Automatic Wheel Rim Production Line
We use the most advanced techniques for a fully automatic wheel rim welding, forming and press assembly:
Automatic sheet feeding - marking, coiler and flattener - butt welder - trimmer-planisher - edge nip - flare - edge conditioner - 3 roll formers - expander - edge conditioner- welder position locator - air leakage testing - disc auto loading system - assembling press
- Rim bead seat diameter--10”~12”
- Width of the strip--70 ~ 180 mm
- Thickness --1.8 mm ~ 3.0 mm
- Productivity 100%--6s/part
- Rim bead seat diameter--13”~18”
- Width of the strip--160 ~ 280 mm

The marking, coiling and flattening machine forms coiled hoops from flat strips. A marking system has been integrated into the coiler at the machine’s feed section, and the coiled hoops are produced with a short, flat section on both sides of the gap, thus allowing for a weld to be produced using flat clamping and welding electrode.
