Injection Molding Mixing Nozzle And Filter

The SMN Injection Molding Static Mixing Nozzle creates homogeneous mixing of polymer melt during injection. The resulting high viscous polymer melt flow is homogeneous with regard to colorant, additives and temperature.

Filter for Injection Molding Static Mixing Nozzle (Type SMF)
The optional SMF Filter is installed inside of the Static Mixing Nozzle to protect the hot runner system and mold when processing regrind materials by avoiding clogging and/or damage with debris carried along with the feed pellets.

InjectionGrid Protection Disk for Mixing Elements (Type GPD)
The optional GPD Grid Protection Disk is installed inside of the Static Mixing Nozzle upstream the first mixing element. During the start-up operation it avoids a possible so called “cold-start” damage of the mixing element grid by plugs of not completely molten and thus partly solid polymer plugs originating from the transition part between the end of the barrel and the Static Mixing Nozzle

Benefits & Function
The SMF Filter is designed to be used with the SMN Injection Molding Mixing Nozzle. The purpose and functionality of the SMF filter are numerous:
