DSGK20-DN-2S

The GK20-DN-2S series sealing sewing machine is a newly developed bag-closing machine, designed based on the proven DN-2, DS-9, and GK8 models. Built for heavy-duty industrial use, it combines robust construction with user-friendly features to deliver reliable, high-quality stitching.

Key Advantages

Closed Automatic Lubrication System: The fully enclosed automatic lubrication system ensures consistent, splash-style oil supply to moving parts, keeping the machine running smoothly with low noise and minimal wear.

Strong Sewing Performance: It features a large needle bar stroke and powerful upper/lower synchronous feeding mechanism, enabling excellent thick-seam sewing capability, uniform stitch formation, and neat, consistent seam appearance.

Durable & Low-Maintenance Build: Critical components are precision-machined from high-quality carbon alloy structural steel, heat-treated for high hardness, gloss, and dimensional accuracy. Wear-resistant steel bushings on key shafts and connecting rods further enhance abrasion resistance, ensuring high-speed, quiet operation, long service life, and easy maintenance.

Applications

Ideal for sewing various woven bags in industries including paper bag manufacturing, cement plants, chemical factories, and other industrial packaging facilities.
