Additional draft may be required for grained/textured surfaces. 4 Nymax Polymer Formulations Troubleshooting Recommendations Problem Cause Solution Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection rate • 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 shot size • Adjust transfer position to 98% full • Increase cushion Brittleness Wet material • Check moisture. Degraded/ overheated material • Decrease melt temperature • Decrease back pressure • Use smaller barrel • Decrease injection speed Gate location and/or size • Relocate gate to nonstress area • Increase gate size to allow higher flow rate and lower molded in stress 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 Processing Guide 5 Problem Cause Solution 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 • Increase shot size • Increase injection rate • Increase packing pressure • Increase gate 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 Shrink Too much shrink • Increase cooling time • Decrease mold temperature Too little shrink • Decrease cooling time • Increase mold temperature Troubleshooting Recommendations 6 Nymax Polymer Formulations Troubleshooting Recommendations Problem Cause Solution 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 Wet material • Check moisture.

This paper concentrates on a new class of TPEs that can bond to a number of substrates with dissimilar surface energy or polarity, such as PP, ABS, PC and COPE, etc., called “universal overmolding TPE.” Also, this new technology can reduce cost by reducing the number of TPEs needed for different applications.
