Details:
Our nanoinjection molding technology can achieve a pattern structure of size smaller than 20 microns and is suitable for mass production. Nanoinjection molding technology combines elements of nanoimprinting with injection molding, to create three-dimensional (3D) free-form plastic products, with a micro and nanometer-scaled patterned surface.
Nanoinjection molding allows the creation of micro and nanometer-scale structures of resolutions as high as 0.5 micron to be molded directly. As a result, additional surface optical and mechanical functionalities can be added to the plastic molded products, for lab-on-a-chip and optical components applications.
The pivotal element to nanoinjection molding is the mold inserts. We use lithography and electroforming technology to create nanometer-scale patterned inserts. These sub-micron high–resolution inserts are made of hybrid nickel-steel and nickel shim. The polymer material used in nanoinjection molding are PC, PMMA COC/COP, PS or ABS, depending on the application.
Winovus is a pioneer leader in nanoinjection molding. Our state-of-the-art molding facilities are equipped with automated handling robotics, complete with in-situ and ex-situ inspection and quality control. Nanoinjection molding enables new product innovation in the consumer wearable and biomedical sector. It can value adds an existing product by imparting surface functionalities.
