How does Puxiong high-frequency welding ensure the airtightness of TPU airbag heat sealing

1. Precision High-Frequency Welding Technology
Puxiong's 27.12MHz electromagnetic field technology achieves 0.1mm repositioning accuracy through laser-guided positioning, ensuring continuous homogeneous stitch-like seams on TPU materials. The process limits HAZ (Heat-Affected Zone) width ≤0.3mm, preventing material degradation. Test results show zero leakage under extreme conditions, certified to EN 12663 standards.


2. Intelligent Process Control
The AI-driven system auto-calibrates welding current (10–100A), voltage (2–10kV), and pressure (0.1–5MPa) based on material batch variations, eliminating 85% of operational deviations. Real-time impedance monitoring enables ±1% energy stability.


3. Extreme Environment Validation

  • Positioning Precision: Maintains 0.01mm accuracy at -40°C to +120°C
  • Ultra-Thin Welding: 0.2mm films processed via 2000Hz pulsed energy modulation
  • Pressure Endurance: Welded seams withstand 8.5MPa in cryogenic burst tests

4. Full Traceability & Compliance

  • PLC System: Stores 50+ parameter profiles with ISO-compliant data logging
  • Quality Metrics: Defect rate reduced from 0.8% to 0.02% in German luxury automaker applications
  • Certifications: EN 17942 welding safety standard compliance + latest regulatory approvals
