Melt filter SMF series

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. Benefits & Function The SMF Filter is designed to be used with the SMN Injection Molding Mixing Nozzle. The purpose and function of the SMF filter are numerous: Protects hot runner system and mold by avoiding clogging and/or damage caused my metal pieces accidentally introduced with the feed pellets to the injection molding machine (staples, metal chips, paper clips, etc). Retains semi-molten polymer pellets until melted for incorporation into the polymer melt. For customers with poor thermal control systems, the SMF Filter acts as an upstream “breaker-plate” to prevent “cold-start” crushing of the mixing elements. Designed to retrofit into the SMN Injection Molding Mixing Nozzle without nozzle modification SMF Filter O.D. = SMN Mixing Element O.D. Length of one (1) SMF Filter = Length of two (2) SMN Mixing Elements.
