Automotive Seat Ventiation Bag Heat Sealing Process
The heat sealing process for automotive seat ventilation bags primarily involves three key steps:
Material Preparation and Positioning
First, the 3D TPU mesh fabric (a composite of TPU film and mesh cloth) is arranged in a specific sequence to ensure optimal breathability and structural strength.
High-Frequency Welding or HF Fusion Sealing
The materials are then heated to a molten state using high-frequency or HF cutting/sealing machines, achieving robust welding while trimming excess edges. The welding temperature is typically controlled within the range of 150–200°C.
Finished Product Inspection and Finishing
Finally, the finished products undergo quality inspections to verify sealing integrity. Excess material is cleared, completing the processing stage.
This process is widely used in automotive seat ventilation systems to enhance comfort and durability.
