This direct drive overlock serger reaches an ultra-high sewing speed up to 7000 sti/min, paired with integrated servo direct drive technology. It is engineered for mass garment factories, knitwear workshops, underwear, sportswear and apparel finishing lines, bringing tangible advantages to your production output, seam consistency and operating cost.
✅ Boost Production Capacity Significantly Compared with regular 5000–5500 sti/min overlock models, the 7000 sti/min high speed greatly raises hourly output. More pieces can be finished within the same shift, helping you meet tight order schedules and expand order handling capacity without adding extra machines or workers. It is a perfect upgrade for high-volume cutting and overedging production.
✅ Stable & Consistent Stitch Quality Even at Top Speed Many high-speed machines suffer skipped stitches, broken threads or uneven seams when running fast. This direct drive overlock adopts optimized looper, thread take-up and feeding structure. At 7000 sti/min, stitches remain uniform, tight and clean. Differential feed stays stable to avoid fabric puckering, stretching or gathering on knits, jersey, spandex and lightweight woven fabrics. Good seam quality is maintained while you chase speed.
✅ Fast Response of Direct Drive Servo The direct drive motor eliminates belt slip and transmission loss. It accelerates to 7000 sti/min rapidly and brakes instantly. No lag at start or stop. Shorten the idle time between pieces, smooth continuous workflow, and reduce wasted time for each sewing cycle. Operators can control speed precisely on demand.
✅ Lower Vibration & Lower Noise for Long-Time Operation Well-balanced internal cam and shaft design supports stable running at 7000 sti/min. Vibration is well controlled. The working environment is quieter than old belt-driven high-speed machines. Less operator fatigue during long-hour shifts, which helps sustain stable working efficiency all day long.
✅ Reliable Durability & Reduced Downtime The whole mechanism is reinforced to withstand sustained operation at 7000 sti/min. Optimized lubrication system protects moving parts from overheating and wear under continuous high-speed running. Less breakdown, fewer maintenance stops and longer service life for heavy daily production.
✅ Wide Fabric Compatibility at High Speed It handles thin tulle, knit fabrics, cotton, polyester, blended fabrics and medium-thickness stretch materials smoothly at maximum speed. Clean edge finishing for T-shirts, leggings, underwear, casual wear and home textiles. Suitable for 3-thread, 4-thread and 5-thread overlock & safety stitch jobs.
✅ Better Return on Investment Higher output per machine lifts workshop turnover. Direct drive also saves power consumption vs traditional clutch motors. Combined with fewer rejected pieces thanks to stable high-speed stitching, your unit sewing cost drops obviously.
