金屬射出成形之模流分析
Mold Flow Analysis on Work piece for Metal Injection Molding
摘要
金屬射出成形是改善一般傳統粉末冶金缺點而發展出來的欣新技術，可用於製造各種複雜形狀之產品，過去影響產品的品質，主要依賴經驗累積與及無數次試誤。本論文探討CAE模流分析之利用，以模擬及數值解析方式，配合實驗去尋找最佳的製程條件與模具設計。從射出成型件常見的缺陷，分析其原因並尋出對策。對於成型製造過程中的入料、充填、保壓、壓縮、冷卻、脫模各階段的參數控制及實驗參數如流道設計、材料、熔膠溫度、充填時間、充填壓力等影響，透過模流分析多維考慮，在品質獲得保證的情況下，以射出成型澆注口壓力最低與產品零件翹曲、變形尺寸最小等，作為評估選擇的指標。經棘輪板手內的制齒成型實例驗證，可以改進以往經驗傳承及試誤的舊程序，滿足目前日新月異的工業界對產品的品質、速度、精確性的要求。

Metal Injection Molding is to improve the shortcomings of conventional powder metallurgy and Yan developed new technologies, can be used in the manufacture of products of complex shape, in the past affect the quality of their products, mainly relies on the experience and the cumulative number of times without trial and error. In this paper, mold flow analysis CAE to explore the use of simulation and numerical analysis methods, coupled with experiments to find the best process conditions and mold design. From the injection molding of pieces of common defects, analysis of its causes and to find out the response. The manufacturing process for forming into the material, filling, packing, compression, cooling, mold release parameters at various stages of control and experimental parameters such as flow design, materials, plastic melt temperature, filling time, filling pressure, such as impact, mold flow analysis through multi-dimensional considerations, to be assured of quality cases, to injection molding pressure pouring mouth parts and products minimum warpage, deformation, such as the minimum size for evaluating the choice of indicators. Ratchet Wrench by the system within the tooth is forming authentication example, you can improve the experience of the past heritage and the old trial and error procedures, to meet the present day abnormal crescent of the industrial sector in the product quality, speed, alcohol does the requirement.
