The units consist of five working stations: three dedicated to mechanical cap forming and two for compound lining and centrifugation.

1. Calibration and Pre-curling
   Sets the position for the shell cupping process and initiates the curling of the cup.
2. Curling
3. Forming
4. Lining
5. Centrifugation
   This station rotates in the opposite direction to the previous one to counteract the compound’s tendency to flow uniformly. This results in a better distribution of the compound with reduced material usage.
