VERTICAL NECKING MACHINE 2105

The Vertical Necking Machine is designed to neck down balloon tubes.
This process step comes prior to the balloon forming process. The target is to reduce the tube diameter beforehand in order to eliminate the calibration process after balloon forming. The tube is heated partially by a specifically designed air nozzle and the diameter is reduced by axial moving of two linear slides with different speed and travel.

The final diameter of the tube can be changed by adjusting either temperature, speed, travel or relative motion of the two axis.
The parameters of every product can be stored as recipe in order to achieve reproducibility.
