Recently, Leejajn, a renowned motor supplier based in Chongqing, China, has unveiled its latest product—the Junmotor.—a professional-grade precision motor engineered exclusively for flexible packaging roll equipment. Embodying the slogan “steady for big rolls, precise for small rolls,” the Junmotor tackles the industry’s core challenges: unstable tension control, inefficient speed adaptation, and high energy consumption during roll-to-roll production.
Precision Engineered for Roll-to-Roll Processes
Flexible packaging operations rely on seamless transitions of material rolls from large diameters (over 1 meter) to small (under 10 centimeters), a process plagued by uneven tension fluctuations and roller speed mismatches. Traditional motors often fail to maintain consistent tension across unwind and rewind rollers, leading to material wrinkles, misalignment during printing/laminating, or even breakage. The Junmotor integrates high-precision encoders and adaptive control algorithms to dynamically adjust speed in real-time, ensuring:
• Stable tension on large rolls during high-speed unwinding,
• Micro-level precision on small rolls to prevent slippage or over-stretching on guide rollers and nip rollers.
High-Speed Performance Meets Energy Efficiency
Designed for demanding production lines, the Junmotor delivers 8,000 RPM or higher speeds without compromising control—a 30% speed upgrade over standard motors. This enables faster throughput in processes like flexographic printing and film lamination while maintaining material integrity. Coupled with permanent magnet synchronous technology, it reduces energy consumption by up to 10%, cutting annual electricity costs for a typical factory by tens of thousands of dollars.
Industry Validation and Global Reach
“After installing Junmotor, our waste rate dropped by 25% due to precise tension control on both large and small rolls,” reports a technical manager at a major packaging firm. “The motor’s ability to sync with our roller systems flawlessly has been a game-changer.”With CE certification and a focus on flexible packaging machinery manufacturers (e.g., for food packaging, pharmaceutical films, and industrial bags), Leejajn plans to expand Junmotor’s availability in Europe, Southeast Asia, and North America by 2025, targeting partnerships with OEMs and end-users alike.
Junmotor by Leejajn isn’t just a motor—it’s a precision-engineered solution that turns the complexity of roll-based production into a competitive advantage. Steady for big rolls. Precise for small rolls. Professional for every process.
