Apparatus and methods for converting resin into colored finished or semi-finished plastic parts include a process machine having a barrel, a rotatable screw inside the barrel, and a color feed conduit assembly extending into the barrel for passage of liquid color through the color feed conduit assembly into proximity with the screw.

Apparatus and methods for converting granular plastic resin into colored finished or semi-finished plastic parts include a process machine having a barrel with a vertically opening feed throat, a rotatable screw inside the barrel, and a color feed conduit assembly positioned at least partially within the process machine and extending into the barrel for passage of liquid color downwardly through the color feed conduit assembly into proximity with the screw.

Systems and processes for forming seals. The seals have graphene embedded in the seal. The graphene-embedded seals exhibit improved wear resistance over seals without graphene.
