Abstract
Multi-component injection molding combined with electroplating, the so-called MSG process, represents a promising process chain to replicate metallic micro- structures. 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.
