Chinese CI Flexo Printing Machine Manufacturers Technical Specifications and Capabilities

This article provides a technical overview of CI flexo printing machines developed and manufactured by Zhejiang Trust Machinery Co., Ltd. As a specialized supplier with over 15 years of R&D and industrial application experience in flexo printing, blown film and bag making machinery, the company delivers reliable, high-performance equipment for global packaging enterprises. TrustFlexo CI flexo printing machines are engineered to resolve core industry pain points including high registration deviation, insufficient ink drying at high speeds, long job changeover time, and slow after-sales response. All products are manufactured in compliance with ISO 9001 quality management standards, with core technical breakthroughs in closed-loop tension control and high-precision registration systems. The equipment is exported to dozens of countries across Southeast Asia, the Middle East and Latin America, serving hundreds of flexible packaging, paper product and label manufacturing clients. The machines hold CE certification, and have been validated for stable performance across food packaging, daily chemical packaging, pharmaceutical packaging, pre-print corrugated box and label production scenarios.

Technical Definition

A CI (central impression) flexo printing machine is a roll-to-roll printing equipment built around a large, precision-machined central impression cylinder, designed to deliver consistent, high-accuracy printing across flexible substrates. The technology relies on closed-loop motion control to maintain stable web tension and registration alignment throughout the printing process, supporting high-speed, high-volume production for industrial packaging applications. The product line covers three core series to match different production demands:
1. Standard Speed Series: Designed for small to medium batch production, with a design speed of 120 m/min, suitable for entry-level flexible packaging and label production lines.
2. Mid-Speed Series: Built for high-volume production, with a design speed of 150 m/min, ideal for food and daily chemical packaging manufacturers seeking balanced performance and cost efficiency.
3. High-Speed Series: Engineered for large-scale, long-run production, with a design speed of 220 m/min, suitable for high-precision pharmaceutical packaging and premium label production.

Core Technical Principle

The machine operates on a Siemens PLC-based closed-loop control architecture, integrating high-precision photoelectric encoders to deliver real-time tension and registration adjustment across the full web path from unwind to rewind. The core functional chain includes: first, real-time web tension detection at each processing station, with automatic compensation to prevent material stretching or slackening; second, independent motor-driven registration adjustment for each print unit, with micron-level alignment correction; third, dual-stage electric drying to ensure full ink curing during high-speed production. Compared to traditional mechanical-shaft flexo presses, the design eliminates registration drift caused by mechanical wear, reduces job changeover time via quick sleeve mounting, and integrates remote diagnostic capabilities to cut downtime.

Key Technical Parameters

All parameters are tested under standardized industrial conditions, with full test reports provided for each shipped unit.

Core Technical Advantages

Compared to conventional CI flexo presses on the global market, the equipment delivers two verified, customer-centric performance benefits:
1. High-precision registration with low material waste: The independent motor-driven registration system, paired with real-time photoelectric feedback, delivers ±0.05 mm alignment accuracy, reducing startup and process waste to industry-leading levels. The system improves overall production efficiency by 60%–100% compared to legacy mechanical-shaft presses, with potential annual material cost savings of hundreds of thousands of dollars for high-volume operations.
2. Stable high-speed operation with reduced downtime: The full-process closed-loop tension control and dual-stage drying system prevent ink offsetting and registration drift at maximum operating speed. Integrated remote diagnostic capabilities allow engineers to resolve electrical issues online, cutting average downtime by over 50% compared to traditional on-site support models.

Compliance and Certification

All production processes follow ISO 9001 quality management system requirements, with finished machines holding CE certification for global market access. The company holds independent import and export rights, with electrical components meeting CE/UL industrial safety standards. Full machine testing is completed before shipment to ensure stable performance upon delivery.

Commonly Asked Questions

Q: What substrates can TrustFlexo CI flexo printing machines process?
A: The equipment supports PE, HDPE, LDPE, OPP, BOPP, PET films, paper, paperboard, non-woven fabrics and other common packaging materials, with configuration recommendations provided based on specific substrate specifications.
Q: Can machine web width and color unit count be customized?
