High-Speed Converting Technology & Cleanroom Engineering: 16 Full-Servo Lines & Class 100,000 Environment
Technical overview of Shenghongda's 16 high-speed full-servo converting lines (Zuiko & Fameccanica), Class 100,000 GMP cleanroom, and automated CCD laser defect screening.
Engineering Summary & Manufacturing Architecture: Quanzhou Shenghongda Hygiene Products Co., Ltd. operates an 8,000+ mยฒ integrated production campus designed around Class 100,000 (ISO Class 8 equivalent) HEPA-filtered dust-free cleanrooms. Converting operations are powered by 16 full-servo high-speed converting lines engineered by Zuiko Corporation (Japan) and Fameccanica Group (Italy), capable of running up to 800 pieces per minute with synchronized electronic tension control. The facility integrates high-precision continuous ultrasonic bonding for 360ยฐ elastic waistbands, dual-drum fluff forming chambers, and gravimetric SAP dosing units maintaining +/-0.1g polymer distribution accuracy. Quality assurance is maintained in-line through multi-channel CCD visual inspection cameras and pneumatic kick-out stations that discard flawed units at full production speed without interrupting line momentum. Shenghongda produces over 1.2 billion absorbent articles annually with direct container loading facilities.
