2.5. Micro Hot Embossing

The process and technology of micro hot embossing will be briefly described in the following chapters, but for a comparison with the other replication technologies a compact description of this process will be reasonable.

Like the injection compression molding process described above, the hot embossing process also refers to a two-step compression molding cycle, with the difference that the polymer melt is not injected before. Instead of the injection step, the polymer in the form of a thin polymer film is used. This film is heated up via heat conduction up to the melting range before the compression step fills the microcavities. The schematic view of the molding of a single microstructured mold insert is shown in ...
