High-rate Manufacturing of 3D Products with Micro and Nanostructured Surfaces
Injection molding permits the manufacturing of complex three-dimensional products with micro and nanostructured surfaces in less than 30 seconds. Successful high-rate manufacturing of these surfaces depends on understanding the changes required in material selection, tool [...]
Nanopatterning planar and non-planar mold surfaces for a polymer replication
Cech J., Cheong L.Y., Kofod G., Matschuk M., Murthy S., Pranov H., Taboryski R., Technical University of Denmark, DK
We present a novel process to create nanopatterns on planar and non-planar polymer replication tools, such as metallic molds for an injection molding. Such tools with nanopatterned cavities then allow affordable mass production of nanopatterned [...]
All-In-Polymer Injection Molded Device for Single Cell Capture Using Multilevel Silicon Master Fabrication
Larsen S.T., Matteucci M., Taboryski R., Tanzi S., Technical University of Denmark, DTU Nanotech, DK
This work demonstrates a novel all-in-polymer device for single cell capture applicable for biological recordings. The chip is injection molded and comprises a “cornered” (non planar) aperture. Zanetti et al. have reported that mammalian cells [...]
Injection molded superhydrophobic surfaces
The Lotus effect is used as inspiration for the fabrication of injection molded (IM) hierarchical polymer surfaces with self-cleaning properties. IM is a widespread method for the fabrication of plastic items. Surface functionalization is traditionally [...]
Evaluation of stability for monolayer injection molding tools coating
We tested and characterized molecular coating of Aluminium and Nickel prototype molds and mold inserts for polymer replication via injection molding (IM). X-Ray photoelectron spectroscopy (XPS) data, sessile drop contact angles with multiple fluids, surface [...]
Replication of nano dimple structures by injection molding with rapid thermal control system
The present study proposes an efficient and easy mass production method for nano dimple structures by injection molding. Anodic aluminum oxide (AAO) technique is utilized to make a master with nano dimple structures, and then [...]
