These materials combine the performance of select engineering resins with reinforcing additives, such as carbon powder, carbon fiber, nickel-coated carbon fiber and stainless steel fiber, for low-to-high levels of conductivity depending upon application requirements. PROBLEM CAUSE SOLUTION Incomplete Fill Melt and/or mold temperature too cold Mold design Shot Size • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection speed • Increase pack and hold pressure • Increase nozzle tip diameter • Check thermocouples and heater bands • 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 • Increase shot size • Increase cushion Brittleness Melt temperature too low Degraded/Overheated material Gate location and/or size • Increase melt temperature • Increase injection speed • Measure melt temperature with pyrometer • Decrease melt temperature • Decrease back pressure • Use smaller barrel/excessive residence time • Relocate gate to nonstress area • Increase gate size to allow higher flow speed and lower molded-in stress Fibers on Surface (Splay) Melt temperature too low Insufficient packing • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase pack and hold pressure, and time • Increase shot size • Increase gate size Sink Marks Part geometry too thick Melt temperature too hot Insufficient material volume • Reduce wall thickness • Reduce rib thickness • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase shot size • Increase injection rate • Increase packing pressure • Increase gate size Flash Injection pressure too high Excess material volume Melt and/or mold temperature too hot • Decrease injection pressure • Increase clamp pressure • Decrease injection speed • Increase transfer position • Decrease pack pressure • Decrease shot size • Decrease injection speed • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease screw speed TROUBLESHOOTING RECOMMENDATIONS PROBLEM CAUSE SOLUTION Excessive Shrink Too much orientation • Increase packing time and pressure • Increase hold pressure • Decrease melt temperature • Decrease mold temperature • Decrease injection speed • Decrease screw rpm • Increase venting • Increase cooling time Not Enough Shrink Too little orientation • Decrease packing pressure and time • Decrease hold pressure • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase screw rpm • Decrease cooling time Burning Melt and/or mold temperature too hot Mold design Moisture • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease injection speed • Clean, widen and increase number of vents • Increase gate size or number of gates • Verify material is dried at proper conditions Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression • Verify material has been dried at proper conditions Weld Lines Melt front temperatures too low Mold design • Increase pack and hold pressure • Increase melt temperature • Increase vent width and locations • Increase injection speed • Increase mold temperature • Decrease injection speed • 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 Warp Excessive orientation Mold design • Increase cooling time • Increase melt temperature • Decrease injection pressure and injection speed • Increase number of gates Sticking in Mold Cavities are overpacked Mold design Part is too hot • Decrease injection speed and pressure • Decrease pack and hold pressure • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time • Increase draft angle • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time TROUBLESHOOTING RECOMMENDATIONS www.avient.com Copyright © 2020, Avient Corporation.

This method is used for various polymers, including long fiber reinforced thermoplastics (LFRT or LFT). LFTs use reinforcement fibers (e.g., glass or carbon) that are in parallel alignment and of uniform length (typically 12 mm), offering metal replacement performance. Injection molded long fiber composites deliver comparable performance characteristics to metals and offer excellent strength-to-weight ratios.
