1. 背景
最近几年里，在微机系统技术方面具有广泛的研究，普遍认为在未来的十年间微型单元的微机系统和增加对微型设备的应用有很好的发展趋势。分析家预测在未来的几年间微系统技术在设备制造方面将产生深远的影响。
微系统技术还被作为微型机械电子系统技术。微型机械电子系统是用小型机械和电子结构结合在一个系统上来命名的。微机系统技术是80年代出现的，在过的十年里得到了很好的发展，并且被认为将成为21世纪最终要的技术之一。微型化的优点有很多，微电子的成功就很好地证明了这一点。
微型设备的小尺寸使得器械越来越小、越来越紧凑，并且便于携带，同时也能手动作。当各种功能结合在一起时，设备的功能也增加了，比如：感应器、扬声器和控制器被集成在同一微型设备上。由于它们有个高频共振频率，微型机械传感器有个动态范围和快速响应时间。在微小热交换方面能够更加快速、有效地发生，就像一个微型测量设备。
微型机械电子系统现在正处于产品即将进入市场竞争的发展阶段。微型机械电子系统在全球市场的销售额到2002年将达到3.8亿，到2005年将达到5亿。微系统技术的应用领域覆盖了一个很广的范围，从电子学到光学，从化学到生物技术和医疗工程。
而且，微型机械电子系统是个类似于集成电路批量制作的技术。硅晶体是个应用很广的材料。由于大批量生产属性和高额材料费用，硅晶体的一个缺点是昂的价格。
微机系统技术大范围的发展依赖于能够经济可靠地制造成型微小单元的加工系统。聚合体微小化技术，如，微成型技术就是一个低成本生产微小单元的微系统技术。
微成型作为注射成型的一个新分支，目前还处于幼年阶段。它不只是测量某个东西，挑战全新领域的专门技术。成型机械，设备（工具），材料和工艺参数，以及成分的选取与检测都需要特别的研究。
为了面对微型化的挑战，Gintic开始着手通过一个整体程序发展聚合体的微型制造发展核心方面来研究微成型流程的发展。

1. BACKGROUD
There has been considerable interest in recent years in microsystem technology,and it is expected to show continuing expension over the next decade with the trend toward miniaturization of components and increasing applications for micro-devices. Analysts predict that microsystem technology will have a far-reaching influence on device manufacture within the next few years[1].
Microsystem technology (MST) is also described as MEMS technology. MEMS (micro-Electro-Mechanical System) is the name given to the combination of miniaturized mechanical and electronic structures in a system .Started in 1980’s, microsystem technology has become of growing importance over the past decades and is forecasted to be one of the main technologies of the 21st century [2].The advantages of miniaturization are many and the success of microelectronics is a proof of this [3].
The small size of the microdevices makes smaller and more compact apparatus possible and this is promising for portable an hand-held systems [3].The functionality of a device increases when various functions ,such as sensing ,readout and actuation ,are integrated on one microdevice .Miniaturised mechanical sensors ,for example ,typically have a wide dynamic range and fast response times as aresult of their high resonance frequencies .Heat transfer occurs more rapidly and effectively in micro heat exchangers compared to macro-scale device.
MESM is now at a stage where products are expected to enter the market at increasing paces. The total world market for MESM is expected to surge to US$38 billion by 2002[4],and will reach US$50 Billion by the year 2005[5].The application area of micro system technology covers a wide range from electronic to optic ,and from chemical to biotechnology and medical engineering[6-8].
However ,MEMS are typically fabricated with batch-processing techniques similar to those used for integrated circuits. sillicon is still the material that is used in most applications. One drawback of using silicon is high price due to its batch-process nature and high material cost.
The development of microsystem technology on a vast scale is dependent on manufacturing system that can reliably and economically produce micro components . Polymer micro processing technology, e.g. micro moulding technology,is a key enabling technology for microsystem with the capability to provide disposable micro components at a low cost[9,10].
Micro moulding is still veru much in its infancy as a new branch of injection moulding. It is not just about scaling everything down ; it is a specallised technique inits own right , with a different set of challenges. The moulding machine ,tooling ,material and process ,as well as component handing and inspection need to be specially addressed .
In order to meet the challenges towards miniaturization ,Gintic has embark on micro moulding process development through this in-house program to developcore competency in polymer micro-fabrication.
2. OBJECTION
the objection of the project was to develop process technologies for plastics micro injection moulding process permitting cost effective mass production of micro-strutures fom a wide varieties of modern high-performance plastics .
