In the fiercely competitive label and packaging printing industry, traditional printing enterprises are facing severe pain points such as shrinking profit margins, high material waste, time-consuming multi-color high-precision registration, and the inability to meet diversified, short-cycle reorder demands. How to achieve high speed, cross-material compatibility, and fully automated operations on a single machine is the key to enhancing your core competitiveness. As a leading manufacturer of QianRun Flexo Printing Machines, we deeply understand these pain points and have launched the brand-new QianRun S6-370 inline flexo press to provide you with a comprehensive label printing solution.
Product Advantages & Revolutionary Solutions
● Ultra-High Stability & Precision
Traditional mechanical gear drives often result in poor registration due to wear and tear, leading to significant waste. The QianRun S6-370 utilizes an advanced shaftless drive driven by independent dual servo motors, supporting online automatic pre-registration and over-registration. Its registration accuracy reaches an astonishing $\le \pm \text{0.10mm}$, with extremely easy adjustment. This eliminates material loss caused by mechanical errors from the source, significantly lowering your long-term comprehensive operational costs associated with the competitive flexo printing machine price.
● Zero Ink-Bar & Petal-Shaped Plate Cylinder
Addressing the common "ink bar" pain point in fine label printing, this equipment adopts an innovative petal-shaped plate cylinder structure. Plate changing is fast and efficient without the need for cumbersome large adjustments, fundamentally eliminating the impact of ink bars on print quality. This ensures that every high-end cosmetic label or electronic label presents a flawless visual effect via our advanced inline flexo printing machine.
● Multi-Substrate Adaptation with Water Chiller
Traditional presses often cause thermal deformation when dealing with unsupported films (such as PET, OPP, PP). The QianRun S6-370 is equipped with a large size anvil roller paired with a water chiller, offering exceptional adaptability to unsupported film materials. It easily handles multi-layer high-quality printing on self-adhesive labels, films, thin paper, and up to 350gsm paperboard, perfectly covering full-scene applications from cigarette packs to cell phone battery stickers using premium inline flexo printing machines.
● Intelligent Non-Stop Production & One-Key Retrieval
Time is money. The system can be configured with an optional intelligent non-stop rewinding and unwinding system that supports automatic paper splicing. Combined with a full-visual automatic overprinting system, it not only realizes automatic registration but also saves order data. This means that when the next identical order arrives, you can achieve one-button data retrieval for instant printing, reducing traditional job setup times by over 80% and drastically boosting the efficiency of an Inline Flexo Printing Machine setup.
