Electrical thread unscrewing units

The electrical unscrewing unit is a separate drive mechanism for the thread demoulding at injection moulding tools.

After the initial operation of the tool or after a voltage drop the reference face (close touch /top of the tool) has
to be started manually by means of the button “reference run”.

If the button “reference run” is pressed, the unit drives with a slow velocity (about 100 U/min and 3 Nm turning moment) on the top of the tool, to determine the reference point.

Subsequently the operator can make
a “test-run” by means of the buttons on the controller (extend and retract cores).
If this operation is finished, it can be changed to continuous operation.
