Available in both halogen and non-halogen products, including grades with UL Yellow Card rating, Maxxam FR products can be customized for specific performance needs. Tool Steel • P20 tool steel is acceptable when proper processing and shut down procedures are followed • Chrome plating or PH stainless steel is preferred for all halogen-based systems • The use of stainless steel in hot runner systems is highly suggested • Avoid the use of aluminum when designing production tools Vents • Place vents at the end of fill and anywhere potential knit/weld lines will occur • All vents need to be vented to atmosphere • Cut vent depths to 0.0010"–0.0015" with a minimum 0.040" land length. Increase the vent depth to 0.010" at 0.100" away from the cavity and vent to atmosphere. • Vents should be placed at the intersection of each 90° bend in the runner system off of the cold slug well and vented to atmosphere PROBLEM CAUSE SOLUTION Black Specks Contamination • Purge barrel with general purpose PP • Verify correct nozzle is being used • Pull screw for cleaning Degraded/overheated material • Decrease melt temperature • Decrease back pressure • Decrease injection speed • Use appropriately sized barrel Brittleness Degraded/overheated material • Decrease melt temperature • Decrease back pressure • Decrease injection speed • Use appropriately sized barrel Gate location and/or size • Relocate gate to nonstress area • Increase gate size to allow higher flow rate and lower molded-in stress Burning Process related • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease injection rate Mold design • Clean, widen and increase number of vents • Increase gate size to reduce shear Fibers/Minerals on Surface or Uneven Surface Appearance Melt temperature too low • Increase melt temperature • Increase mold temperature • Increase injection speed Insufficient packing • Increase hold pressure and time • Increase shot size Flash Injection pressure too high • Decrease injection pressure • Increase clamp pressure • Decrease injection rate • Increase transfer position Excess material volume • Adjust transfer position • Decrease pack pressure • Decrease shot size • Decrease injection rate Melt and/or mold too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease screw speed Loose clamp • Reset mold height • Increase clamp tonnage Troubleshooting Recommendations PROBLEM CAUSE SOLUTION Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection rate Mold design • Enlarge or widen vents and increase number of vents • Check that vents are unplugged • Check that gates are unplugged • Enlarge gates and/or runners • Perform short shots to determine fill pattern and verify proper vent location • Increase wall thickness to move gas trap to parting line Shot size • Adjust transfer position to 98% full • Increase shot size Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression Shrink Too much shrink • Increase cooling time • Decrease mold temperature Too little shrink • Decrease cooling time • Increase mold temperature Sink Marks Part geometry too thick • Reduce wall thickness • Reduce rib thickness Melt too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature Insufficient material volume • Adjust transfer position • Increase shot size • Increase injection rate • Increase packing pressure Troubleshooting Recommendations (continued) PROBLEM CAUSE SOLUTION Sticking in Mold Overfilled cavity • Decrease injection rate and pressure • Decrease hold pressure • Adjust transfer position • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease cooling time Mold design • Increase draft angle • Polish cores in direction of ejection Part is too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time Warp Process related • Increase cooling time • Increase melt temperature • Increase pack pressure • Increase pack time • Decrease mold temperature Mold design • Inspect for non-uniform mold cooling Part design • Inspect for non-uniform wall thickness Temperature control unit incorrect temperature • Check settings • Inspect thermocouple Weld Lines Melt front temperatures are too low • Increase pack and hold pressure • Increase melt temperature • Increase injection rate • Increase mold temperature Mold design • Increase gate size • Perform short shots to determine fill pattern and verify proper vent location • Add vents and/or false ejector pin • Move gate location 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.
