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 channel inlet and outlet are offset by 90°.
The conductive surfaces have a curved geometric definition. Homogenous mixing is achieved by two effects; exponential layer formation and speed differences of part flows. This enables continual mixing on a minimal mixing line.
HOMOGENISATION OF TEMPERATURE
Polymers are poor conductors of heat. Tests in extruder systems have shown that significant temperature differences can occur at the screw conveyor outlet (up to +/- 20°C).
This problem leads to tolerance deviations in the injection moulding process and therefore to an increased reject rate; especially among technical parts.
Temperature differences also mean increased cycle times because the max. temperature peaks in the moulded parts must be considered during cooling. A reduction of the cycle time means additional savings in operating costs.
