Incomplete Fill Melt and/or mold temperature too cold • Increase nozzle and barrel temperatures • Check thermocouples and heater bands Shot size • Increase shot size • Adjust transfer position to 98% full • Increase cushion • 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 Brittleness Degraded/overheated material • Decrease melt temperature • Decrease back pressure • Use smaller barrel Gate location and/or size • Relocate gate to non-stress area • Increase gate size to allow higher flow rate and lower molded-in stress Wet material • Check moisture. Sink Marks Melt too hot Insufficient material volume • Increase shot size • Increase packing pressure Part geometry too thick • Reduce wall thickness • Reduce rib thickness Flash Injection pressure too high • Decrease injection pressure • Increase clamp pressure • Increase transfer position Excess material volume • Decrease pack pressure • Decrease shot size Melt and/or mold temperature too hot Loose clamp • Reset mold height • Increase clamp tonnage Shrink Too much shrink • Increase cooling time Too little shrink • Decrease cooling time Burning • Reduce decompression • Clean, widen and increase number of vents • Increase gate size to reduce shear Wet material • Verify material is dried at proper condition Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression • Verify material has been dried at proper conditions Incorrect nozzle • Use reverse taper tip Weld Lines Melt front temperatures are too low • Increase pack and hold pressure • Increase gate size • Identify end of fill pattern and verify proper vent location • Add vents or increase vent width • Move gate location Warp • Reduce injection speed • Increase pack pressure • Increase pack time • Increase cool time Mold design • Non-uniform mold cooling Part design • Non-uniform wall thickness Thermolator incorrect temperature • Check settings • Inspect thermocouple Sticking in Mold Overfilled cavity • Decrease injection rate and pressure • Decrease hold pressure • Decrease cooling time Part too hot • Decrease barrel temperature • Increase cooling time • Increase draft angle • Polish cores in direction of ejection Black Specks Contamination • Purge machine Degradation • Reduce melt temperature • Reduce screw speed • Reduce back pressure Machine related • Check for wear on screw, barrel or check ring Delamination • Purge barrel to eliminate material contamination • Reduce sharp corners in material flow path • Increase venting Discoloration Oversheared material • Decrease melt temperature • Reduce residence time Mold design • Increase gate sizing Dry material • Check moisture of material to ensure it is within the recommended moisture percentage for molding 1.844.4AVIENT www.avient.com Copyright © 2021, Avient Corporation.

Microbe growth on plastic can deteriorate performance and also lead to undesirable staining and odor issues. To better evaluate how to protect plastic parts from microbial attack, Avient conducted a study to screen a variety of plastic substrates for susceptibility using American Society for Testing and Materials (ASTM) G21 (fungi susceptibility), Japanese Industrial Standard (JIS) Z2801, and modified ASTM E1428-15a (bacterial susceptibility) test standards.
