The portfolio is specifically formulated for applications requiring high stiffness, tensile properties, heat resistance, impact performance, and durability in harsh environments while offering the ease of processing in most standard thermoplastic processing equipment. 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.
