A gradient blue bar graph showing the typical tooling lead time of different materials with aluminum extrusions (2) in comparison to vinyl extrusion (4), stampings (7), powder metal (10), roll form (12), castings (17), and injection molding (17). The left axis of the graph shows the number of weeks in increments of 2 weeks starting from 0 at the bottom all the way to 20 at the top. Source: Aluminum Extruders Council (AEC)
