Type S


The needle which moves axially in the nozzle is held in the closed position by the force of the spring. The melt pressure, coming out of the extrusion unit pushes back the needle and opens the hole for injection at 180 bar. After the injection process and pressure decrease, the nozzle is closed again, according to the movement of the spring.
