Abstract
A method and apparatus for extrusion coating both sides of a metal strip. A metal strip, such as aluminum alloy strip, is moved through a pre-conditioner, two extrusion dies, a post-heater and a cooling system. Both sides of the strip are coated with thin coatings of thermoplastic polymers. The coated metal strip is useful for containers, such as cans and can ends, as well as for automobiles, appliances, aerospace, construction and electrical devices.
