April 29th, according to new information Alcoa issued from Cleveland in the United States, Alcoa Transportation Products won the 2009 Outstanding Supplier Award for the Automotive Industry for its advanced vacuum die-casting technology (AVDC). And capital equipment category awards. The award was co-founded by Auto News, Ernst & Young Hua Ming, and the American Automotive Research Center to recognize suppliers of automotive parts, equipment, and services that pursue excellence, innovation, technological advancements, and outstanding operating results.
The vacuum die-casting technology (AVDC) of Alcoa's transportation and transportation products develops lightweight door assembly technology into a "system solution" that integrates casting alloys, processes and equipment, enabling automakers to have a larger presence in passenger cars and commercial vehicles. To reduce the weight of cars by 30%-35%, integrate components (60-70% BOM / component reduction), and reduce the manufacturing cost of lightweight door systems.
AVDC patented technology possesses the space stability of high-strength, high-toughness cast alloys and the dimensional advantages of large-size mold parts, making the interior cover plate of automobile doors more lightweight material choice besides composite printing aluminum plates or steel plates. This innovative patent has been applied by many of the world's leading automotive manufacturers, and has also been fully demonstrated in the GT-R, a high-performance sports sedan that has recently been partnered with Nissan.
A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application,prism: In optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.
Dispersive prism can be used to break light up into it's constituent spectral colors(the color of the rainbow).Furthermore, prisms can be used to reflect light or to split light into components with different polarizations.
Optical Prism include Right angle prism.Equilateral dispersing prism.Dove Prism.Corner Cube Reflectors.Beamsplitter, Powell prism, dove prism, wedge prism, penta prism etc.
