碩士<br>大葉大學<br>工業工程與科技管理學系<br>95<br>Over time, polymer processing technology has been gradually improved, so that plastic products become the most popular articles in daily life; and injection molding is one of the most important polymer processing technologies, injected products have higher added value, but the manufacturing process still has many complex controllable and uncontrollable factors, as well as time limit. Therefore, it is still hard to make effective online process monitoring so as to minimize change of controllable factor in order to improve product quality. To improve injection

碩士<br>嶺東科技大學<br>科技商品設計研究所<br>100<br>This thesis aims to propose a most suitable process with Taguchi method and Grey Relation Analysis for the bass flute design through injection molding. First, Taguchi method was conducted as the experimental design, The actual performance and Grey Relation Analysis were utilized for collecting data and quantitative processing. Moreover, Factor Analysis was applied to find the optimal parameters from the factor response table and diagram. The results show that the stable audio frequency of the bass flute appears on the molding temperature 50 ℃, the material t

博士<br>國立成功大學<br>機械工程學系碩博士班<br>101<br>Serious adhesion can occur not only during IC encapsulation, but also in the injection molding process. However, while many studies have focused on adhesion during the former, much less attention has been paid to the latter. This study thus developed both ejection mode and tensile mode adhesion force testers to measure the adhesion force that occur during the injection molding process. The experimental results show the ejection mode adhesion force measurement only qualitatively analyzes the adhesion force during thermoplastic polyurethane (TPU) injection

Abstract:

碩士<br>國立成功大學<br>製造工程研究所<br>86<br>Traditional injection molding product development is a sequential process.Geometric model of the product is constructed by the product designer with experience, criterion or guess, but the product designer usually has no enoughknowledge in process development (ex:mold design) and has no genericmethod or aided- tool, which leads to the conflicting problems between thefactors of product design and process development. One of the problemfrequently occurred is e
