中文摘要 | 本文分別採用田口方法之品質工程規劃法與灰色關聯分析,發展出於塑膠射出成型過程製程中分析不同工程因子對目標品質影響之步驟,並搭配Moldflow MPI模流分析軟體來進行模流分析。將模流分析中所獲得各組合之實驗結果,同時來加以分析並彼此印證其不同工程因子對目標品質之影響,進而求得製程之最佳化加工參數,以減少分析所需之試模時間及成本浪費。本文以CD-ROM碟片托盤塑膠製品為例,以針對其翹曲問題之處理,依據影響剪應力分佈差之各變異因子S/N比變異數情形及其灰色信息關聯度分析後所得結果是一致的,其影響大小分別排列為熔膠溫度、充填時間、充填壓力、模具溫度。另從分析其貢獻率或關聯度上得知其顯著變異因子為熔膠溫度與充填時間,兩者可作為提昇品質之參考。不顯著變異因子則為充填壓力與模具溫度,可作為降低成本之依據。 |
英文摘要 | The article makes use of quality engineering program of the Taguchi method and the grey relational analysis to develop the procedure about the many distinct engineering factors effect the quality of objective on the injection molding process. We also collocates the mold flow analytical software of Moldflow MPI to process the mold flow analysis. Simultaneously, it analyzes and proves the influence of the many distinct engineering factors on the quality of objective each other, from many experiment result of each engineering factor's combination, to establish the optimal process of plastics injection molding in order to execute the effective computer simulation. We take the warping phenomenon of CD-ROM disk pallet for an example, in accordance with the process of variation of signal to noise ratio and the grey relation analysis for each engineering factor upon the distribution of shear stress, acquire that the result for the influences of the objective quality will identically. The arrangement of effect magnitude is the temperature of melt, filling time, filling pressure and temperature of mold. From the degree of contribution or relation we obtain that the noticeable variations are the temperature of melt and filling time. Those factors will increase the quality of product. The filling pressure and temperature of mold, the unnoticeable variations, will be the basis to reduce cost. |
