OYANG Machinery China: Redefining High-Speed Conversion for Global Converters
For decades, high-speed bag manufacturing and rotogravure technologies were dominated by European equipment manufacturers. Today, OYANG Machinery China has closed this technological gap through continuous multi-axis servo development, dynamic tension control innovations, and rigorous CNC manufacturing standards.
By merging China’s complete industrial supply chain with advanced digital automation, OYANG Group delivers industrial converters worldwide with European-tier operational reliability, accelerated changeover speeds, and competitive lifecycle payback periods.
The Science of Extrusion Lamination: Polymer Adhesion Physics
A core manufacturing competency within OYANG Group’s converting line portfolio is high-speed extrusion coating, engineered to apply hermetic barrier polymer films onto non-woven or paper webs for food delivery, medical, and heavy-duty retail packaging. The nominal thickness of the extruded polymer melt layer is calculated using the continuous mass conservation equation:
Where h represents the final coating thickness, Q is the volumetric flow rate of the extrusion screw, ρm is the molten polymer density, W is the active T-die deckle width, v is the line take-up speed of the substrate, and ρs is the solid polymer density. OYANG’s High-Speed Extrusion Coating Lamination lines utilize automatic internal-deckle T-dies and scanning radiometric thickness gauges to dynamically trim Q relative to v, holding barrier uniformity to within ± 1% across line speeds of 250 m/min.
130,000㎡ Smart Factory: Where Precision Meets Scale
OYANG Group’s production headquarters in Wenzhou, China operates as an integrated Industry 4.0 production ecosystem. The entire facility is orchestrated by an advanced Manufacturing Operations Management (MOM) platform, synchronizing CAD/CAM engineering designs directly with automated machining cells.

To ensure equipment structural longevity exceeding 15 operating years, all core structural assemblies—including heavy-duty wallboards, eccentric drive shafts, and slitting knife housings—are machined strictly in-house. Our precision manufacturing center features Japanese MAZAK and OKUMA 5-axis CNC machining centers operating in climate-controlled workshops, achieving parallelism and flatness tolerances of ≤ 0.015 mm to eradicate mechanical harmonics at high speeds.
