Скачать или смотреть Ultrasonic Top Hemming in Action – Urea Bag Production with QF-QTFQ-750

This video captures the real production of white urea bags using our QF-QTFQ-750 Multi-Function PP Woven Bag Machine at a customer factory.

Watch how our ultrasonic top hemming system ensures tight, clean, and durable bag mouths. The machine handles the full process of cutting, liner insertion, bottom sewing, and top hemming in one seamless workflow.

✅ Why This Machine Stands Out:
• Modular 4-in-1 design – each function can run independently or together
• Ultrasonic top hemming – perfect for powder and food-grade bags
• Servo-controlled precision – ±1.5mm accuracy for consistent results
• Cold/hot cutting switch – clean edges with or without lamination
• Dual bottom sewing modes – support for PE inner liners
• Auto deviation correction, remote monitoring, and automatic bag stacking

⚙️ Production Speeds:
• 15–20 bags/min (full process: liner + top hemming)
• 20–27 bags/min (top hemming only)
• 22–35 bags/min (liner only)
• 40–50 bags/min (cutting & sewing only)

🛍️ Applications:
Perfect for urea, fertilizer, animal feed, flour, sugar, and industrial powder bags. Ensures strong seams, sealed liners, and durable bag edges.
