Summary:	光學鏡片為光電系統與光電產品中最為常見的光學元件之一，應用層面相當廣泛，如手機鏡頭、望遠鏡及投影機鏡頭等等。面對如此廣大的市場，傳統的研磨製作鏡片的方式受到考驗，在精密成型技術之進步，射出成型技術以低成本，高產量及可自動化的優點滿足了高精度及大量生產之需求，已成為現今光學塑膠鏡片加工領域中最為廣泛使用的量產技術。射出成型的光學鏡片的品質主要關鍵在於幾何誤差與殘留應力分佈，本研究主要針對手機鏡頭之非球面光學鏡片進行一模十六穴的分析探討。本文分成兩部份進行：（1）利用模流分析軟體-Moldex 3D對不同的澆口幾何形狀進行模擬分析，再者設計獨立冷卻系統，控制模具溫度，掌控多模穴的成型品質。依分析所提供之數據與圖片結果，作為模具設計的依據。（2）在實際射出實驗的過程中，對模具溫度進行溫度控制，探討冷模壁效應對於殘留應力的影響。由實驗結果顯示，模具溫度越高有助於降低殘留應力。轉寫性部份，利用非球面輪廓儀量測模仁與成品，其成型誤差在3.604μm，由結果比較顯示，轉寫性情況良好。 The plastic optics lenses are difficult to manufacture in processing plasticity area. And they have homogeneous thickness characteristic shrink phenomenon of warping during formation process. It results in difficult to control the good rate in producing multi caves of optics products.This study focuses on the sixteen caves with one model of the non-sphere optic lens of camera. In the fabrication of plastic optic lens, the parameters of shaping conditions and mold design have major influence in this processing.Consequently, it is divided into two sessions to discuss. First of all, we use the mold flowing analysis software (Moldex 3D) to imitate the different runner geometry forms and design the independent cooling system to control the temperature of mould which is easily to control the shaping quality of model’s caves. The output data and picture are used as the basis of mold design. Secondly, the temperature of mold and plastic is controlled separately during the practical process of shooting experiment to clarify the effect of cold mold wall to the residue stress.From the experiment results , raising the temperature of mold will reduce the residue stress. In the writing transformation section, we used the mould and final product are measured by non-sphere rough instrument and the results shown that the condition of transformable writing is quite well.
