Features

Registration Accuracy Fully servo driven and equipped with advanced online monitoring, the flexo printing press ensures registration accuracy within ±0.15 mm in both cross and machine directions. Even at high speeds or sudden shifts, precision remains stable, minimizing waste and delivering flawless alignment for premium packaging and label applications.

Web Substrate Expertise Engineered for stable handling of 550–850 mm materials, especially PP woven fabric and PE films with low tension. Equipped with sensitive floating rollers and tension control, it overcomes common issues of stretching and misalignment, ensuring continuous high-speed, non-stop operation.

Durable Imported Components Core systems use top-tier international brands: chamber doctor blade technology from Denmark reduces solvent evaporation; German web guiding ensures zero deviation; Japanese servo motors deliver precise positioning. With over 80% of critical components imported, the press provides exceptional reliability, long-term stability, and higher ROI through reduced downtime.

Double-Sided Printing Featuring an innovative 4+4 CI (Central Impression) press design, the machine prints four colors on the front and four on the back simultaneously. This eliminates material flipping and secondary web runs, completing both sides in a single pass. The result is significant time and labor savings, perfectly suited for woven bags, shopping bags, and industrial packaging in high-volume production.

Intelligent Temperature Control The central impression drum features a dual-layer hollow design with PID smart temperature regulation, maintaining surface variation within ±1 °C. This prevents substrate distortion and uneven ink curing, guaranteeing consistent color stability across long production runs.
