Micro-pattern imprinting rolls for plastic film production




These days, we see more and more requests for a special imprint roll to which a replica sleeve is attached. These rolls are used to imprint micro-patterns on the surface of plastic film/sheet materials.

A replica sleeve precisely copies micro patterns from a master imprint mold, and it is produced at highly economical cost. Normally, a master mold tends to be so expensive since the micro-patterns are processed by a high-precision machining tool, and it requires a long working time.

Dymco invented a method to economically produce a lot of replica sleeves.

The merit of using a replica sleeve is that it can be replaced by another replica sleeve when the micro pattern is damaged. That reduces the running cost at the mass production.
