So, you need a metal cylinder. Maybe it’s an enclosure, maybe it’s for piping or tubing, maybe it’ll even end up in someone’s kitchen as a fire extinguisher. First things first, though, you need to figure out how you’re going to get your hands on that cylinder. But wait: actually, you need more than one. You need thousands. So you’re probably going to want to have them made for you, rather than bought off the shelf. Now we’re getting somewhere, and this is where this blog may come in handy. Basically, there are two methods of producing cylinders like these: metal spinning, or deep-drawn stamping. As expert metal spinners, we’re here to tell you why this process is superior.
Economics: The main benefits of metal spinning are lower costs nearly across the board, in aspects from tooling costs, preproduction, and initial investment, to overall energy efficiency and in-process secondary operations.
Part strength: The specifics of the metal spinning process, as compared to stamping a part, lead to greater ductile strength in a finished piece, and a lower chance of crack propagation if a defect does occur.
Shape versatility: For non-uniform hollow shapes, like concave or convex parts, elliptical shapes, or cones, metal spinning is the clear answer over deep-drawn stamping.
