What are the common problems with heat sealing of car air bags?

I. Poor Heat Sealing or Air Leakage

Causes: Incorrect heat sealing temperature, pressure, or time; or substandard material quality.

Impact: Airbags are prone to leakage, affecting seat support and comfort.

Solution: Adjust heat sealing parameters correctly, select stable quality materials, and perform an inflation test after heat sealing.

II. Poor Rebound After Heat Sealing

Causes: Airbag leakage, air pipe blockage, or locked switch.

Impact: Weak seat rebound, affecting comfort.

Solution: Check airbags and air pipes, adjust the air control valve, or open the switch.

III. Poor Appearance After Heat Sealing

Causes: Excessive heat sealing temperature or pressure, or uneven mold surface.

Impact: Brittle seals, mottled appearance, affecting aesthetics.

Solution: Adjust heat sealing parameters correctly and improve mold surface condition.

IV. Static Electricity Problems After Heat Sealing

Causes: The material itself is prone to static electricity.

Impact: Attracts dust, affecting appearance and performance.

Solution: Add an antistatic agent to the inner layer material.
