High Speed Spot UV Machine

Advantages
The UV coating machine supports both spot UV and full-page UV coating, enhancing the visual vibrancy and tactile texture of printed paperboard.
Compared with screen printing equipment, the spot UV function of this machine drastically cuts varnish consumption and lowers your raw material costs.
Traditionally, most printed cartons adopt film lamination. Lamination brings two obvious drawbacks:
First, plastic film is unfriendly to environmental protection and recycling requirements.
Second, the laminated film surface has poor adhesion. Without a plasma treatment device installed on the folder gluer, carton gluing failure frequently occurs.
Our spot UV machine can realize full-page UV coating while reserving glue-free zones. Therefore, no extra plasma equipment is required on your folder gluer, saving additional procurement and maintenance costs.

Features
High-precision spot UV registration: registration accuracy reaches ±0.2 mm.
Large-diameter transfer rollers effectively reduce paper curling, realizing stable coating processing for thick paper stock.
Dual-pressure roller design lowers the surface tension of UV varnish, eliminates orange peel defects and achieves superior surface gloss.
Heavy-duty cast iron frame structure guarantees vibration-free stable operation under high-speed running conditions.
High-speed feeding system equipped with front lay guides, grippers and cam transmission mechanism, delivering reliable sheet positioning at high production speeds.
Full gripper bar transmission throughout the whole workflow, from coating station to final stacking section.
Equipped with IR + hot air + UV drying system. LED UV dryer is available as an optional upgrade for LED UV varnish application
