A standard automotive nerve wheel rim is manufactured from a rectangular sheet metal
- The metal plate is bent to production a cylindrical sleeve with the two free edges of the sleeve welded together
- At least separate cylindrical flow spinning employment is carried out to obtain a given thickness shadow of the sleeve â in particular comprising in the zone intended to constitute the outer chair an angle of inclination relative to the axial direction
- The sleeve is then shaped to obtain the rims on each side with a radially inner cylindrical wall in the zone of the outer seat and with a radially outer frusto-conical wall inclined at an angle corresponding to the standard inclination of the rim seats
- The rim is then calibrated.
