The glass tube to be profiled must first be joined on a tube whose internal diameter is slightly greater than the maximum diameter of the tool to be extruded.

For assembly, thread the steel cable on which the tool is fixed into the glass tube, sleeved side. Pass the assembly through the torch and the upper gripping system, then insert the sleeve into the seal of the lower mist. Then wind the cable on the upper and lower pulleys to reach the fixing bracket of the right carriage, at the rear of the machine. Pull the cable tight. Finally, squeeze the glass tube into the upper gripping system.

The connection of the lower stop must be connected to the nitrogen distribution circuit. The nitrogen flow rate is adjusted via an adjustment valve.

As with the calibration, the heating is done from the bottom up. The torch and tool travel speed should be adjusted to maintain a constant T ° of the glass during the extrusion process.

The cycle is controlled either by the operator (manual version) or by the machine (semi-automatic version)

Once in the low position (adjustable), an electric sensor stops the process [only for the semi-automatic version].
