PA6 Automotive Intake Manifold
문제 현상
The intake manifold cracks at the vibration weld, and strength decreases after long-term thermal aging
원인 분석
The engine compartment temperature is high with frequent thermal cycling, and PA6 needs glass-fiber reinforcement and long-term thermal aging resistance; the weld line quality and welding parameters of vibration welding directly affect sealing and strength
해결 방법
①Select 30-35% glass-fiber reinforced thermal aging resistant grades; ②optimize vibration welding parameters for weld strength; ③verify life with thermal cycling and thermal aging tests; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
The intake manifold is a classic high-temperature application of glass-fiber PA6; the grade's aging resistance rating and welding process verification are the double insurance of batch reliability; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
