采用两种不同的制造方法来制造具有不同横截面通道几何形状的微泵。第一种是使用复制模塑（REM）的公知制造方法来制造矩形横截面微通道几何形状。第二种，也是使用较少的制造技术，是使用内部制造的手持式微注射成型设备来创建微通道模具。注塑装置被设计用于弹性体室温硫化（RTV）聚合物，与大多数其他注塑机相反，这些注塑机被设计用于热塑性聚合物。注塑模具的底板被用作微通道成型模板。通过将小直径金属丝（150 μm或更小）穿过注塑模具的底板，随后在金属丝凸起的注塑模具模板上粘附并平滑一片薄铝箔，从而形成模塑模板。当相对模制时，模板产生圆形/高斯形PDMS微通道。注塑模具的设计将被呈现，沿着与微型泵的性能指标，如流速，阀门特性，和最大背压可达到每个相应的微型泵通道几何形状的直接比较。
Two different fabrication methods were employed to fabricate micropumps with different cross-sectional channel geometries. The first was to fabricate rectangular cross-sectional microchannel geometries using the well known fabrication method of replica molding (REM). The second, and far less utilized fabrication technique, was to create microchannel molds using an in-house fabricated handheld micro injection molding apparatus. The injection mold apparatus was designed for use with elastomeric room temperature vulcanization (RTV) polymers, as opposed to most other injection molding machines, which are designed for use with thermoplastic polymers. The injection mold’s bottom plate was used as a microchannel molding template. The molding template was created by threading a small-diameter wire (150 μm or less) through the injection mold’s bottom plate, with subsequent adhesion and smoothing of a thin piece of aluminum foil over the wire-raised injection mold template. When molded against, the template produced a rounded/Gaussian-shaped PDMS microchannel. The design of the injection mold will be presented, along with a direct comparison for micropump performance metrics such as flow rate, valving characteristics, and maximum backpressures attainable for each of the respective micropump channel geometries.
