Micro-forming

Large-scale replication of microstructures

The fields of application for micro-forming include structuring of large surfaces and mass production of serial components. In order to guarantee optimum results, the investigations consider components, tools and processes. In micro-forming of metals, glasses and plastics the objective lies in ensuring cost-effective, reproducible and reliable structural transfer using the hot embossing technology.
