Injection Molding - Thermoplastics Injection molding creates molded parts by injecting heated, molten plastic materials into a mold, which are then cooled and solidified. This design flexibility also enables engineers to reassess assemblies and take advantage of consolidating multiple parts into one molded offering. Injection molded long fiber composites deliver comparable performance characteristics to metals and offer excellent strength-to-weight ratios.

Mold Design Recommendations Gates 1. Hot runner molds are acceptable and should be sized by the manufacturer. Maintain a minimum draft angle of 1° per side. 4 Therma-Tech Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures • Increase pack and hold pressure • Increase nozzle tip diameter • Check thermocouples and heater bands 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 • Increase cushion • Decrease transfer position Brittleness Low melt temperature • Measure melt temperature with pyrometer Degraded/ overheated material • Decrease melt temperature • Decrease back pressure • Use smaller barrel/excessive residence time • Decrease screw rpm Gate location and/or size • Relocate gate to nonstress area • Increase gate size to allow higher flow rate and lower molded in stress Fibers on Surface (Splay) Melt temperature too low • Increase injection speed • Increase screw rpm Insufficient packing • Increase pack and hold pressure, and time Processing Guide 5 Sink Marks Part geometry too thick • Reduce wall thickness • Reduce rib thickness • Maintain nominal wall thickness Melt too hot • Decrease nozzle and barrel temperatures Insufficient material volume • Increase pack pressure/time 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 too hot • Decrease screw speed Excessive Shrink Too much orientation • Increase packing time and pressure • Increase hold pressure • Decrease melt temperature • Decrease injection speed • Decrease screw rpm • Increase venting Not Enough Shrink Too little orientation • Decrease packing pressure and time • Decrease hold pressure • Increase injection speed • Increase screw rpm • Decrease cooling time 6 Therma-Tech Burning Melt and/or mold too cold Mold design • Clean, widen and increase number of vents • Increase gate size or number of gates Moisture • 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 are too low • Increase pack and hold pressure • Increase vent width and locations Mold design • 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 • Decrease injection pressure and injection rate Mold design • Increase number of gates Sticking in Mold Cavities are overpacked • Decrease injection rate and pressure • Decrease pack and hold pressure Mold design • Increase draft angle Part is too hot 1.844.4AVIENT www.avient.com Copyright © 2020, Avient Corporation.
