Surface Structuring

For polymer surface structuring by replication the processes hot embossing, nanoimprint, thermoforming and roll-to-roll replication are available. In our labs we operate these machines under clean room and/or temperature controlled conditions. Each Machine is optimized for selected tasks so we can adapt processes and technique for a large diversity of requirements regarding structure size, structured area, temperature and materials.
