3C與生醫產業產品性能不斷被提升，產品的零組件尺寸被導入精密及微形趨勢，利用傳統製造技術生產精微產品是不易辦到。過去使用一種溝道式下料與擠切成形技術，成功地對材料(ψ=30mm T=30mm)進行齒輪零件成形，最終所得到產品品質都能優於傳統技術。技術特點為在模具上設計一道環狀凹槽；成形的初步階段，溝槽對材料局部集中施加極大靜水壓力保持，並抑制減緩材料提早發生破裂至使成品與餘料脫離。基於上述研究特點，新技術設計採以多重式玻璃金屬模具溝道；在成形時胚料接觸玻璃金屬多重式溝道達到潤滑且可保有靜水壓力雙重效益，此設計轉入精微薄管件與微齒輪零件製造成形是具有助益。提案三年期計畫案建立一個新技術知識庫，第一年：多重式溝道金屬玻璃模具設計之有限元素分析與實體模具開發。第二年：多重式溝道金屬玻璃模具設計對熱微擠切薄壁中空體成形研究。第三年：多重式溝道金屬玻璃模具設計對精微栓槽齒輪成形之研究。The 3c/Medical industry product performance is continuously improving, making the use of traditional manufacturing technology to produce delicate products complicated when the component required is high precision and micro size. In the past, by using trough and extrusion cutting technique was successful to produce gear part (ψ=30mm T=30mm) from the work-piece, and the product quality was better than the traditional technology. The technical characteristics are to design an annular trough on the mold. In the initial stage of forming, the trough exerts hydrostatic stresses concentration in the material, and inhibits early fracture of the slow material flow until the finished product is detached from the work-piece. Based on the above characteristics, the new technology design features multi-trough glass metal mold trough, during forming work-piece will contact the glass and metal part of the mold. The metal part will provide the hydrostatic force while glass part will act as lubricant for its low to none friction coefficient. This design is intended for the manufacturing of fine thin pipe and micro gear. The proposal is a three-year plan to establish a new technology knowledge base, the first year: Finite element analysis and mold development of multi-trough metal glass mold design. Second year: Multi-trough metal glass mold design for thermal micro-extrusion thin-walled hollow body forming research. Third year: study on the forming of fine gears using multi- trough metal glass mold.
