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.
Cold Slug Wells
• Place these wells at the base of the sprue to capture the cold material first
emerging from the nozzle

Vents should be placed at the intersection of each 90° bend in the runner
system off of the cold slug well and vented to atmosphere
Black Specks
Contamination
• Purge barrel with general purpose PP
• Verify correct nozzle is being used
• Pull screw for cleaning
Degraded/overheated
material
• Decrease melt temperature
• Decrease injection speed
• Use appropriately sized barrel
Brittleness
Degraded/overheated material
• Decrease melt temperature
• Decrease injection speed
• Use appropriately sized barrel
Gate location and/or size
• Relocate gate to nonstress area
• Increase gate size to allow higher flow rate and
lower molded-in stress
Burning
Process related
Mold design • Clean, widen and increase number of vents
• Increase gate size to reduce shear
Fibers/Minerals on
Surface or Uneven
Surface Appearance
