I've been in the aluminum extrusion business for 28 years. Best description is.....a giant Play-doh machine that use's aluminum to make anything you can think of. I work the dies to ensure dimensions and quality. Over the years I've made everything from shower doors, the corner trim for pool tables, Freightliner grilles, bed rails for trucks, hurricane shutters.
For that the last 6 1/2 years I've worked in the Aerospace industry as the Die Repair Supervisor on the world's 2nd largest extrusion press (16,200 ton). It was made in the 1930's by Germany. After the war it was seized and while in transport to the US it sank to the bottom of one of the rivers over there. It was recoverd and made operational in St. Louis by Spectrolite until the company went under. It sat in storage for years until my company bought it and started prodccing in 2005. We currently extrude the parts that the wings are made from for Boeing, Air Bus and other's. We are taking over Alcoa's place in the aerospace field.
