Modelo: Airbag System
Marca: htd
Lugar de origen: PORCELANA
Posicionamiento del producto:
El anillo de retención del inflador HTD es el componente crítico de soporte de carga dentro del sistema de bolsa de aire del automóvil, diseñado para anclar de forma segura y precisa el inflador a la estructura de la carrocería del vehículo. Actuando como el "esqueleto estructural" del módulo de bolsa de aire, debe resistir y transferir instantáneamente la tremenda fuerza de reacción del encendido del inflador y las cargas de impacto al marco del vehículo durante una colisión, al mismo tiempo que garantiza la estabilidad posicional absoluta del inflador. Fabricado con aleaciones de acero/aluminio de alta resistencia mediante procesos de estampado/fundición a presión de precisión, logra la integración perfecta de resistencia ultraalta, excelente resistencia a la fatiga, posicionamiento preciso y antiaflojamiento confiable bajo cargas dinámicas extremas, sirviendo como base mecánica para el despliegue oportuno y preciso del sistema de bolsa de aire.
