Points to note in the high-frequency production of car seat air bags

The high-frequency welding production of car seat airbags requires attention to material selection/placement, equipment calibration/parameter setup, operational standards/safety precautions, mold maintenance/cleaning, and finished product inspection/quality control. Detailed analysis follows:

I. Material Selection and Placement
Car seat airbags typically use 3D TPU mesh fabric composed of a TPU film layer, mesh fabric layer, and another TPU film layer. This material combination ensures optimal strength, durability, and breathability.
Prior to production, materials must be arranged on worktables in designated sequences and orientations to guarantee machining accuracy and efficiency.

II. Equipment Calibration and Parameter Setup

1. High-Frequency (HF) Welding Machine:
   • Adjust tuner to regulate HF output intensity
   • Set appropriate welding duration based on material properties
   • Verify proper functioning of temperature controllers/heating tubes
2. Mold Calibration:
   • Ensure precise alignment and horizontal balance of upper/lower dies to prevent weak welds or product deformation.

III. Operational Standards and Safety Protocols

• Follow strict startup sequence: Activate three-phase power supply → Power on control cabinet → Allow vacuum tubes/heating molds to preheat.
• Safety measures:
  • Maintain effective grounding system
  • Avoid operation in high-temperature/dusty/weather-exposed environments
  • Conduct regular equipment inspections/maintenance.

IV. Mold Maintenance and Cleaning

• Periodically check mold balance/insulation integrity; replace damaged components promptly.
• Post-operation cleaning: Remove residual particles/dust using compressed air to preserve welding quality and product aesthetics.

V. Finished Product Inspection and Quality Assurance
Conduct rigorous checks on:

• Weld integrity
• Edge trimming precision
• Structural durability
  Non-compliant products must undergo immediate rework/scrap disposal to prevent market circulation and safeguard brand reputation.

This process framework combines key operational specifications from global automotive part manufacturers and industrial safety standards, emphasizing both product performance optimization and workplace hazard prevention.
