The nozzle head is designed in the way that the 2K-Sandwich valve is integrated into this particular head.

The nozzle head is adapted to the main plasticizing unit. The second component will be guided to the nozzle head.

This can be done with a compactly integrated design or a special placed sprue bushing on the nozzle head.

The nozzle head type is recommended rather for large machines with no much mold changes. The following alignments are preferred: parallel or "Backpack". A great advantage of this version is that the intermediate plate is not needed.

This results in no limitation in the mold installation space (space between the plates). The accessibility of the nozzle is very good. The nozzle head takes care for the contact force.  Consideration must be given to the contact force of the second unit.
