1. Analysis of limitations of traditional cutting process
Hydraulic die-cutting technology
Stamping and forming with steel molds, suitable for mass production
Typical parameters: pressure 20-30 tons, speed 3-5 pieces/minute
There are defects such as low material utilization (average 65%-70%) and long mold change time (2-3 hours)
Current situation of manual cutting
Labor-intensive operation, skilled workers cut about 200 pieces a day
Accuracy is significantly affected by human factors, and the dimensional deviation can reach ±2mm

2. Breakthrough in automated cutting technology
CO₂ laser cutting system
Technical features: 10.6μm wavelength laser beam, power 300-500W
Advantages:
Cutting accuracy ±0.1mm (20 times higher than die-cutting)
Contactless processing to avoid material deformation
Complex pattern one Secondary molding (supports DXF/AI format)
Visually guided CNC cutting bed
Integrated 3D scanning positioning system (accuracy 0.02mm)
Intelligent nesting algorithm improves material utilization to 85%-90%
Application case of a certain enterprise:
Daily production of aprons increased from 800 to 2,500
Scrap reduced by 42% (saving 18 tons of TPU raw materials per year)

III. Special material processing technology
Multi-layer composite material cutting solution
For TPU+non-woven composite aprons
Adopt layered cutting technology (laser parameters are adjusted in stages)
Ensure that each layer of material is cut synchronously and without melt adhesion
Anti-deformation treatment of elastic fabrics
Pre-stretching fixture (tension control ±5N)
Low-temperature cutting technology (workbench temperature 15-18℃)
The rebound rate of the finished product is controlled within 3%

IV. Quality inspection standard system
ISO 13935-2 seam strength test
Peel strength ≥ 35N/cm (food-grade apron standard)
Visual inspection system
Defect recognition based on deep learning (CNN model)
Misdetection rate <0.5%, inspection speed 120 pieces/minute

V. Future development trends
Application of digital twin technology in cutting process
AR-based remote process guidance system
Zero-emission laser cutting technology research and development
