DESCRIPTION (provided by applicant): Currently, there is a serious disconnect between macro and micro injection molding industry. Manufacturers' polymer material data sheets that predict the physical and mechanical properties including flow do not predict properties below 0.020" thickness.. Since properties have proven to be non-linear in thin-walled applications, data below 0.020" may not be able to be accurately predicted. Although there are numerous ASTM standards for material property characterization of macro injection molded parts, none exist for micro- molding. The goal of this proposal is to predict the flow of polymer materials into micro cavities with nano volume features. This information will accelerate the design of thin-walled (<0.010") micro injection moldable parts for numerous commercial applications. In order to achieve this goal we will start by creating standards to evaluate the physical properties of materials with wall thicknesses of <0.010". These same standards would be useful in characterizing new enhancements or processes in material science. In Phase I, we will begin to investigate and characterize one such process. We will compare "neat" to "treated" polymer performance in the production of thin-walled micro injection molded samples.

描述（由申请人提供）：目前，宏观注射成型行业之间存在严重的断开连接。制造商的聚合物材料材料数据表预测包括流量在内的物理和机械性能不会预测厚度低于0.020“厚度的性能。准确预测。尽管有许多ASTM标准用于宏观注入模制零件的材料特性表征，但没有用于微型成型的ASTM标准。该提案的目的是预测具有纳米体积特征的微型腔的流动。该信息将加速薄壁（<0.010英寸）的微型注射式可塑零件的设计。为了实现此目标，我们将首先创建标准来评估壁厚<0.010的材料的物理特性”。 。这些相同的标准对于表征材料科学的新增强或过程很有用。在第一阶段，我们将开始调查并表征一个这样的过程。我们将在生产薄壁微型注入模制样品中比较“整洁”与“处理”的聚合物性能。
