OYANG Leader Machine: Industrial Precision in Non Woven Box Bag Automation
Designed to resolve structural vibration and sealing bottlenecks in 3D pouch conversion, the OYANG leader machine family—led by the flagship TECH 23 and TECH 26 platforms—delivers high-speed output at 90–100 bags/min. As the industry benchmark for any high-specification leader non woven bag making machine, this series integrates auto-frequency-tracking ultrasonic bonding, real-time closed-loop web tension compensation, and an automated mold-change sequence executed in under 90 seconds across 40–120 gsm virgin and recycled nonwoven substrates.
Field Failure Diagnostics: Overcoming Mechanical Limits of Fabric Box Bag Lines
Standard commercial market converters running conventional gear-linkage machinery routinely hit operational limits once line speed exceeds 65 bags/min. In high-throughput 3D shopping bag conversion, three primary mechanical bottlenecks degrade overall equipment effectiveness (OEE):
1. Resonant Ultrasonic Failure
Fixed-frequency ultrasonic transducers drift thermally during continuous 100 bag/min operation. A ±200 Hz frequency deviation causes amplitude dampening, leading to seal delamination along the bag gussets or pinholes on thin 45 gsm nonwoven layers.
2. Chassis Torsional Deflection
Welded square-tube or profile-iron frames lack dynamic damping. Operating multi-link folding mechanisms at 1.6 Hz induces harmonic vibration across cantilevered forming jaws, creating bottom-crease alignment errors exceeding ±2.5 mm.
3. Handle Weld Shear Stress
Inaccurate indexing of loop handles during pneumatic transfer causes uneven weld penetrations. The resulting handle attachments fail dynamic tensile pull tests below 15 kg, failing standard retail load ratings.
Engineering a truly reliable leader box bag machine requires decoupling kinematic transmission lines via distributed electronic line-shafting (ELS) and anchoring all reciprocating tooling into high-mass, CNC-milled wall plates.
Engineering Benchmarks: The OYANG LEADER Platform Architecture

OYANG’s TECH series redefines nonwoven bag automation by integrating multi-axis servo synchronization across web unrolling, bottom gusseting, side edge folding, ultrasonic welding, and loop handle integration. Utilizing Japanese Yaskawa motion processors connected over high-speed bus architectures, each kinematic node dynamically adjusts its position profile to preserve roll tension within ±0.8 N during continuous cycles.
Comparative Engineering Specifications: TECH Platform Models
The following matrix illustrates performance metrics of the OYANG leader machinery lineup deployed for industrial box-bag manufacturing:
| Model Configuration | Operational Speed | Bag Width / Bottom Depth | Fabric Caliper | Mold Changeover Time |
|---|---|---|---|---|
| TECH 26 Leader Line | 90–100 bags/min | 200–500 mm / 80–220 mm | 40–120 gsm (PP/Spunbond/RPET) | Full Auto ≤ 90 seconds |
| TECH 23 Leader Series | 80–100 bags/min | 230–480 mm / 70–200 mm | 45–110 gsm (Laminated/Raw) | Manual Assist ≤ 12 minutes |
| OYANG 20 Platform | 80–100 bags/min | 200–450 mm / 80–200 mm | 50–120 gsm Nonwoven | Standard Mechanical Change |
Manufacturing Integrity: CNC Machining Centers Guaranteeing Lifecycle Alignment
Long-term dynamic precision is a direct consequence of frame machining tolerance. At OYANG’s 130,000 m² advanced equipment production hub, all main structural wall panels and transverse mounting blocks are processed in-house on Japanese OKUMA and MAZAK five-axis horizontal machining lines.
- Strict Planar Tolerance: Plate surfaces are milled to a continuous flatness tolerance of ≤ 0.015 mm, eliminating bearing angular misalignment under severe mechanical stresses.
- Vibration Suppression: Integrated high-rigidity ductile iron wall castings absorb high-frequency oscillation produced by 20 kHz ultrasonic sonotrodes.
- Standardized Component Interface: Laser-interferometer-guided alignment ensures seamless drop-in placement for automated tool changes.

Frequently Asked Questions (FAQ)
What sets the OYANG leader machine apart from third-party regional assemblers?
Unlike regional manufacturers that utilize welded channel-iron bases and open-loop pulse cards, the OYANG leader series is built on a 130,000 m² campus with OKUMA/MAZAK CNC-machined solid wall plates (≤ 0.015mm tolerance). This enables dynamic multi-axis bus-servo control that guarantees continuous production at 90–100 bags/min without structural deflection.
How does the leader non woven bag making machine solve seal failures on thin fabric?
The system employs continuous automatic-frequency-tracking 20kHz ultrasonic generators coupled with proportional pneumatic pressure valves. By constantly matching sonic resonance to web thickness, it prevents material burn-through on 40–45 gsm nonwoven layers while maintaining continuous weld integrity exceeding 15 kg pull strength.
What is the changeover duration on a leader box bag machine when altering box bag sizes?
On the flagship TECH 26, mold adjustments are motorized and fully automated via the touchscreen HMI, completing full dimensional size transitions in under 90 seconds. On mechanical-assist models like the TECH 23, quick-clamp plates and calibrated scale dials reduce the changeover duration to under 12 minutes.
Can OYANG leader machines process laminated and recycled nonwoven rolls?
Yes. The closed-loop active web feeding station automatically accommodates BOPP laminated nonwoven fabric, virgin PP spunbond, and post-consumer recycled RPET materials ranging from 40 to 120 gsm without requiring mechanical roller reconfiguration.
