Description

TECHNICAL FIELD

[0001] The utility model relates to a hollow plate roller copper plating hanger. BACKGROUND

[0002] The plate roller is a tool for making plates, and its roller surface is usually plated with a copper layer and engraved with patterns by the engraving process of a gravure electronic engraver, and then plated with chromium again to increase its durability. After completion of the manufacturing and delivery to the printing factory, they are often used for printing work in related fields such as plastic packaging.
