Injection nozzle M

for meltlow-pressurewith static mixer

Static mixers are being increasingly employed for processing thermoplastics. Perfect melt homogeneity (temperature, coloring) is one of the most important conditions for the production of faultless injection molded articles. The mixer homogenizes the melt by exponential layer formation, by rotation and eddy formation and by velocity differences between the partial flows. For the injection molding process a machine nozzle was developed, which is characterized by high mixing capacity with low pressure loss. The durable mixing elements are corrosion resistant and can be used also for abrasive media (until approx. 30% glass fiber portion). Mixing nozzle design The mixing nozzle was designed and calculated by FEM programming which captivates the following advantages: The construction is implemented using the building block system. The mixing nozzle can be installed while in a cold state and does not require readjustment or tightening after warming up. At the correct operating temperature the nozzle tensions overlay and stress optimally due to calculated thermal expansion. Criteria for this nozzle type • Reduced dyestuff costs • Homogeneous melt flow • Avoidance of flecks and cloudiness • Reduction in the reject rate • Improved dimensional accuracy • Shortened cycle times • Extension of the range of employment, also applies to older injection molding machines • Better product quality with reclaimed materials The mixing nozzle provides the homogeneity of the polymer and leads to increased color saturation in the molded parts.
