The units have five working stations: three for the mechanical cap forming and the other two for compound application and centrifugation.
1º Station: Calibration and Pre-curling.
This station by means of a die corrects the earings from the shell cupping process and starts to curl the cup.
2º Station: Pre-curling.
Further curling, started in the previous station, continues by means of a die.
3º Station: Curling and Lug forming.
Through an axial pressure, the curling and lugs are formed.
4º Station: Lining.
By programming the weight of the compound, number of turns and the rotation speed the compound is applied.
5º Station: Centrifugation.
It rotates in opposite direction with respect to the previous station to break the tendency of compound to flow in the same direction and give a better distribution of material with less compound. |
