In the design, the most important one is sureness , calculation of the blank and design of the job spare part of the design plan , this is the key to designing, whether these ones that are designed involve directly or not correctly whether the level of the cost and design mould could work normally。 關鍵詞 :模具設計 壓力機 工藝性分析 模具結構 Summary The speciality of study of our institute is the mold design and speciality of making, the graduation project task this time is lining with a tube of mold design.
