Hows it Made? -Kleen Kanteen

Stainless Steel Water Bottles 27 oz, Reusable Bottles | Klean Kanteen



Hi I just picked one of these up and was curious how it was made. Im thinking it was some type of deep drawing and then swaged?

Thanks!

Probably impact extrusion.

PS. fix your link

Extrusion uses a lot of energy and wastes a lot of material. On their website, they actually say the bottles are welded by hand. This allows them to make the curvy shapes like in the baby bottles. They’ll have a sheet of steel and cut it and form it then weld it together. They say there’s no lining, so it’s probably a double wall construction, essentially a small bottle inside a big one. The air is sucked out between them and then they’re sealed together.
