Product Core: Unyielding Closure for Extreme Loads

Shanghai Guangzhi Automation’s Plain Sew Heavy Duty Bag Closing System delivers military-grade stitching for 50-100kg abrasive material sacks (cement, ores, fertilizers). Engineered with triple-thread interlock technology and Hardox 500 armor, it withstands 24/7 mining/cement plant operations while achieving 120 bags/hour – 40% faster than industry standards.

Rugged Engineering Innovations

1. Triple-Thread Lock Defense

• Kevlar-Reinforced Thread: 55 lb tensile strength (ASTM D885)

• NeedleFortress? System: Tungsten-carbide needles (200K+ stitch lifespan)

2. Industrial Battlefield Readiness

• Hardox 500 Frame: 3x impact resistance vs standard steel

• IP68 Sealed Drives: Submersible-grade protection against dust/water

• Vibration Dampeners: Stabilizes stitching in high-shock environments

3. ATEX Zone 22 Combat Kit

• Explosion-proof servo motors (Ex IIB T4)

• Nitrogen purge ports for combustible dust clouds

• Grounded static-dissipation system (<10? Ω)
