This technical article provides a comprehensive breakdown of stack-type flexographic printing presses developed by Zhejiang Trust Machinery Co., Ltd. As a leading supplier with over 15 years of expertise in flexo, blown film, and bag making machinery, we focus on driving industry technological advancement. Our stack-type presses are tailored for medium-to-large flexible packaging enterprises and high-precision sectors like food, daily chemicals, pharmaceuticals, and label printing, solving core industry pain points including registration deviations at high speeds, incomplete ink drying, and inefficient production changeovers. Built with Siemens technology and following international flexographic standards, our presses achieve breakthroughs in full-process closed-loop tension control and intelligent centralized control, with products exported to dozens of countries and validated across substrates like plastic films, paper, and non-woven fabrics.
Stack-type flexographic printing presses are multi-color printing systems that use vertically stacked independent printing units to achieve high-precision registration on diverse substrates, based on advanced flexographic technology, enabling efficient, high-quality printing for flexible packaging applications. As a core solution in the flexible packaging industry, these presses are essential for meeting high-volume, high-quality printing demands across multiple sectors.
To meet diverse industry needs, our stack-type presses cover four main series with customizable options: 1. Full Servo Series (e.g., TF-FS02/04/10-1000 1200): High-precision, high-speed series for medium-to-large enterprises, featuring 260 m/min design speed and ±0.05mm registration accuracy.
2. Semi Servo Series (e.g., TF-SS02/06/12-1000 1200): Cost-effective balance series for precision and budget needs, with 220 m/min design speed.
3. Gear-Driven Series (e.g., TF-G04/08/10-1000 1200): Economical series for small-batch production, with 120 m/min design speed.
4. Synchronous Belt Driven Series (e.g., TF-B02/04/10-1000 1200): Stable series for reliability-focused scenarios, with 150 m/min design speed.
Our presses are designed with precision, reliability, customization, and customer-centricity at their core, adhering to full-life-cycle reliability standards to deliver stable, low-maintenance, cost-effective solutions for industrial scenarios.
The core working principle of our stack-type presses is based on flexible relief printing, integrated with servo drive and closed-loop control systems. The full operational flow includes: 1. Unwind Stage: Automatic tension detection and compensation ensure stable material feeding.
2. Printing Units: Independent international-brand servo motors drive plate and impression cylinders, with closed-chamber doctor blade systems enabling uniform ink transfer from ceramic anilox rollers to photopolymer plates.
3. Drying Stage: Two-stage electric drying systems with main oven and inter-color configurations ensure thorough ink drying at high speeds.
4. Rewind Stage: Closed-loop tension control ensures neat rewinding and minimizes waste.
Our innovative modular architecture enhances performance and adaptability: 1. Full-Process Closed-Loop Tension Control: Eliminates registration deviations caused by material stretching or slackening during high-speed production.
2. Intelligent Centralized Control System: Large touchscreen manages parameters, stores job recipes, and tracks historical data to simplify production changeovers.
3. Two-Stage Electric Drying System: High-temperature, high-velocity airflow prevents ink offsetting or buildup.
Compared to traditional flexo presses, our solutions address long-standing industry pain points: 1. Traditional presses often suffer registration deviations at high speeds; our closed-loop tension control maintains ±0.05mm accuracy even at maximum speed.
2. Incomplete ink drying leads to product defects; our two-stage drying system ensures thorough drying during high-speed production.
