Engraving machines
Adopts roller engraving machines from Toshiba
Uses films, such as lenticular/prism sheets for roller engraving. The copperized or electroless nickel-plated rollers can be engraved with the nanometer mirror surface, circular, or spiral groove structure. The engraved structure can be chrome-plated for protection.

Micro structure roller machining method
With the roll-to-roll production technology, the optical film is formed by the optical-class UV resin engraved with a functional micro structure. It is imprinted by the Roll to Roll process and UV curing technology. The mold surface must be a structured processed (such as V-grooving, Pyramid Array, and Lenticular). Its key process includes the continuous transfer, where the precision engraving machine engraves the roller with the micro structure through the Roll to Roll process and UV resin coating technology for the micro structure.
