Toyoda Gosei Co., Ltd. has introduced a new turbo duct made entirely made up of plastic. This has tremendously reduced the weight by half and will contribute significantly to the environmental performance of automobiles. The new lightweight plastic turbo duct is used on the new HiAce for international markets that Toyota Motor Corporation launched in February 2019.
Turbo ducts offer uses in sending compressed air to cylinders to raise engine output. They have conventionally been made of various metal, rubber and plastic sections to ensure high pressure and heat resistance along with the ability to absorb engine vibration.
For this newly developed all-plastic turbo duct, Toyoda Gosei underwent adoption of a suction blow molding technique capable enough of forming the long, complex duct shape to mold the entire duct of plastic. This achieved a weight reduction of approximately fifty percent. Usage of the soft plastic for the material and design alterations such as a bellows shape in some sections ensure the duct’s pressure and heat resistance and vibration absorption performance.
With its remarkable expertise as a specialist in the field of rubber and plastics, Toyoda Gosei will continue to actively pursue lighter weight products and other new technologies and thereby, setting high standards and benchmarks in the industry.
