Air Ducts

Heating and air conditioning ducts and consoles now provide temperature regulation to rear as well as front passenger seats. The consoles themselves are typically manufactured from ABS resins, as well as polypropylene and SMA resins. Both blow-molded and injection molded polypropylene is used to manufacture the air ducts that feed the console outlets. The air ducts themselves are complex and odd-shaped, yet at the same time lightweight and durable. They would be difficult to reproduce using any other family of materials.
