Technical Dossier: 3x German Hanwei High-Speed Diaper Converting Lines
Bottom Line Up Front (BLUF): Baron Hygiene operates 3 dedicated German Hanwei full-servo baby diaper converting lines running at continuous speeds of 800 to 1,000 pcs/min. Utilizing German Siemens synchronous servo drive controllers, proprietary dual-drum vacuum SAP forming chambers, and 100% inline optical defect detection, these machines represent the peak of global hygiene converting automation.
German Hanwei Full-Servo Converting Infrastructure
The 3 German Hanwei lines represent our most technologically advanced asset for international private-label manufacturing. Featuring full electronic servo gearboxes with independent axis drives, each raw material web (hot-air nonwoven, fluff pulp, SAP, breathable PE film, and Lycra elastic) is stabilized through closed-loop tension controllers that eliminate tensile drift.
- Continuous Running Speed: 800 to 1,000 pieces per minute (stable operational rate).
- Dual-Drum Vacuum Forming: Uniform distribution of SAP particles with zero clumping.
- Zero-Stop Automatic Splicing: Splicing nonwoven rolls at 800 m/min without machine deceleration.
- Ultrasonic Side Seam Bonding: High-frequency sound welding creating soft, tear-away side seams without stiff thermal crusts.
