Hebei Jingze Textile Co., Ltd. — a leading sewing thread producer in China — has set a new benchmark for precision winding by integrating SSM’s NEO-BD precision assembly winder into its operations. With this step, the company achieved a 100 % speed increase, higher yarn quality, and greater process reliability — all while meeting rising customer demands for consistency and performance.
Overcoming the limits of conventional winding
Before the upgrade, Hebei Jingze struggled with operational bottlenecks typical of high-volume production:
- Winding speeds capped at around 500 m/min, limiting throughput.
- Weight variation in yarn packages, causing inefficiencies in downstream twisting.
- Quality issues such as split yarn and braided yarn under high tension.
- The need to scale up output without increasing waste or labor costs.
The company recognized that its existing setup could no longer support its growth trajectory.
Smart technology delivers precision and power
To address these challenges, Hebei Jingze adopted the NEO-BD precision assembly winder — a solution designed for both speed and control. Key technology features include:
- preciforce back-pressure regulation ensuring perfectly uniform package density.
- digitens online tension monitoring for real-time control and stable yarn tension.
- High-accuracy length and weight measurement (±0.3 %) for consistent packages.
- Maximum winding speed of up to 1 600 m/min without compromising yarn integrity.
The company installed five NEO-BD machines with 72 spindles each, enabling a major leap in productivity.
Measurable results that speak for themselves
| Metric | before | after | improvement |
|---|---|---|---|
| Winding speed | ~ 500 m/min | ~ 1 000 m/min | + 100 % |
| Yarn quality | Baseline | Superior | + 5–10 % |
| Package weight variation | 25–30 g | < 10 g | − 65 % |
| Twisting efficiency | Reference | Optimized | + 5 % |
| Defects | Frequent | Minimal | Significant reduction |
Additional benefits included:
- Longer production runs with heavier, more uniform packages.
- Elimination of yarn defects, leading to higher end-product quality.
- Flexible package weights (1.25 kg, 1.40 kg, 1.667 kg) to match production needs.
Encouraged by these results, the company has already expanded its investment in NEO-BD winding systems.
