Our new system technology:
From blank to tube shell to housing in an instant
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.
The characteristics of the compact fast system result in compelling business benefits:
• Coil in – cell housing out
• Down to 0.15 mm material thickness
• Cell housing with final length – no additional cutting
• Weld seam position anywhere in final housing
• Short change-over times for different cell geometries
• Very compact system footprint
• Overall cycle time < 2 sec
• Ramp-up possible
Short Profile:
Processes: cutting, forming, laser welding, expanding
Cycle Time: < 2 sec (1 sec target)
Uutput: 1620 parts/hour (90 % tech. availability)
Cell housing: L: 50 - 500 mm
W: 25 - 70 mm, H: 100 - 150 mm
Material: 0.15 – 0.6 mm stainless steel or other on request
Footprint: 8 x 9 m expected
