Lately, Toray Industries, Inc. declared that it is going to buy large-scale 3D suction blow-molding machines from Germany-based Kautex Maschinenbau. Kautex Maschinenbau is the largest extrusion blow-molding machinery manufacturer in the world.Toray Industries’ aim is to enhance its mold processing technologies and substances with the new machinery. The company, thus, seeks to manufacture turbo ducts, which are used in turbocharged automobiles.
It is the first time that a Japanese engineering plastics manufacturer is installing such machinery. Toray plans to install the machinery at its plant in Nagoya by August this year while bringing it into operations from the coming October.
Toray’s latest decision will help it fortify its bond with Kautex Maschinenbau. Also, the company will be able to use its expertise in developing such solutions and materials, which employ mold processing technologies. In recent past, the market has seen a large number of compact turbocharged cars with small engines having turbochargers, since automakers seek to enhance vehicle fuel efficiency. However, metal was used earlier to make turbocharged engines. But, resin materials are in use for the same now which help cut the weight of the vehicle and pave a room for improved designs. In particular, automakers are using high-performance engineering plastics such as polybutylene terephthalate (PBT) resin, polyphenylenesulfide (PPS) resin, and polyamide (PA) resin. The reason being they ensure features like high heat resistance and chemical resistance.
Usually,suction blow-molding and injection molding methods are used to mold resin-based turbo ducts. But, suction blow-molding is more in use due to its flexibility when designing turbo ducts. It lets automakers build long and complex shaped ducts while ensuring a reduced cycle time for molding every unit.
Toray has a wide range of engineering plastics which can be used for making turbo ducts. These plastics comprise AMILAN® PA resin, TORELINA® high-performance PPS resin, andTORAYCON® PBT resin. Kautex’s suction blow-molding machinery will help Toray in gathering technical knowledge about new molding methods.
The turbocharged vehicle market is expected to report consistent growth on international grounds. Also, the count of automobiles is expected to increase by almost two folds as compared to the present count, thereby touching 39 million by 2020. Consequently, Toray has plans to further stretch its engineering plastics sales for turbo ducts. For the same, it will promote close collaboration with its Automotive Center, which manufactures modern materials and composites for automobiles, and will best use its new suction blow-molding machinery to actively carry out joint-development initiatives with patrons.
