冷間分流成形精微鍛造製程技術

　　電子資訊產品朝多功能、薄型、微型化是全球趨勢，相關裝置及零組件亦隨之精密化，精微鍛造成形技術具高量產、高材料使用率、低成本、品質穩定等優點，運用於微型零件生產，能滿足市場大量的需求。
今年度載具為模數0.15之微齒輪，其製造技術屬於分流方法之精微鍛造成形模具。然而，要完整將材料進入齒形模穴中完全充滿是非常困難的，因為高工作壓力關係。因此本計畫利用模擬軟體DEFORM進行成形製程之模擬與修正；並進行模具設計、製造與零件試鍛，以作為驗證之比較依據。

　　The global trend of 3C and IT products is becoming multi-functional, thinner and smaller, and the devices/ components of the products also becoming miniature. The micro-part forging technology has the advantages of mass production, high yield ratio, low cost and good quality controlled, which can meet the most of requirements for micro parts.

　　 The objective in this year is to develop a micro gear with modulus 0.25. As to the manufacturing of micro gear, the key technique is to develop a micro forging die with divided flow method. However, the complete filling up of material into die cavity with teeth shape is quite difficult because of high working pressure. The purpose of this plan is to use DEFORM to simulate the forging process. The forging dies are designed and manufactured to carry out the forging trial.

喉部患者新福音--非侵入式氣切管發聲裝置

　　由於喉部有腫瘤或外傷的患者，必須進行喉部切除手術。所以，手術後將導致患者無法與一般人正常溝通。這類的患者在手術後，均必需在喉部裝置一氣管造口器以維持日常的進食及發聲。目前市售的氣管造口器，其主要構造由高分子膜、氣管進口管及進食吸管所組成。然而，這些傳統的植入性人工發聲器仍存有許多缺點，例如：長出肉芽組織及易被分泌物阻塞等。

　　鎂合金除了本身有質輕高剛性，且尚具極佳的頻率響應性質，故適合應用於人工發聲器的研發。本計畫結合鎂合金、壓電陶瓷及IC設計研發出音質佳的非侵入式人工發聲器，而應用於醫療產業。此一非侵入式人工發聲器與市售商品截然不同，且更具實用性，將可在醫療產業創造新的商機。

　　The patient has cancer or trauma on the throat that was cut the soundtrack. Hence, these patients can’t communicate with other people. They have to put a tracheostomy tube on the throat. The commercial product has threes compositions such as polymer film, tracheostomy tube and disposable inner cannula. However, there are many disadvantages in the traditional implantation voice prosthesis such as anatomical granuloma and secretion blockade.

　　 Magnesium alloy is equipped with lightweight, high stiffness, low density and excellent frequency response. The frequency response can be applied in the voice prosthesis field. The project combines the magnesium, piezoelectrical ceramic and IC design to increase the sound quality that can be applied in the medical products. The non-implantation voice prosthesis product is quite competitive, as there is no product in the market to contain this feature, and will create new business opportunity.
