Chapter 8. Hot Embossing Tools

Apart from the molding press (Chapter 7) and the microstructured mold insert (Chapter 9), hot embossing tools are essential components of any hot embossing system. The hot embossing tool may be defined as an interface between the molding press that is responsible for applying the molding force and molding velocity and the microstructured mold insert to be replicated in polymers. Compared to macroscopic molding tools, such as tools for injection molding, where the structures are part of the tool, tools for micro replication are characterized by a reversible integration of a microstructured mold insert. This concept results from the different and incompatible fabrication processes of the macroscopic tool and microscopic ...
