Summary:	由於手機市場的需求趨向小型化，手機鏡頭必須微型化，才能滿足其輕、薄、短、小的需求，其中之光學鏡片更是必須使用雙面非球面塑膠鏡片才能同時滿足其光學性能與外形尺寸的要求。手機塑膠鏡片尺寸的收縮與表面輪廓精度有相當的關係，連帶會影響其光學性能的表現，因此改變成形條件，了解各個條件對塑膠鏡片尺寸收縮量差異之影響，即可透過Taylor Hobson輪廓儀的量測，有效控制其變形量在某一可接受範圍內，以達到所要求之光學性能。本文針對ZEONEX 480R塑料，以不同的射出壓力、射出速度、模具溫度等進行試驗，以了解射出成型品與模具原始尺寸之差異，並配合利用模流分析軟體(Moldex3D)建構3D模型進行模擬分析。由本研究了解壓力對灌口殘留應力有較大之影響；射出速度對收縮率的影響較大，射速快(30/15/12 c.c/s)比射速慢(20/5/2 c.c/s)較不易造成鏡片的收縮；模具溫度較低時(115℃)收縮率較模具溫度高時(125℃)小。 The mobile phone lens emphasizes the microminiaturization now ,the optics lens among them must be used two-sidedly plastic aspherical lens can also accord with light , thin , short , small market demand on the premise of meeting optics performance even more.There are suitable relations between the shrink of the plastic dimension of lens of the mobile phone and precision of form surface profile, it will influence the behavior of its optics performance that related, so change the molding condition , understand that each molding condition shrinks the influence of measuring the difference on the plastic condition of lens, can measure and control through the profilemeter , control its deformation amount when can accept the range in some one effectively, in order to reach required optics performance. This research aims at the test to different packing pressure , ram speed , mold temperature etc., in order to understand that shoots the difference between the shaping product and primitive dimension of mould , and cooperate and utilize CAE software ’Moldex3D” to analyze that the software builds the model of constructing and imitates analysing, study the related and difference among them .
