Deformation Behavior of Glass Nanostructures in Hot Embossing
ACS Applied Materials & Interfaces, 2020In the nanoscale glass formation, the flow and deformation behavior of glass materials are quite different from those in the macroscale because the mold cavity influences the viscous flow behaviors of glass because of the size effect. The knowledge of macroglass molding process no longer applies to the fabrication of glass microparts by hot embossing ...

Hot embossing of discrete microparts
Polymer Engineering & Science, 2009AbstractThe hot embossing process has so far been developed mainly for replication of surface structures on thermoplastic substrates. Because of the lack of a through‐thickness action, fabrication of discrete microparts such as microgears is considered difficult.

Hot embossing on polymethyl methacrylate
2006 8th Electronics Packaging Technology Conference, 2006Micro hot embossing experiments were conducted on polymethyl methacrylate (PMMA) to look at the effects of holding load, temperature and time on the fidelity of line arrays representing micro channels. The results revealed that the holding temperature was a more sensitive parameter than the others due to its large effect on the polymer's viscoelastic ...

Hot embossing of microfluidic platform
International Communications in Heat and Mass Transfer, 2006Abstract Microfabrications of polymer are becoming increasingly important and considered as a low-cost alternative to the silicon or glass-based MEMS technologies. However, most of hot embossing studies were done on a thin film that may not fulfill the structure requirement of the product.

Ultrasonic Vibration Hot Embossing
International Polymer Processing, 2005Abstract Hot embossing has become a popular method for replicating precise micro-features onto large plastic plates. However, a long cycle time of the process due to conventional electric heating or hot oil heating is one of problems that confound the overall success of this technology. This study proposed a novel hot embossing method by

APPLICATION OF MICRO HOT EMBOSSING FOR MEMS STRUCTURES
International Journal of Computational Engineering Science, 2003MEMS (Micro Electro Mechanical Systems) products are being spread from laboratory to industries. But Silicon-based MEMS products are usually expensive and not suitable for low cost production. Hence, there is an emerging need in terms of cost effectiveness to transfer MEMS from silicon-based materials to other materials, such as glasses and polymers ...

Surface texturing of polytetrafluoroethylene by hot embossing
Applied Surface Science, 2010Abstract In this study, hot embossing by reusable Ni mold with features in the form of rectangular diffraction gratings of 4 μm period was successfully employed for surface texturing of polytetrafluoroethylene (PTFE) film above the glass transition temperature of PTFE amorphous phase with the aim to enhance surface hydrophobicity.

Replication of optical components by hot embossing
SPIE Proceedings, 2010Replication technology for microstructures is an essential issue for transforming expensive microstructures to cheap polymer replicas. Hot embossing has proven to be a suitable technology to fulfil the requirements of industrial applications and to fill the gap between the laboratory and the consumer market.
