This is a threading system by lowering an arm onto the cover, in which there is an individual mold with the shape appropriate to that cover, rotated by a high quality servo motor with torque, speed and pressure control on the cover.


This arm is fixed in a pneumatic "up and down" system, with height adjustment. The vials, already with the cap properly positioned in their mouth, are stopped under the threading machine, the system descends so that the mold engages the cap and starts threading until the pre-set torque level is reached.

The system has an independent electro-electronic control panel  which can be coupled in pre-existing lines or already come incorporated in the Contain packaging line. It is ideal for flasks where the cap is in an internal position or that prevents its threading by the continuous linear system or even those that require pressure to start its threading.
