Key Features
1. High-Precision Linear Motor Technology
The compact printhead carriage uses a linear motor to improve printing accuracy and motion smoothness. The drive system offers low wear, low noise, and high efficiency, supporting stable operation over extended periods.
2. Integrated Development and Manufacturing by Bihong
Both the oval screen printing machine and the digital printer are independently developed and manufactured by Bihong, optimizing compatibility and coordination between the two machines.
3. Multiple Printhead Options
The system supports a wide range of printheads, from industrial-grade Ricoh G5, Starfire, and Kyocera printheads to high-precision, high-resolution Epson printheads, accommodating different print quality and production requirements.
4. Intelligent Printhead Cleaning and Ink Purging System
Automatic wiping and pressure purging simplify printhead cleaning, help prevent nozzle clogging, and maintain consistent print quality.
5. Advanced External Ink Circulation System
The intelligent ink supply system uses external circulation to reduce the risk of ink solidification and ensure stable operation over extended periods.
6. High-Sensitivity Anti-Collision Sensors
The printhead carriage is equipped with high-sensitivity anti-collision sensors to protect the printheads against unexpected impacts during printing.
7. High-Quality Imported Ink
Carefully selected imported ink ensures smooth, stable ink jetting and consistent print quality.
