Top Chinese CI Flexo Printing Machine Supplier Zhejiang Trust Machinerys Precision Solutions

This technical article provides a standardized breakdown of Central Impression (CI) flexographic printing presses developed by Zhejiang Trust Machinery Co., Ltd. With 15 years of expertise in flexographic printing, blown film, and bag making machinery, we are a leading global supplier dedicated to advancing industry technology. Our CI flexo presses are engineered for medium-to-large flexible packaging enterprises and high-precision sectors like food and pharmaceuticals, solving core industry pain points including registration drift, ink clogging, and slow production changeovers. Strictly adhering to ISO 9001 and CE standards, our presses achieve a breakthrough in ±0.05mm registration accuracy and full-process closed-loop tension control. Exported to dozens of countries worldwide, our certified solutions are validated in food packaging, pharmaceutical labeling, corrugated pre-printing, and paper product manufacturing.

Technical Definition

Central Impression (CI) flexographic printing machines are high-speed rotary printing systems that use a large central cylinder to ensure consistent pressure and registration across multiple printing units, enabling high-volume, high-quality packaging printing. Built on servo-driven closed-loop control technology, they are essential for efficient, precise packaging production in the flexible packaging industry.

Main Categories: High-Speed CI Series (design speed 220 m/min, ideal for large-batch orders), Standard CI Series (150 m/min, suitable for multi-variety production), Entry-Level CI Series (120 m/min, designed for upgrading small-scale enterprises). Customized configurations are available for special scenarios.

Design Philosophy: Our CI flexo presses are designed with precision, reliability, and customization at their core, adhering to full-life-cycle reliability standards to deliver stable, cost-effective solutions for industrial environments.

Technical Principles

Our CI flexo presses operate on servo-driven closed-loop registration control, with a complete workflow: 1. Automatic tension detection and compensation from unwind to rewind prevents material stretching or slackening; 2. Independent servo motors drive each printing unit, with real-time feedback from photoelectric encoders; 3. A Siemens PLC centrally synchronizes all units to maintain consistent registration.

Core Innovative Architecture: Siemens PLC Control Module integrates tension and registration control, stores job recipes, and streamlines production changeovers; Closed-Chamber Doctor Blade System features CNC-machined alloy chambers with anti-stick coating to eliminate ink leakage and improve workshop conditions.

Comparison with Traditional Solutions: Unlike traditional mechanical-shaft-driven presses (±0.2mm registration accuracy), our presses achieve ±0.05mm accuracy; traditional open doctor blade systems leak ink, while our closed system prevents leakage; traditional plate changeover takes hours, our quick-change sleeve structure cuts time by 70%.
