多组分注射成型与电镀相结合，即所谓的MSG工艺，代表了复制金属微结构的有前途的工艺链。MSG是德语“Mehrkomponenten-Spritzgießen und Galvanoformung”的首字母缩写，英文为“Multi-component Injection Molding and Electroplating”。该工艺基于通过注塑成型高度精确地再现表面细节，以将微结构构建到双组分模板中，并将镍电沉积到该腔体中。这种电镀的微型零件是前一种结构的复制品。为了研究模具嵌件对模制零件和所生产的微型零件的精度的影响，使用铣削的模具嵌件制造测试样本并进行分析。在模具插入物上，对三个微弹簧圈部件（微夹持器的组件）进行微研磨。将介绍各个工艺步骤对最终弹簧圈的表面质量和尺寸变化的影响。它也将显示如何注射成型插入质量的影响所生产的微型零件的尺寸精度。最后，将概述潜在的流程改进。
Multi-component injection molding combined with electroplating, the so-called MSG process, represents a promising process chain to replicate metallic microstructures. MSG is the German acronym of ‘Mehrkomponenten-Spritzgießen und Galvanoformung’, in English ‘Multi-component Injection Molding and Electroplating’. The process is based on the highly accurate reproduction of surface details through injection molding to build a microstructure into a two-component template and electrodeposition of e.g. nickel into this cavity. This electroplated micropart is the replication of the former structure. To study the influence of the mold insert on the accuracy of the molded part and the produced microparts, a test specimen was fabricated and analyzed using a milled mold insert. On the mold insert, three microcoil parts, the components of a microgripper, were micromilled. The effect of the individual process steps on the surface quality and dimensional changes of the final microcoil will be presented. It will also be shown how the quality of the injection molding insert influences the dimensional accuracy of the produced microparts. Finally, potential process improvements will be outlined.
