The OYANG Leader Machine comprises the high-speed fully automatic non-woven box bag making machine series engineered by OYANG Group to convert non-woven fabric rolls into finished 3D box bags with inline loop handles in a single continuous pass. Represented by flagship platforms including the TECH 23 and TECH 26, this machinery line operates at continuous outputs of up to 100 bags per minute and integrates a patented 90-second automatic mold change system to eliminate format changeover bottlenecks and maximize conversion OEE.

Conventional non-woven bag making lines encounter continuous bottlenecks at handle welding and gusset forming stations. When cycling at speeds above 80 bags/min, standard analog ultrasonic welders suffer from thermal frequency drift, causing either fabric burn-through or weak seam joints that fail under retail loading.
The OYANG Leader Machine eliminates joint crystallization failures by replacing manual adjustments with a closed-loop digital acoustic system synchronized directly to the line’s multi-axis servo drives:
Continuous auto-tuning generators monitor horn temperature rise and lock resonant frequency within a tight ±10 Hz window, preventing acoustic impedance mismatch at 100 bags/min.
Proportional pneumatic valves regulate horn clamping force dynamically across varying fabric thicknesses (30–120 GSM), ensuring hermetic seam welds without fiber perforation.
Precision-milled titanium sonotrodes maintain uniform energy distribution across cross-folded loop handles, consistently delivering tensile burst strengths exceeding 150 N.
By stabilizing acoustic impedance and eliminating micro-stretching along fabric feed sections, OYANG converting lines maintain scrap rates strictly below 1.5%, protecting converter raw material margins during multi-shift operations.
Engineered to match diverse commercial conversion requirements, the OYANG Leader Machine series provides distinct speed and dimension envelopes:
| Specification / Model | TECH 26 | TECH 23 | OYANG 20 | OYANG 16S |
|---|---|---|---|---|
| Production Speed | 90 – 100 bags/min | 90 – 100 bags/min | 80 – 100 bags/min | 60 – 80 bags/min |
| Auto Mold Change | Standard (90s) | Standard (90s) | Manual / Assisted | Manual |
| Max Bag Width | 540 mm | 500 mm | 480 mm | 450 mm |
| Inline Handle Attachment | Yes (Indirect Tape) | Yes (Indirect Tape) | Yes | Yes |

When running at 100 bags/min, any chassis deviation exceeding 0.02 mm creates high-frequency sympathetic vibration. Over continuous production runs, mechanical resonance deteriorates ultrasonic horns, misaligns folding knives, and destabilizes servo motors.
OYANG Digital Manufacturing Center utilizing Japanese MAZAK CNC systems for precision wallboard processing.
All structural components of the OYANG Leader Machine—including solid cast-iron wallboards, main eccentric drive shafts, and die-cutting frames—are finish-machined on Japanese MAZAK and OKUMA 5-axis CNC machining centers. Holding flatness and parallelism tolerances within ≤ 0.015 mm guarantees vibration-free operation and an extended equipment lifespan exceeding 15 years.
The TECH 26 is OYANG’s flagship automatic non-woven box bag line, engineered for high-volume packaging suppliers. It features a complete bus-control multi-servo system and an indirect tape applicator.
Engineered for agile medium-to-large conversion plants, the TECH 23 balances continuous running speed with fast dimensional recipe changeovers.
The flagship models of the OYANG Leader Machine series, including the TECH 23 and TECH 26, achieve stable production speeds of 90 to 100 bags per minute, depending on the bag dimensions and fabric GSM.
The OYANG TECH 23 and TECH 26 feature a patented automatic mold change system that completes the entire mechanical transition in just 90 seconds, compared to the 2 to 4 hours required by traditional nonwoven bag machines.
Yes, the OYANG Leader Machine is fully compatible with RPET (Recycled Polyethylene Terephthalate) nonwoven materials, allowing manufacturers to produce highly durable, 100% recyclable, and eco-friendly packaging bags.
OYANG utilizes high-end Japanese MAZAK and OKUMA CNC machining centers in its smart factory to process all core mechanical parts, ensuring a flatness tolerance of ≤ 0.015 mm for vibration-free high-speed operation.
