What aluminum extrusion methods allow curved designs for pet waste bins?

Several aluminum extrusion methods can create curved designs for pet waste bins, offering both functionality and aesthetic appeal. The most common technique is stretch bending, where extruded aluminum profiles are stretched over a curved die. This method maintains the profile's cross-section while achieving smooth arcs. Rotary draw bending is another precise method, using dies and mandrels to create tight radii without wrinkling. For complex curves, custom extrusion with flexible tooling allows unique shapes directly from the extrusion press. Additionally, roll bending passes straight extrusions through three rollers to create large-radius curves. These methods enable durable, weather-resistant pet waste bins with ergonomic curved handles, rounded corners, and decorative elements that blend into outdoor environments while providing necessary durability for public spaces.
