Adhering strictly to ISO 9001 and CE standards, we achieve breakthroughs in ±0.05mm registration accuracy and full-process closed-loop tension control. Our products are exported to dozens of countries, serving clients in food packaging, personal care, and pharmaceutical sectors, and are recognized as reliable solutions with ISO and CE certifications.
Plastic film flexographic printing presses are roll-to-roll systems using flexible relief plates, optimized for high-speed, high-precision printing on plastic substrates. Based on servo-driven closed-loop control technology, these machines ensure stable, consistent printing across diverse production scenarios. As a core solution in the flexible packaging machinery sector, they are indispensable for efficient, high-quality packaging production.
Main Categories
1. High-Speed Series: Designed for large-batch production, with a design speed of 220 m/min, ideal for food and personal care packaging, featuring dual-stage electric drying and anti-clogging anilox rollers.
2. Standard Precision Series: Balances speed and flexibility, with a design speed of 150 m/min, suitable for multi-variety small-batch production, equipped with intelligent centralized control and quick-change sleeve structure.
3. Custom Wide-Format Series: Supports web widths up to 1600mm, tailored for industrial packaging, offering fully customizable color units and configurations.
Design Philosophy: Our products prioritize precision, reliability, and deep customization, following full-life-cycle reliability standards to deliver stable, cost-effective solutions for harsh industrial scenarios.
The core working principle of our presses is based on Siemens PLC-controlled servo-driven closed-loop systems. The operational link includes:
1. Unwind Stage: Tension sensors detect material slack or stretch, sending real-time data to the PLC for automatic compensation to prevent registration drift.
2. Printing Stage: Independent servo motors and precision ball screws drive horizontal and vertical registration, with photoelectric encoders providing real-time feedback to maintain ±0.05mm accuracy.
3. Drying Stage: A dual-stage electric drying system uses high-temperature airflow to ensure thorough ink curing before the next color station, eliminating ink offset.
Core Architecture & Innovative Design
- Siemens PLC Control Module: Centralizes parameter management, stores job recipes, and tracks historical data to simplify changeovers.
- Closed-Loop Tension Control Module: Provides automatic detection and compensation from unwind to rewind, ensuring stability across diverse substrates.
Compared to traditional mechanical-shaft presses, our servo-driven system reduces registration deviation by 90% and cuts changeover time by 60%, addressing long-standing industry pain points.
All parameters are tested strictly per ISO standards, with clear test conditions and tolerance controls. We provide full parameter test reports for each batch, supporting third-party inspection.
