YBW21300 Type Two-color Printing & UV Coating Line
For 1250mm wide PVC/PVC foam board or door or panels
(paint color has changed into grey+blue color)
Part 1: Performance and Application
1. It is used to printing one-color or two-colors designs and coating UV lacquer on the surface of PVC hollow doors or PVC panels or PVC boards;
2. It also can coating UV lacquer on the surface of PVC marble sheets and PVC foam boards to get matt effect, shine and high gloss effect like mirror.
3. After UV coating, it can laminate protective film directly to protect finished surfaces without any attrition in transportation.
4. Total line needs 42m length and 4.5m width space.
(the decorated panels, door, marble sheets by high gloss and matt effect)
