Systems and methods are disclosed for adjusting thickness of an extrudate in an extrusion die system. A lip adjustment assembly includes an engagement member connected to a movable lip of an extrusion die and being movable in a first and second direction opposite the first direction; an actuator configured to move the engagement member in the first and second directions; a coupler connected to both the engagement member and the actuator and disposed between the engagement member and the actuator; and an insulator on the coupler and configured to impede conduction of heat from the engagement member to the actuator. When the engagement member is moved in the first direction, the movable lip is moved toward a second lip of the extrusion die, and when the engagement member is moved in the second direction, the movable lip is moved away from the second lip.
