| 摘要: | 因應近年來生物醫療科技產品的市場蓬勃發展，產品功能不斷的提升，對於工業產品而言，越來越趨向於輕、薄、短、小的趨勢，材料表面問題及界面之間的特性也越顯重要，若能夠了解其表面及界面的微細結構、化學成分，對於產品開法或產品分析都有相當大的幫助。其中裝載醫療級產品的塑膠圓弧狀之杯體設計，為了同時要達到功能性與快速生產之要求，並符合成本，成為生產技術供應鏈中備受重視的關鍵。
本研究目的在於射出成型技術，以外圓直徑20mm、深度7.6mm之杯狀為例，成型塑料為聚丙烯樹脂，對於內容物水膠（Hydroxyethyl methacrylate,HEMA）而言，接觸面結構將決定內容物放置經高溫高壓滅菌後，底產生沾黏的情況，因此本研究主要分別探討模仁表面設計對於射出成型時的轉寫特性，接著利用表面輪廓儀找出表面粗糙度與沾黏發生率之關係，並以射出成型實驗中，探討射出成型的製程條件對於粗糙度及微結構轉寫率的影響。
利用實驗模具驗證得知，微結構有效轉寫粗糙度範圍0.6~0.9μm，並於製程指標能力具有1.57之水準，並且依照全因子實驗找出最佳射出參數為模具溫度35度、塑料溫度240度、射出速度30 mm/s、鎖模力130 ton，為本次論文實驗最佳射出成型參數。
;ABSTRACT
Since the whole biotechnology industry has been developed and product functions have been improved, the features of industrial products has become lighter, thinner, shorter, and smaller. The issues of material surface and characteristics of interface are relatively important. It will be helpful for product development and product analysis when we understand the surface and interface microstructure, chemical ingredients. In order to fulfill the functionality and production line with high capacity and to achieve cost efficiency, the plastic arc-shaped design blister which contains medical grade product develops the highly valued key factor consequently.
This study focuses on the injection molding technology. Take the arc-shaped design blister container with an outer diameter of 20 mm and a depth of 7.6 mm for example, the injection molding plastic is polypropylene resin, the structure of contact area between the content HEMA lens and the blister container will result in the adherence scale after the content HEMA lens is sterilized by high pressure and heat. Therefore, this study focuses on the copy feature of cavity core surface design in the injection molding process, and then to identify the relationship between the surface roughness and adhesion by surface profiler; moreover, to investigate the impact that manufacturing condition will bring to roughness and the microstructure copy rate in means of injection molding experiments.
Experimental mold verification shows that the microstructure has an effective transfer roughness range of 0.6~0.9μm, and it has a value of 1.57 in the process capability index, according to the full factor experiment, the best injection parameter is. The mold temperature is 35 degrees, the plastic temperature is 240 degrees, the injection speed is 30 mm/s, and the clamping force is 130 ton, which is the best injection molding parameter provided for the system of this paper. |
