Gachn Valve Sack Making Machine: High-Speed & Low-Waste for Mass Production

Core Industry Pain Point: Traditional Bag-Making Bottlenecks Restrict Capacity Upgrading

In powder industries like cement, chemicals and grain, demand for valve sacks keeps growing. Traditional bag-making machines suffer from low speed, high scrap rate, slow size changeover and high maintenance cost. Standard machines run at only 60-80 pcs/min with startup scrap rate over 3%; unstable bottom/valve sealing causes powder leakage; size change takes over 30 minutes manually; frequent wear parts replacement raises annual cost, making mass production hard to sustain.

Core Solution: FK008-II Full-Servo Valve Sack Making Machine

Gachn Group's FK008-II Valve Sack Making Machine adopts full-servo control, patented triangular bag-opening and bottom-patch vacuum transfer tech, specially built for mass production of PP woven block-bottom valve sacks, solving pain points in efficiency, waste and stability.

Key Performance Advantages

High-Speed Stable Production: Stable speed at 110-120 pcs/min, 50% higher than traditional machines; fits 350-600mm bag width & 450-910mm bag length, daily capacity over 150,000 pcs.

Ultra-Low Waste for Cost Saving: Startup scrap rate under 0.5%; unique bottom-patch process supports uneven-edge materials, saving over 400,000 yuan/year on materials; constant-temperature heat sealing ensures nearly zero bottom breakage & powder leakage.

Fast Size Changeover: Modular molds and graphic HMI enable size change in 5 minutes for flexible multi-spec production.

Minimal Maintenance & Durability: No wear parts in bag-opening mechanism; Schneider servo system ensures MTBF over 6000 hours; remote diagnosis cuts annual maintenance cost by over 60%.

Smart Quality Inspection: Optional vision system auto-detects defects and rejects waste, finished product pass rate ≥99.5%, greatly reducing manual inspection cost.

Customer Validation: Proven for Mass Production

A leading domestic packaging enterprise upgraded with FK008-II, boosting bag-making capacity by 55%, saving over 800,000 yuan/year in total cost, and raising pass rate from 95% to 99.7%. It has become a core line for cement & chemical powder packaging. The model has been exported to over 20 countries in Southeast Asia, Central Asia and Africa, serving 100+ mass-production bag factories.
