warpage can be reduced around 14.2% 。
