Longer prismatic cell housings are usually produced either with continuous roll-forming or cycled pressforming processes. Weil Technology now offers a new alternative and fast process with a compact system allowing for stainless steel housings with wall thickness of as low as 0.15 mm.

The innovative system can produce a cell housing made of stainless steel directly from a coil or blank. We draw on our decades of expertise in short tube production. After the optional blank trimming, a tube is rounded in the first part of the system and reliably laser-welded. In the next step, the tube is expanded into its final shape and calibrated. This allows stainless steel cell housings with material thicknesses as low as 0.15 mm to be produced economically and at high outputs in a compact space.
