An OYANG bag making machine comprises the industrial, multi-axis servo converting machinery engineered by OYANG Group to transform continuous substrate webs—including kraft paper, PP non-woven fabric, and high-barrier flexible films—into commercial bags. Covering three primary configurations including roll-fed square bottom paper bag lines (up to 220 bags/min with 2-minute digital changeover), fully automatic ultrasonic 3D box bag machines (90–100 bags/min with 90-second motorized mold swaps), and multi-format flexible pouch systems (up to 240 strokes/min), OYANG equipment utilizes closed-loop EtherCAT servo tension coordination and stress-relieved HT250 cast-iron frames machined to ≤ 0.015 mm tolerances on Japanese MAZAK and OKUMA 5-axis CNC centers to ensure continuous line stability.
The Engineering Behind High-Speed Web Tension Control
In continuous web converting, fluctuations in web tension are the primary source of registration drift, fold misalignment, and web rupture. Whether processing lightweight 60 GSM kraft paper or structural 100 GSM non-woven fabrics, OYANG converting platforms employ dynamic closed-loop servo tension regulation:
Where T represents instantaneous web tension, T0 is the initial calibrated static tension, A is the substrate cross-sectional area, E is the Young’s Modulus of the web material, v0 is the nominal line take-up speed, and Δv is the micro-velocity differential across adjacent servo draw rollers. Governed by high-speed EtherCAT motion controllers, OYANG machines dynamically regulate Δv within sub-millisecond cycles, restricting web tension drift to within ±1% during full acceleration to 220 m/min.

Why In-House Precision Machining Protects Converter ROI
Long-term converting accuracy depends directly upon the dynamic rigidity of the machine chassis. Operating continuously at speeds up to 220 cuts per minute generates high-frequency mechanical shock waves. OYANG eliminates structural distortion by managing all structural fabrication within our 130,000 m² manufacturing complex:

All chassis wall panels, eccentric drive shafts, and cutter blocks are cast from stress-relieved HT250 iron and machined on Japanese MAZAK and OKUMA 5-axis CNC machining centers. Holding cumulative datum tolerances to ≤ 0.015 mm eliminates gear backlash, prevents ultrasonic horn thermal misalignment, and guarantees machine operational longevity exceeding 15 years.

Frequently Asked Questions (FAQ)
What types of bags can OYANG machines produce?
OYANG bag making machines produce square-bottom SOS paper bags with flat or twisted rope handles, flat-and-satchel bakery bags, 3D non-woven box tote bags with inline handles, D-cut merchandise pouches, and flexible barrier pouches (stand-up, zipper, and 8-side seal flat bottom bags).
How long does a size changeover take on an OYANG paper bag machine?
On automated models like the OYANG TECH-18, a bag size format changeover takes approximately 2 minutes via automated servo adjustments recalled through the intelligent HMI recipe management screen.
What precision standards are maintained during OYANG machine manufacturing?
All core structural wallboards, bearing seats, and main shafts are machined on Japanese MAZAK and OKUMA 5-axis CNC machining centers to geometric tolerances of ≤ 0.015 mm, eliminating harmonic vibration at operational speeds up to 220 bags/min.
Are OYANG bag making machines certified for global export?
Yes, all OYANG converting lines hold verified SGS CE certifications, conforming to European machinery safety directives, alongside ISO9001 quality management and CNAS national high-tech laboratory accreditation.
