The GSM mixing nozzle is used for processing thermoplasts in injection moulding processes.
The design principle of the GSM mixer is unique. Each element divides the diameter into two channels, which come together at half of the diameter and then expand again.
The needle type shut-off nozzle (NVD) is used to process thermoplastics and liquid media. The choice of nozzle size depends on the flow of injection volume (cm3/s).
The NVD (shut-off nozzle) is responsible for the clean separation of the molten mass and reliable shut-off during dosing and is the prerequisite for fault free, economic production.
The NVD is opened and closed using a pneumatic or hydraulic control. This nozzle type can also be controlled via a rod. Shorter cycle times are enabled and uncontrolled loss of mass is prevented with the controlled separation of the mass flow.
