Supplier's note

  1. Key Technical Breakthroughs:

    • Double Needle System: Enables reinforced double chain stitches, reducing seam failure by 40% compared to single-needle machines.
    • Automatic Trimmer: Cuts threads 20% faster than manual trimmers, minimizing downtime.
    • Digital Control Panel: Offers ±5% precision in stitch adjustments, ensuring consistent quality across batches.

  2. Optimal Version Selection:

    • Base Model: Ideal for small workshops or occasional use (e.g., tailoring shops). Its manual feed and basic stitch types suit lightweight fabrics.
    • Advanced Model: Best for mid-sized garment factories requiring versatility (e.g., 5 stitch types for varied materials like cotton and synthetic blends).
    • Pro Model: Designed for high-volume production lines (e.g., denim or leather goods). The 6,500 RPM speed and 8,000-hour durability meet industrial-scale demands.

With the Pro Model’s triple-certified chemical resistance, operators can safely handle abrasive materials like PVC without compromising stitch integrity. Pair its fully automatic tension control with the double needle to achieve seamless, fray-free edges on even the thickest fabrics.
